Great video. My dad's 2000 Chrysler Grand Voyager had this problem. Though it had no flashing lights, the AC was blowing out hot. He thought he needed a new slider switch. I noticed the compressor wasn't turning on yet it had a full charge of freon. So I went to Google and found this video. Thanks to this video, his AC is blowing out ice cubes today when it's 80° and he couldn't be happier. He has the single switch instead of the dual climate control but everything in the video worked the same. Excellent how-to. Thank you!
cobhc2448 Thankyou for your reply. Im here to help, I had alot of fun with these vans over the years. Ihave a few caravan videos on here , check out my Chennl and subscribe for new videos that im making. good luck with your van
If the ac and recirculation buttons persist in blinking after calibration then check and recharge the refrigerant. Easy to do with ~$30 cans with integrated pressure gauge and hose sold at WMart or auto stores. Worked for me today after multiple prior unsuccessful attempts to calibrate. AC works well again as a bonus!
I will do as you said...when it gets warmer. I still got the blinking two and under the hood, the compressor won't cycle or remain on when AC is off/on. No auto-store cans are gonna do the job...already tried. I gotta get the vac pump & manifold, do it right. I'll also replace both Schrader valves while I'm at it with new ones. Thanks, Stephen! What's odd is when I first got my minivan running again, the AC system was empty but there were no blinking LEDs.
The blend door sequence @ 4:23 fixed the no heat on drivers side--passenger side only blows heat- problem on my 97 Town and Country. Now heat works on both sides as it should 👍 The battery was recently replaced so that may have offset something. Happy it was a calibration issue. Many thanks to you for creating this video. Well done!
Great video, I have had this problem as well and didn't know how to correct it, but I did notice that after driving for a while the lights would stop blinking. I have also had the issue with the air or heat strength. Thanks for posting this, it's been a great help.
Thank you so much for this quick and informative video. Fixed the blinking lights on 1998 Plymouth Grand Voyager. Note for others. The problem started after I tried to start the van when the battery was very low. The low battery voltage must have triggered an error in the computer or something. This fixed it quickly.
I did this procedure on my dads van after replacing the defective blend door actuator, but it wouldn't stop showing fault codes. So, then i decided to do a hard reset on the bcm/ ecm (disconnect the battery for ten seconds then reconnect) and then I ran the procedure again, this time it successfully calibrated. Thanks for posting this video, though. It was a great help!
Russ Newton Sometimes you can get away with pulling the ICM /IOD ( I cant remember which one its called and I may be mistaking this term for the 2001-2007 4th Gen vans. and you will Get the same result. What that does is it Resets the BCM. and Not the ECM. I dont like pulling he BAttery terminals unless I really have to, especially if the Inspection on the vehicle is very close to being up. Then you have to spend time drive cylcing the car to set all the Monitors. Thanks for the reply on my Video, I Try to help people the best way that I can. Explaining everything in my videos so someone whos ever done it before can. Thanks again, Be sure to subscribe to my Channel. I will be doing another Caravan video soon on one I am Junking
Your Welcome Casey. Please if you will, subscribe to my channel. I have other caravan Videos. and I have a 1999 Dodge caravan I will be working on soon
Thanks Bro, This works perfectly, You just saved me a trip to the shop, Last time this happened it cost me about 60 bucks at the dealership to get them turned off. Thanks again.
Can't thank you enough for doing this video. I had a evaporator & heater door actuator strip some gears because the system was out of sync.. I took the actuator apart and turned the stripped gears 180 because of the limited travel that they have and it worked. I then put the system thru the calibration and BINGO all is well. Thank you!
Well I did it, I've put gas into the radiator circuit and did the calibration, and the answer for my question is yes, the van must have refrigeration gas, and something that you don't told, the Windows must be closed... Thanks for the video it was very useful! :)
I 'liked' this several weeks ago, not thinking that I would need it. However, after adding freon on a '98 T&C (That someone else had borrowed for a year.), I could feel cool air, but very little air flow. there were NO blinking lights, but I decided to try this procedure anyway. As it cycled through the steps, I got some great air flow! Now it seems to cool well!
I have a 1998 Plymouth Grand Voyager and there's heat coming out the drivers side but not the passenger side. Will recalibrating the blend door help with this?
Adding freon solved this problem on my 97 Town and Country. I took it to an AC shop, they performed a procedure "recharging the AC system" what I was told. After that no more blinking lights, my AC was blowing out cold air through the vents. Hope this helps
Taking care of this tonight! Just had AC charged and the lights are blinking. Mech told me he didn't know how to get them off! SMH. I think I may just show him how its done.....the power of RUclips!
I had this problem for two years and never could get the blend door test to finish. I tested my AC high and low with manifold gauges, condenser fans working good and the compressor clutch fine as well. Yesterday I turned the the heat all the way up and ran it until the evaporator got pretty warm. Then shut the car off turned the temperature selector to cold and in 30 seconds got the 20 degree drop on the evap core the blend doors moved all the way to cold and now I'm running 38 degrees and thos dang lights are off. Hope this helps someone fix their problem.
You are awesome,I never knew about this before, I was about to take apart the dash to look for a stuck blend door, because I was not getting heat and then I saw this video and I recalibrated and I now have heat, amazing thanks, why did the heat go off is the mystery,, but it now works,, maybe it had something to do with the blower which only works on high,, thanks for saving me a lot of trouble 👏👏
Very helpful thank you! It is too cold to properly calibrate but i had no heat whatsoever and after doing the calibration procedure(though not calibrated correctly due to it being below freezing) I have heat again! Phew i thought i was going to have to tear my dash apart in the middle of winter to fix this problem. Thanks again!
This worked!! Even though my problem was a little different... Blew hot all the time on driver... Also had lights blinking.. But Thanks.... It fixed it perfectly!
Felicitaciones desde México, Tamaulipas, Reynosa, muchas gracias funciono perfectamente, no dejes de subir vídeos por favor, gracias eres un profesional. Gran Voyager 1999, motor 3.8 L. Después de una falla con la pila se descalibro el sistema, desesperado busque y encontré tu vídeo gracias. Solucionado el problema. Congratulations from Mexico , Tamaulipas , Reynosa, thank you very much worked perfectly , do not let upload videos please, thank you a professional. Grand Voyager 1999 , engine 3.8 L. After a fault with the system stack descalibro , desperate look and found your video thanks . Fixed issue .
Ok, so I tried this, about 7 times. What I'm getting is, when I push the A/C and the wiper wash buttons for the start of it, all the lights light up, but, the A/C and the recirc are the only two lights that keep blinking back and forth intermittently. None of the other lights light up after the initial start process. They go out and stay out throughout the entire cycle. After about two minutes or so of blinking, the A/C and recirc go back to blinking at the same time as each other. It won't go through the normal cycle like yours shows. The other calibration works. I would LOVE to find the problem and fix this.
I noticed the air wasn't as cold as it used to be, so I did the calibration and my lights started doing the same thing. I reset the memory by pulling the fuse, but the problem remains the same.
nice of you for the help. got a question can I do the second step when the fan speed doesn't work properly it blows when it wants too, or should I replace the control. 99 caravan 4 cylinder 2.4L. thanks
Rito Venegas Sorry for the delayed reply. you should replace the fan motor or the resistor thats making it work when it wants to. do you know for sure if its the control??
905speedgta thanks for getting back to me, I replaced the a/c control panel and the recirc lights start blinking and no ac blowing plus now my fuel gauge, temp gauge, and other gauges don't work unless I unplug the new (used) panel. Also tried your steps and lights on the recirc just blink and don't function like your calibration video. one more thing the old controls didn't blink at all does that mean they were bad? get back at me plz.
Great video, I have read the repair manuals quite often regards to heater and A/C work and many other repairs but never saw this outlined, maybe its in the owners manual but never in all my years of owning this generation Caravan's have I read, seen or heard anything about this procedure.
Wow...how did you figure this out? You're a genius. I have a 98 Grand Caravan - All the lights in that section are flashing - not just the recirculate and a/c. Will be trying this and reporting back.
Hi, I have a question... In the video you say that the outside temperature must be warm, but what about the blown air? My voyager hasn't refrigeration gas inside the radiator circuits, could this calibration works without the gas?
Thanks this is great. I've just gotten a 98 Chrysler (UK) Grand Voyager with this very issue, although I'll have to wait until later in the year when the weather is a little warmer.
Any ideas as to what would cause gauge cluster lights and the controls for the cruise lights to not work? All fuses check out good. I too have a 98 Ply grand Voyager. The circuit board checks good too, also each light bulb was tested and are good. Oh, all the rest of the dash lights work, not the gauge cluster.
PaullyBB Yeah thats a very common problem for that year van. and it wasnt corrected till the early 2000 vans. for ive seen these on 1996 to 1999 vans. Never on a 2000. whats happening is when these clusters were made the solder joints were poorly put together. Bad solder Batch, bad craftsmenship, i dont know for sure. But what happens is these joints crack over time. and render your cluster half or totally useless. if you take the cluster out, its not hard, and you pull the backing plate off the cluster I am willing to bet you can see broke joints with your own eyes. you can get creative and resolder the joints, or you can go to the junkyard or on ebay and check out the cost of a used one. I would try to get one from a 2000 van. just to let you know the chrysler town and country vans of that time came with cool white faced guages. and they look nice incase you want something different.
Thank you for this information. I just bought my 98 grand Caravan sport and apparently these lights have been flashing for two years. I did it exactly as you showed, but I don't get a solid light. I tried looking for more detailed information. My lights blink 1 (continuous rear wiper) Then six blinks (intermediate rear wiper) and it continues that code repeatedly any ideas on what it is i need to fix? Thank you.
rogerman25 it might be a malfunction of the HVAC control unit or a bad blend door motor. Its been soo long since Ive troubleshooted one of these vans. I would try it again, make sure the outside temp is right and make sure your heat and ac are working right
after a battery change the Hvac lights blink at me when i start the van.I did the calibration as video said and then turned the veh off and back on only to have the Hvac lights blinking at me again. what do you suggest?
Just bought a 97 voyager and all the lights are blinking. Cant try this till I get the serpentine belt replaced but the guy I bought it from said it had been doing this for years. Cant wait to try this. thank you
Is there any way to calibrate the blend door on a 1994 Town And Country? I get better heat while driving round a roundabout (ie turning hard left) Or might the actuator be broken? I get good heat from the rear system as it is pure mechanical, but very bad from the front system.
Bratfalken Its Vacuum and mechanical . sorry for the delayed reply. you probably have a cooling system issue. Check the fluid level and let me know it its low. Fill it if it is and drive it. it really sounds like its low
Bratfalken never runs hot or gurgles when you shut the car off, like theres a boiling pot of water under the hood?. Im leaning towards what you said about a bad actuator. ill look into it again get back to you.
It did gurgle and ran hot for a while. I'm leaning against a blown head gasket. It blew the hose between the thermostathouse and the waterpump last year. And the hose between the radiator and the thermostat housing this year. But as no water ends up in the oil I have pushed on as this car was mainly used just to go to and from work. Now at the annual security checkup it failed on several points and I have put it away until I decide weather to fix it or get rid of it. If it just was the things they found at the checkup I'd might fix it, but a blown headgasket could spell a lot of trouble if that is just the sympton of other problems.
First of all great video, very clear and concise. My question is, would this apply to a 2002 Caravan model as well. Even though my problem is slightly different. I get all the proper fan ops but I can only get heat on passenger side. My console does look like the one in your video. Am I looking at a vent door problem or an actuator? Thanks
Well, he is a great mechanic. He is just old school, and when it comes to things like resetting computers by button presses, not so much. He has no internet at all. Besides, I am not complaining. If he WERE trained to do it, he would do it and charge me for it like all other mechs out there. I would rather look it up, do it myself and save a few bucks.
I did the calibration but it ended up with the ac on light and the recirc. light both blinking on and off at the same time. Is my problem in AC system or with the Control module?
hi my 1998 Chrysler Town and Country lxi minivan does the light flashing on the ac part and after awhile of driving for like 10-20 minutes and with it turned on high it finally stops flashing and in able to turn them on and off but when I shut my van off and then turn it back on then it starts all over again now my question for you is after you do that hvac you did above in the video for the ac and it's donewhen you shut the van off and turn back on do they flash again ?
905speedgta what wrong with your new one? I love my 2000 red grand caravan it has 299,800 miles on it. Sorry to hear about your red grand caravan I know you probably loved it:(
905speedgta it's funny how we miss are cars after there gone, I had a 2008 grand caravan sxt with stow n go it was a newer design tho it had a 4.0 liter v6. I put that van to the floor and it almost put me in the back seat. Now I just a 2014 with a 3.6 and may have more horse power it definitely slower then 08 grand caravan. The 08 was lease so I traded it in at 32k miles:(
aohm7886 It doesnt feel like " MY OWN ". My red 1998 Caravan I did all that work to.. It was Grey interior i chaged that to Tan, I put all the stuff in it, it was my own creation...Im not too crazy about my 1999 to be totally honest. Its a non Infinity sound system, crapy front seats I cant even recline the drives seat for cuddle sessions lol.. and i havent even cleaned it since I bought it in april 2014. really, it just sits, and I only drive it when i need it.. It needs a whole front end I think, I know that the end links are GONE.. back shocks are shot..it has quad seating which i like, but it needs to be cleaned. and it needs to be worked on..maybe I should do that while I have the chance before It gets cold.. but then again....It just sits till i absolutly need it.. and I really dont care for it too much.. I have a 2007 sentra and a 2008 altima I just love
905speedgta I totally understand what you mean it doesn't feel like your own. It funny how we get attached to our cars. They begin being like your children and they give you unconditional love. I would try to find one like this one in this video. I like how you made it yours.
905speedgta, do you have a link for any error codes that are returned from the 2nd test you did? The rear wiper button & the intermittent button directly below display 2 codes . Top button flashes once, intermittent button flashes 3 times . then Top once, Intermittent 5 flashes 96 Grand Voyager, 3.3L
So your fix worked on my van but now the 2 wiper lights are blinking. Just so you know the ac unit on this van is gone. Is there a way to make the computer think the ac compressor is still connected?
I was having trouble with my 1997 Plymouth Voyager. My A/C works fine, but my heater won't get hot. First I checked my radiator fluid, it was fine. I ran my heater a while (until the car came up to normal running temp), then felt both hoses coming from and going to the heater core. They were both hot. I don't think it's my thermostat because the car is not overheating in any way. I then followed your instructions for recalibration of my HVAC system. Pressing the two lower buttons, the calibration began and went though it's check, but the two top buttons would not stop. The calibration will not complete. I turned the engine off and waited a while, then tried to start it up again, but the buttons continue to blink. I then tried to calibrate the actuator doors, even though they are working fine (I can adjust from full face to half and half to feet only to windshield with no problem). I then decided to just let it run hoping it would eventually finish and get to the top button only letting me know calibration is complete. After 15 minutes of waiting for it to complete, the two buttons on the top left side are still blinking. The middle button blinks 4 times, then stops, and the top button blinks once. Then the middle button blinks 4 times, then stops, and the top button blinks once again, repeating this pattern. I assume that means something isn't working correctly, but I don't know what it could be. Would you have any advice for me?
Thank you very much! I've tried it several times and I'm able to get to the wiper button flashing only but when I depress it the recirc & AC buttons start flashing again. It's also 70 degrees today. What is a blend door issue?
My heater won’t blow out hot air , I went through your modes to see if it would fix the problem, on the second one it worked it blew hot then cold air but after the process was done still no hot air , do you have any idea what’s wrong with it ?
What are the steps & button sequence to push for a 2005 Sebring Convertible with the Automatic Climate control? My heater core is definitely circulating hot water but I'm not getting any warm/hot air.
I have a 2000 Town & Country that low heat blows out on the the passengers side and the drivers side cold air blows out hard. I didn't have flashing lights or anything but the second part of the video showed the re-calibration of the blend doors so i gave it a try. Sadly it didn't help I never felt the cold air then hot air and the blinking lights never went off until I turned the van off : ( any more suggestions at what I could try?
Mary Gale sorry for the delayed reply. did you ever find a solution to your problem?> it cant be too cold when doing this.. does your ac system work? and did you cancel the program after the test compelted?
It was so long ago I don't remember. I will have my husband try it again. It was in storage for winter because of it blowing cold air on the drives side and I would of froze driving it.: ) I will let you know Thank you.
Hello, great instruction! Thanks! Does this calibrate the rear air actuators as well? I cannot get the rear to blow cold air or go to top vents. Thanks in advance! Have a super day!
all 4 of my lights are flashing when I turn the key on and when the 1 light starts flashing it flashes once then the 1 underneath it flashes in stages like it'll blink twice then 4 times then 8 times then when I hit that button all 4 of the lights start flashing. can you tell me if the switch is bad or I'm doing something wrong? thanks.
My 2000 Grand Voyager blows cold air thru out the whole van but when I need heat, it only blows on the passenger side and in the back of the van. Drivers side stays cold all the time. Can you give me any idea what to do?
That's what happened to me too. I had to replace the heater core (that is difficult, you have to dismantle everything to get at it and even then you have about 1/8" clearance between the core and the brake pedal bracket when sliding the core into the slot and trying to keep the foam rubber seal strip on!) and everything worked differently when I put it all together again. Previously the passenger side got no heat, now the left side gets no heat which is bad when you need defrost. I have the Dodge Shop Service Manual and it has the same procedure as 905 showed except that 905 started with the cool down test - pressing the AC/wash buttons - instead of the calibration/diagnostics test - pressing the wipe/wash buttons. I would think the calibration should come first, because if the modes are not correct it will affect airflow. Bottom line, I must have some defective components, namely the air door actuator for the left side or the body control computer or the temperature selector slide or ? I don't know how to test these components on the bench. The temperature selector is the easiest thing to reach, but how is it tested off the vehicle?.
You might have a bad blend door motor. this is pretty common on the 2001 to 2004 caravans. But even though it is heard of on the 1996 to 2000 model years its not as common. Is possible your HVAC controls are broken. Bring the car to a quiet spot. with just the key in the on position and the engine not running move the hot/cold switches. listen for the blend door motor you will be able to hear it. if you dont, chances are its not getting power, signal or a bad motor. let me kno what you find
I did the calibrations. The first one worked but the one using the wiper controls I get alternating blinking lights on the top two buttons. The top one blinks once and the second one down then blinks seven times. It keeps doing that and I don't get hot air just like warm. Any suggestions? Thanks
do you know how to calibrate fuel gauges misreading issues. mine sometimes when its about a quarter tank gauge will bounce down till fuel light comes on than next morning it will read empty once i drive around a little turn car off than restart light goes out and gauge reads quarter again. hard to get actual mileage.
Oliver G Oliver, That Sounds like a Bad Fuel Tank Sender Unit. These cars However are known for their Instrument Cluster Issues. TO where the Gauges go Haywire and bounce around or not work at all. Im willing to Bet you have a Bad Fuel Tank Sender Judging by what youve mentioned. Replacing it Involves Sliding down the gas tank. I would Bring it to the shop for Diagnosis. Unless you have a scan tool which will read live data and you are handy. Let us all know how it works out. I have quite a few Caravan Videos on my Channel, Check them out and Like and subscribe if you wish. Good luck
I'm having the problem of vents not switching. However, none of the HVAC lights come on and there is no response to holding the two buttons down. Is there another problem or way to get them to respond?
My A/C and Re-circulation lights were not flashing, but my directional controls were not working. I went through your procedure any way and then did the directional reset. the top 2 buttons for rear wipers never stopped flashing. I let them continue for an extra 6 minutes. Now I have no A/C. What do I do now!
I have a 2006 dodge caravan. 6 days ago the heat in front quit working. heat in rear is working. recirculate button flashes when i push it in. can I use this same technique. It is below zero in Wisconsin. Can I use the same technique on a 2006 model??
So I tried this and my 2 top windshield wiper indicates keep flashing back and forth and when I turn the car off all of them flash except the bottom one I'm wondering if it has something to do with my driver's side blend actuator needs replaced also I will mention that my ac doesn't work
Hi, My vents act as if they do not know where they are supposed to be set at, when I turn the vent nob it sounds like a CD player trying to read a badly scratched CD. Would the vent calibration fix that problem?
Hi I have a 99 caravan I recently out a new compressor and the clutch does not kick in I was told to add refrigerant which I did because the pressure sensor won't allow the clutch to engage unless it reads the required refrigerant in the system.my question is how can I add refrigerant to the system if I clutch does not engage
Thank you so much for your sharing how to calibrate, HVAC, and i want to ask if you have a , fuel injector for 1997 dodge crysler caravan, its hard to find some parts hera in our country i brought this van secondhand to my friend, because i drove this kind of van in my former employer so thats i like this for safety and very useful car
I have done all you have explained. The good news is that the top two lights has gone off. The bad news is the last two horizontal lights are still flashing. So what is wrong with my system and can it be fixed. I did this recalibration when the temperature outside is 95 degrees Fahrenheit. Plus the compressor didn't kick in like it should have.
dont have this same issue but i have a 1999 grand caravan ac and heat work in the rear from the bottom vents only, the overhead rear vents do not blow hot or cold could you help
I believe mine is failing on both calibrations. Just 2 of the lights blink off set and never stop unless the car is shut down. Overall things are working. Just the AC is not as cold. Id fully charged.
What needs to be done if it will not finish the test and the top two light continue to flash. It started after I left the key on over night and had to jump start. the weather is in the 70's now. when driving it will fix itself after about 15 min's. but all light s flash when started the next time. Thanks for the great video. Jim
Did the calibration and at the end the rear wiper intermittent button blinked several times and then it changed to the top one fir canceling the process. Any ideas why?
Great video. My dad's 2000 Chrysler Grand Voyager had this problem. Though it had no flashing lights, the AC was blowing out hot. He thought he needed a new slider switch. I noticed the compressor wasn't turning on yet it had a full charge of freon. So I went to Google and found this video. Thanks to this video, his AC is blowing out ice cubes today when it's 80° and he couldn't be happier. He has the single switch instead of the dual climate control but everything in the video worked the same. Excellent how-to. Thank you!
cobhc2448 Thankyou for your reply. Im here to help, I had alot of fun with these vans over the years. Ihave a few caravan videos on here , check out my Chennl and subscribe for new videos that im making. good luck with your van
If the ac and recirculation buttons persist in blinking after calibration then check and recharge the refrigerant. Easy to do with ~$30 cans with integrated pressure gauge and hose sold at WMart or auto stores. Worked for me today after multiple prior unsuccessful attempts to calibrate. AC works well again as a bonus!
Thank you I had to do this and your post worked for me.
I will do as you said...when it gets warmer. I still got the blinking two and under the hood, the compressor won't cycle or remain on when AC is off/on. No auto-store cans are gonna do the job...already tried. I gotta get the vac pump & manifold, do it right. I'll also replace both Schrader valves while I'm at it with new ones. Thanks, Stephen!
What's odd is when I first got my minivan running again, the AC system was empty but there were no blinking LEDs.
You Sir, are a gentleman and a scholar... Easiest a/c fix ever.
After 3+ years of flashing lights and being told my panel was shorted out…in five mins I was able to fix them! Thank you!
I see a Gen3 Chrysler minivan on occasion that does this. I shall do this with their vans, too.
The blend door sequence @ 4:23 fixed the no heat on drivers side--passenger side only blows heat- problem on my 97 Town and Country. Now heat works on both sides as it should 👍 The battery was recently replaced so that may have offset something. Happy it was a calibration issue. Many thanks to you for creating this video. Well done!
6:44 Mine won't recalibrate i've already gone through them the problem do you know
I have a 97. Base model front air No defroster on the rear. I bought another switch and it's doing the same thing
The light still flash on both switches
Thank You. It's 50 degrees here today, so I just did this and now it blows air out really well. Thank you.
Great video, I have had this problem as well and didn't know how to correct it, but I did notice that after driving for a while the lights would stop blinking. I have also had the issue with the air or heat strength. Thanks for posting this, it's been a great help.
Thank you so much for this quick and informative video. Fixed the blinking lights on 1998 Plymouth Grand Voyager. Note for others. The problem started after I tried to start the van when the battery was very low. The low battery voltage must have triggered an error in the computer or something. This fixed it quickly.
I did this procedure on my dads van after replacing the defective blend door actuator, but it wouldn't stop showing fault codes. So, then i decided to do a hard reset on the bcm/ ecm (disconnect the battery for ten seconds then reconnect) and then I ran the procedure again, this time it successfully calibrated. Thanks for posting this video, though. It was a great help!

Russ Newton Sometimes you can get away with pulling the ICM /IOD ( I cant remember which one its called and I may be mistaking this term for the 2001-2007 4th Gen vans. and you will Get the same result. What that does is it Resets the BCM. and Not the ECM. I dont like pulling he BAttery terminals unless I really have to, especially if the Inspection on the vehicle is very close to being up.

Explaining everything in my videos so someone whos ever done it before can. Thanks again, Be sure to subscribe to my Channel. I will be doing another Caravan video soon on one I am Junking
I just did this on my 2000 Dodge Caravan, and now the heater and defrosters works great. Thanks you save me a bundle of money.
Your Welcome Casey. Please if you will, subscribe to my channel. I have other caravan Videos. and I have a 1999 Dodge caravan I will be working on soon
Sure Will, mine is a 2000 LE AWD the wife loves it.
AWD were nice. I havent had the pleasure of working on one, But I hear they get So so gas milage.
Actually ours get an in town average of 19+ and out on the Interstate at 80 mph it will get 24 mpg. I am quite pleased with it.
How you make it? Mine would'nt work
The snow switch and the one beside it flashing all the time. Please help me
Thanks Bro, This works perfectly, You just saved me a trip to the shop, Last time this happened it cost me about 60 bucks at the dealership to get them turned off. Thanks again.
Can't thank you enough for doing this video. I had a evaporator & heater door actuator strip some gears because the system was out of sync.. I took the actuator apart and turned the stripped gears 180 because of the limited travel that they have and it worked. I then put the system thru the calibration and BINGO all is well.
Thank you!
Thank you so much. The lights on our '98 have been on for 4 years and we couldn't tell weather AC or Defrost was on or not. This worked like a charm!!
Well I did it, I've put gas into the radiator circuit and did the calibration, and the answer for my question is yes, the van must have refrigeration gas, and something that you don't told, the Windows must be closed... Thanks for the video it was very useful! :)
T.E.A Salvador A. Rea V. no it cant work, it needs to be able to operate with the ac system functioning.
I 'liked' this several weeks ago, not thinking that I would need it. However, after adding freon on a '98 T&C (That someone else had borrowed for a year.), I could feel cool air, but very little air flow. there were NO blinking lights, but I decided to try this procedure anyway. As it cycled through the steps, I got some great air flow! Now it seems to cool well!
I just tried this on my 1999 dgc, and so far it's working great, thank you for making this helpful video!
I have Chrysler Voyager 2.4 SE 1997, and still drive ...and I had this problem. Excellent video. Thank you ! Greetings from Croatia :)
awesome how to . dude you have great victim assistance skills and you dont focus on yourself but rather the patient , well done brother.
I have a 1998 Plymouth Grand Voyager and there's heat coming out the drivers side but not the passenger side. Will recalibrating the blend door help with this?
Excellent information and outcome. Probably the best info and outcome I have had to date. Many thanks.
This just got the passenger side a/C working in my in laws van this is great, thank you
my recycle and cold AC still blinking.... why and what do I do?
Same here... What did you wind up doing? Or what was the initial diagnosis if you took it to a shop?
Try to calibrate the blend door as well mine were both blinking and both turned off after
Adding freon solved this problem on my 97 Town and Country. I took it to an AC shop, they performed a procedure "recharging the AC system" what I was told. After that no more blinking lights, my AC was blowing out cold air through the vents. Hope this helps
Thanks buddy. This helped me alot. I didnt know why they were blinking in my 98. Now I'm trying to figure out why the blower fan is doing nothing
Taking care of this tonight! Just had AC charged and the lights are blinking. Mech told me he didn't know how to get them off! SMH.
I think I may just show him how its done.....the power of RUclips!
tried this and my lights are still blinking. what to do now?
I had this problem for two years and never could get the blend door test to finish. I tested my AC high and low with manifold gauges, condenser fans working good and the compressor clutch fine as well. Yesterday I turned the the heat all the way up and ran it until the evaporator got pretty warm. Then shut the car off turned the temperature selector to cold and in 30 seconds got the 20 degree drop on the evap core the blend doors moved all the way to cold and now I'm running 38 degrees and thos dang lights are off. Hope this helps someone fix their problem.
You are awesome,I never knew about this before, I was about to take apart the dash to look for a stuck blend door, because I was not getting heat and then I saw this video and I recalibrated and I now have heat, amazing thanks, why did the heat go off is the mystery,, but it now works,, maybe it had something to do with the blower which only works on high,, thanks for saving me a lot of trouble 👏👏
Thanks very much! You saved me a trip to the mechanic (and thus, saved me some money). Much appreciated!
Neil D no problem, thats what my channel is here for
Very helpful thank you! It is too cold to properly calibrate but i had no heat whatsoever and after doing the calibration procedure(though not calibrated correctly due to it being below freezing) I have heat again! Phew i thought i was going to have to tear my dash apart in the middle of winter to fix this problem. Thanks again!
your welcome.
this was great. fixed my problem in less than 10 minutes,probably saved big bucks !!!!
This worked!! Even though my problem was a little different... Blew hot all the time on driver... Also had lights blinking.. But Thanks.... It fixed it perfectly!
Felicitaciones desde México, Tamaulipas, Reynosa, muchas gracias funciono perfectamente, no dejes de subir vídeos por favor, gracias eres un profesional. Gran Voyager 1999, motor 3.8 L. Después de una falla con la pila se descalibro el sistema, desesperado busque y encontré tu vídeo gracias. Solucionado el problema.
Congratulations from Mexico , Tamaulipas , Reynosa, thank you very much worked perfectly , do not let upload videos please, thank you a professional. Grand Voyager 1999 , engine 3.8 L. After a fault with the system stack descalibro , desperate look and found your video thanks . Fixed issue .
Ok, so I tried this, about 7 times. What I'm getting is, when I push the A/C and the wiper wash buttons for the start of it, all the lights light up, but, the A/C and the recirc are the only two lights that keep blinking back and forth intermittently. None of the other lights light up after the initial start process. They go out and stay out throughout the entire cycle. After about two minutes or so of blinking, the A/C and recirc go back to blinking at the same time as each other. It won't go through the normal cycle like yours shows. The other calibration works. I would LOVE to find the problem and fix this.
I noticed the air wasn't as cold as it used to be, so I did the calibration and my lights started doing the same thing. I reset the memory by pulling the fuse, but the problem remains the same.
Mine is doing the EXACT SAME THING
Thank you so much for this video. I had no idea what was going on with my van.
nice of you for the help. got a question can I do the second step when the fan speed doesn't work properly it blows when it wants too, or should I replace the control. 99 caravan 4 cylinder 2.4L. thanks
Rito Venegas Sorry for the delayed reply. you should replace the fan motor or the resistor thats making it work when it wants to. do you know for sure if its the control??
905speedgta thanks for getting back to me, I replaced the a/c control panel and the recirc lights start blinking and no ac blowing plus now my fuel gauge, temp gauge, and other gauges don't work unless I unplug the new (used) panel. Also tried your steps and lights on the recirc just blink and don't function like your calibration video. one more thing the old controls didn't blink at all does that mean they were bad? get back at me plz.
Great video, I have read the repair manuals quite often regards to heater and A/C work and many other repairs but never saw this outlined, maybe its in the owners manual but never in all my years of owning this generation Caravan's have I read, seen or heard anything about this procedure.
Wow...how did you figure this out? You're a genius.
I have a 98 Grand Caravan - All the lights in that section are flashing - not just the recirculate and a/c.
Will be trying this and reporting back.
did that fix it for you? i have the same issue
Both of my lights end blinking all of the time when I do this of course I was having ac probs when I did it so I am wondering if it builds a memory??
I followed your instructions and the two lights for the a/c and recycle mode are still blinking. It is 72degrees here. So now what do I need to do?
VegasIsASavage TA mine is doing the same thing
Mine too what do I do
Hi, I have a question... In the video you say that the outside temperature must be warm, but what about the blown air? My voyager hasn't refrigeration gas inside the radiator circuits, could this calibration works without the gas?
Thanks this is great. I've just gotten a 98 Chrysler (UK) Grand Voyager with this very issue, although I'll have to wait until later in the year when the weather is a little warmer.
what if you do second test and both lights keep flashing?
ill second that
What if you do it seven times and they keep blinking?
Means they aren't working correctly. Like your a/c doesn't work. So it won't pass inspection
That Gamer Guy you don't need that to pass
Any ideas as to what would cause gauge cluster lights and the controls for the cruise lights to not work? All fuses check out good. I too have a 98 Ply grand Voyager. The circuit board checks good too, also each light bulb was tested and are good. Oh, all the rest of the dash lights work, not the gauge cluster.
PaullyBB Yeah thats a very common problem for that year van. and it wasnt corrected till the early 2000 vans. for ive seen these on 1996 to 1999 vans. Never on a 2000. whats happening is when these clusters were made the solder joints were poorly put together. Bad solder Batch, bad craftsmenship, i dont know for sure. But what happens is these joints crack over time. and render your cluster half or totally useless. if you take the cluster out, its not hard, and you pull the backing plate off the cluster I am willing to bet you can see broke joints with your own eyes. you can get creative and resolder the joints, or you can go to the junkyard or on ebay and check out the cost of a used one. I would try to get one from a 2000 van. just to let you know the chrysler town and country vans of that time came with cool white faced guages. and they look nice incase you want something different.
I got some good news it finally worked.. thank you thank you, you're a genius. :-)
aohm7886 no problem
Can you help me please,?
I have the to switch flashing all the time
jamal ali
Re run this test. let me know what happens
905speedgta both my recycle and ac cold is still blinking for awhile. what can I do?
905speedgta what if none of thr progaming works . Couldi be I got a bad clinment control ????
the HVAC Actuators in these cars are a common problem. Im glad you found your issue. Please subscribe for new caravan videos
Great instructions. I just had to use this video to help out a lady. Many thanks!
I fixed mine 2 years ago, thank you for the video.....
Thank you for this information. I just bought my 98 grand Caravan sport and apparently these lights have been flashing for two years. I did it exactly as you showed, but I don't get a solid light. I tried looking for more detailed information. My lights blink 1 (continuous rear wiper) Then six blinks (intermediate rear wiper) and it continues that code repeatedly any ideas on what it is i need to fix? Thank you.
rogerman25 it might be a malfunction of the HVAC control unit or a bad blend door motor. Its been soo long since Ive troubleshooted one of these vans. I would try it again, make sure the outside temp is right and make sure your heat and ac are working right
after a battery change the Hvac lights blink at me when i start the van.I did the calibration as video said and then turned the veh off and back on only to have the Hvac lights blinking at me again. what do you suggest?
Just bought a 97 voyager and all the lights are blinking. Cant try this till I get the serpentine belt replaced but the guy I bought it from said it had been doing this for years. Cant wait to try this. thank you
As soon as I clicked the blinking light when it finished calibration the two a/c light's are still blinking
Still blinking!
Great job and great service. You won't get that out of a manual..!! Thanks again..!!
Is there any way to calibrate the blend door on a 1994 Town And Country? I get better heat while driving round a roundabout (ie turning hard left) Or might the actuator be broken? I get good heat from the rear system as it is pure mechanical, but very bad from the front system.
Bratfalken Its Vacuum and mechanical . sorry for the delayed reply. you probably have a cooling system issue. Check the fluid level and let me know it its low. Fill it if it is and drive it. it really sounds like its low
Normal level all the time...
Bratfalken never runs hot or gurgles when you shut the car off, like theres a boiling pot of water under the hood?. Im leaning towards what you said about a bad actuator. ill look into it again get back to you.
It did gurgle and ran hot for a while. I'm leaning against a blown head gasket. It blew the hose between the thermostathouse and the waterpump last year. And the hose between the radiator and the thermostat housing this year. But as no water ends up in the oil I have pushed on as this car was mainly used just to go to and from work. Now at the annual security checkup it failed on several points and I have put it away until I decide weather to fix it or get rid of it. If it just was the things they found at the checkup I'd might fix it, but a blown headgasket could spell a lot of trouble if that is just the sympton of other problems.
Thank you very much. I was wondering why those lights were going on and off. Thank you once again.
First of all great video, very clear and concise. My question is, would this apply to a 2002 Caravan model as well. Even though my problem is slightly different. I get all the proper fan ops but I can only get heat on passenger side. My console does look like the one in your video. Am I looking at a vent door problem or an actuator? Thanks
Well, he is a great mechanic. He is just old school, and when it comes to things like resetting computers by button presses, not so much. He has no internet at all. Besides, I am not complaining. If he WERE trained to do it, he would do it and charge me for it like all other mechs out there. I would rather look it up, do it myself and save a few bucks.
Thank you so much , never knew this, you have been a great help .
willy where are you located? whats the temp outside. these cannot calibrate correctly in cold temperatures. my may have a faulty unit
I've tried this but the 2 back window wipers just continues to blink.....
Do you recommended any further steps I can take???
I did the calibration but it ended up with the ac on light and the recirc. light both blinking on and off at the same time. Is my problem in AC system or with the Control module?
hi my 1998 Chrysler Town and Country lxi minivan does the light flashing on the ac part and after awhile of driving for like 10-20 minutes and with it turned on high it finally stops flashing and in able to turn them on and off but when I shut my van off and then turn it back on then it starts all over again now my question for you is after you do that hvac you did above in the video for the ac and it's donewhen you shut the van off and turn back on do they flash again ?
Do you still have this van? Even tho it had some rust on it still was a nice looking van:)
asth84 I dont, I have a 1999 Dodge Grand Caravan in blue now..I hate it. miss my van so much
905speedgta what wrong with your new one? I love my 2000 red grand caravan it has 299,800 miles on it. Sorry to hear about your red grand caravan I know you probably loved it:(
905speedgta it's funny how we miss are cars after there gone, I had a 2008 grand caravan sxt with stow n go it was a newer design tho it had a 4.0 liter v6. I put that van to the floor and it almost put me in the back seat. Now I just a 2014 with a 3.6 and may have more horse power it definitely slower then 08 grand caravan. The 08 was lease so I traded it in at 32k miles:(
aohm7886 It doesnt feel like " MY OWN ". My red 1998 Caravan I did all that work to.. It was Grey interior i chaged that to Tan, I put all the stuff in it, it was my own creation...Im not too crazy about my 1999 to be totally honest. Its a non Infinity sound system, crapy front seats I cant even recline the drives seat for cuddle sessions lol.. and i havent even cleaned it since I bought it in april 2014. really, it just sits, and I only drive it when i need it.. It needs a whole front end I think, I know that the end links are GONE.. back shocks are shot..it has quad seating which i like, but it needs to be cleaned. and it needs to be worked on..maybe I should do that while I have the chance before It gets cold.. but then again....It just sits till i absolutly need it.. and I really dont care for it too much.. I have a 2007 sentra and a 2008 altima I just love
905speedgta I totally understand what you mean it doesn't feel like your own. It funny how we get attached to our cars. They begin being like your children and they give you unconditional love. I would try to find one like this one in this video. I like how you made it yours.
905speedgta, do you have a link for any error codes that are returned from the 2nd test you did?
The rear wiper button & the intermittent button directly below display 2 codes . Top button flashes once, intermittent button flashes 3 times . then Top once, Intermittent 5 flashes
96 Grand Voyager, 3.3L
run the test again, and let me know your results.
Look up grand voyager climate control fault codes on google. Alpar forum has a fault code reference chart.
Thank you!!! This was exactly what I needed. I live the step by step instructions. It fixed the issue. Thanks again!!!!
So your fix worked on my van but now the 2 wiper lights are blinking. Just so you know the ac unit on this van is gone. Is there a way to make the computer think the ac compressor is still connected?
I was having trouble with my 1997 Plymouth Voyager. My A/C works fine, but my heater won't get hot. First I checked my radiator fluid, it was fine. I ran my heater a while (until the car came up to normal running temp), then felt both hoses coming from and going to the heater core. They were both hot. I don't think it's my thermostat because the car is not overheating in any way. I then followed your instructions for recalibration of my HVAC system. Pressing the two lower buttons, the calibration began and went though it's check, but the two top buttons would not stop. The calibration will not complete. I turned the engine off and waited a while, then tried to start it up again, but the buttons continue to blink. I then tried to calibrate the actuator doors, even though they are working fine (I can adjust from full face to half and half to feet only to windshield with no problem). I then decided to just let it run hoping it would eventually finish and get to the top button only letting me know calibration is complete. After 15 minutes of waiting for it to complete, the two buttons on the top left side are still blinking. The middle button blinks 4 times, then stops, and the top button blinks once. Then the middle button blinks 4 times, then stops, and the top button blinks once again, repeating this pattern. I assume that means something isn't working correctly, but I don't know what it could be. Would you have any advice for me?
Thank you very much! I've tried it several times and I'm able to get to the wiper button flashing only but when I depress it the recirc & AC buttons start flashing again. It's also 70 degrees today. What is a blend door issue?
My heater won’t blow out hot air , I went through your modes to see if it would fix the problem, on the second one it worked it blew hot then cold air but after the process was done still no hot air , do you have any idea what’s wrong with it ?
What are the steps & button sequence to push for a 2005 Sebring Convertible with the Automatic Climate control? My heater core is definitely circulating hot water but I'm not getting any warm/hot air.
I have a 2000 Town & Country that low heat blows out on the the passengers side and the drivers side cold air blows out hard. I didn't have flashing lights or anything but the second part of the video showed the re-calibration of the blend doors so i gave it a try. Sadly it didn't help I never felt the cold air then hot air and the blinking lights never went off until I turned the van off : ( any more suggestions at what I could try?
Mary Gale sorry for the delayed reply. did you ever find a solution to your problem?> it cant be too cold when doing this.. does your ac system work? and did you cancel the program after the test compelted?
It was so long ago I don't remember. I will have my husband try it again. It was in storage for winter because of it blowing cold air on the drives side and I would of froze driving it.: )
I will let you know
Thank you.
Hello, great instruction! Thanks! Does this calibrate the rear air actuators as well? I cannot get the rear to blow cold air or go to top vents. Thanks in advance! Have a super day!
all 4 of my lights are flashing when I turn the key on and when the 1 light starts flashing it flashes once then the 1 underneath it flashes in stages like it'll blink twice then 4 times then 8 times then when I hit that button all 4 of the lights start flashing. can you tell me if the switch is bad or I'm doing something wrong? thanks.
My 2000 Grand Voyager blows cold air thru out the whole van but when I need heat, it only blows on the passenger side and in the back of the van. Drivers side stays cold all the time. Can you give me any idea what to do?
That's what happened to me too. I had to replace the heater core (that is difficult, you have to dismantle everything to get at it and even then you have about 1/8" clearance between the core and the brake pedal bracket when sliding the core into the slot and trying to keep the foam rubber seal strip on!) and everything worked differently when I put it all together again.
Previously the passenger side got no heat, now the left side gets no heat which is bad when you need defrost.
I have the Dodge Shop Service Manual and it has the same procedure as 905 showed except that 905 started with the cool down test - pressing the AC/wash buttons - instead of the calibration/diagnostics test - pressing the wipe/wash buttons. I would think the calibration should come first, because if the modes are not correct it will affect airflow.
Bottom line, I must have some defective components, namely the air door actuator for the left side or the body control computer or the temperature selector slide or ? I don't know how to test these components on the bench. The temperature selector is the easiest thing to reach, but how is it tested off the vehicle?.
You might have a bad blend door motor. this is pretty common on the 2001 to 2004 caravans. But even though it is heard of on the 1996 to 2000 model years its not as common. Is possible your HVAC controls are broken. Bring the car to a quiet spot. with just the key in the on position and the engine not running move the hot/cold switches. listen for the blend door motor you will be able to hear it. if you dont, chances are its not getting power, signal or a bad motor. let me kno what you find
My cold feet love and thank you! Re-calibrated the blend doors and now I have heat at my feet again.
Brother thank you.... Funny how hard it was to find this info.
I did the calibrations. The first one worked but the one using the wiper controls I get alternating blinking lights on the top two buttons. The top one blinks once and the second one down then blinks seven times. It keeps doing that and I don't get hot air just like warm. Any suggestions?
Thanks
do you know how to calibrate fuel gauges misreading issues. mine sometimes when its about a quarter tank gauge will bounce down till fuel light comes on than next morning it will read empty once i drive around a little turn car off than restart light goes out and gauge reads quarter again. hard to get actual mileage.
Oliver G Oliver, That Sounds like a Bad Fuel Tank Sender Unit. These cars However are known for their Instrument Cluster Issues. TO where the Gauges go Haywire and bounce around or not work at all.
Im willing to Bet you have a Bad Fuel Tank Sender Judging by what youve mentioned. Replacing it Involves Sliding down the gas tank. I would Bring it to the shop for Diagnosis. Unless you have a scan tool which will read live data and you are handy. Let us all know how it works out. I have quite a few Caravan Videos on my Channel, Check them out and Like and subscribe if you wish. Good luck
thanks alot will do that
Oliver G Just following up with your question froma few months ago. How did you make out with the Fuel Readings being off?> was it the Sender unit?.
I'm having the problem of vents not switching. However, none of the HVAC lights come on and there is no response to holding the two buttons down. Is there another problem or way to get them to respond?
yeah my van had the same issue. I hope we get a response
I tried to do this but unfortunately it didn't work all of the lights didn't flash, what else can I do to fix the problem?
My A/C and Re-circulation lights were not flashing, but my directional controls were not working. I went through your procedure any way and then did the directional reset. the top 2 buttons for rear wipers never stopped flashing. I let them continue for an extra 6 minutes. Now I have no A/C. What do I do now!
I have a 2000 Dodge Grand Caravan sport had no heat so decided to try this and it worked I have heat haven't had heat for a few days
this is pure knowledge and super awesome
I have a 2006 dodge caravan. 6 days ago the heat in front quit working. heat in rear is working. recirculate button flashes when i push it in. can I use this same technique. It is below zero in Wisconsin. Can I use the same technique on a 2006 model??
So I tried this and my 2 top windshield wiper indicates keep flashing back and forth and when I turn the car off all of them flash except the bottom one I'm wondering if it has something to do with my driver's side blend actuator needs replaced also I will mention that my ac doesn't work
Hi, My vents act as if they do not know where they are supposed to be set at, when I turn the vent nob it sounds like a CD player trying to read a badly scratched CD. Would the vent calibration fix that problem?
I just replace a radiator fan relay do I have to reset the computer because the cooling fan isn't working. It's a pleasure to watch your videos.
Hi I have a 99 caravan I recently out a new compressor and the clutch does not kick in I was told to add refrigerant which I did because the pressure sensor won't allow the clutch to engage unless it reads the required refrigerant in the system.my question is how can I add refrigerant to the system if I clutch does not engage
Just add the refrigerant and the clutch will turn on when it gets to the point that makes it engage...
I just bought a used caravan . I cannot get the heater to work at all. Is there something to do to reset it ?
Thanks! Haven't had that particular problem yet, but great info to have in the bank.
Worked like a charm for me! Thanks!
Thank you so much for your sharing how to calibrate, HVAC, and i want to ask if you have a , fuel injector for 1997 dodge crysler caravan, its hard to find some parts hera in our country i brought this van secondhand to my friend, because i drove this kind of van in my former employer so thats i like this for safety and very useful car
I have done all you have explained. The good news is that the top two lights has gone off. The bad news is the last two horizontal lights are still flashing. So what is wrong with my system and can it be fixed. I did this recalibration when the temperature outside is 95 degrees Fahrenheit. Plus the compressor didn't kick in like it should have.
What does it mean if all hvac controls and rear wiper and defrost blink all the time
dont have this same issue but i have a 1999 grand caravan ac and heat work in the rear from the bottom vents only, the overhead rear vents do not blow hot or cold could you help
I believe mine is failing on both calibrations. Just 2 of the lights blink off set and never stop unless the car is shut down. Overall things are working. Just the AC is not as cold. Id fully charged.
Is this also suitable for a 1997 GS AWD 3.8L? Thanks for an answer🙂
What needs to be done if it will not finish the test and the top two light continue to flash. It started after I left the key on over night and had to jump start. the weather is in the 70's now. when driving it will fix itself after about 15 min's. but all light s flash when started the next time. Thanks for the great video. Jim
Did the calibration and at the end the rear wiper intermittent button blinked several times and then it changed to the top one fir canceling the process. Any ideas why?
Thank you tried it and I am impresséd thank you so much for a minute there I thought something was wrong with my rear cabin blowers
