It might not be much, but you have my eternal gratitude. I was able to find (and replace) the relay and now my car doesn't overheat anymore.
Thanks to you, I was able to get my radiator fans working again by replacing the relay for only $50 versus the hundreds they would have charged me at the mechanics for the full diagnosis, parts, and labor.
Mine work for 1 week now my fank keep spinning even engine off
worked like a champ - thank you. when the jumper wire started the fans, i was very happy.
This was very helpful. I didn't know that existed. I replaced that part and it worked. Thanks
I've had 3 of these so far. A 96, a 2000, & just bought a 2003 2 days ago. The first 2, I wired the fans up on toggle switches 😂😂 to be manually operated. I'm going to follow these step by step instructions & maybe I can actually fix #3 correctly 😂😂😂😂. Due to your educational tutorial, & how in depth you actually went, I also subbed. Love the manner in wich you teach. Felt like I was back in college again 😂😂. That direct eye contact, even to the camera, is the key. Thats old school right there. You know what I mean? Thanks for uploading.
VERY INFORMATIVE VIDEO , I NOTICED HOWEVER THAT YOU ONLY BLINKED TWICE DURING YOUR WHOLE PRESENTATION....YOU MUST HAVE INCREDIBLE FOCUS AND CONCENTRATION!
LOL!!
heres another non blinker.
this ones scary though

i guess I am pretty randomly asking but do anybody know of a good site to watch newly released movies online?
@Giovanni Huxley i would suggest Flixzone. Just google for it :)
Thanks for the video, fixed my problem with my 06 town and country!
Hey car doctor you videos always help me out this one mainly helped me very much .. thank you very much
Thank you for the video, fixed my problem in minutes!
Excellent!
That was very well done.
I'm going to check the relay signal now
thank you so much, you helped me figure out what was wrong with my van, and I was able to fix it 😀
Thanks for this helpful video, Doc ! I'm going to replace this component soon. Cost is $41.00, including shipping.
I gonna run a toggle switch and operate mine manually.
my issue, exactly, not sure if fan or relay or something else yet till i go out there and give it a look, but thanks alot for the help
!
Great VID for DIY ers. THANKS !!
@4:30, nice dragonfly! :) thanks for the info!
Thanks for the great info.
Your video is heavensent. Saved me $ by checking fuse.
Thank you for sharing your knowledge sir 👊
Great video! Question: Will the coolant temp gauge on the i.p. malfunction if the fan controller is bad (while the fans don't work, but the ect senor shows good readings, and the fans run w/the the scan tool activation test)?
Very good example that’s
Was very helpful 🤟🏼
Gracias, Car Doc. Now i know I'm taking my buggy to the local mechanic. At least I'll know what's going on.
This video really help me thanks man
Glad it helped. Thank you for dropping by.
Just wanted to say thank you!
Thanks for your video ...nice work
Great video . Just bought a 04 grand caravan tonight for 200 bucks runs and drives but the fans aren't working and I just replaced a simple coil pack which fixed my the issue why they sold it so cheap. Gonna fix this old van up and try to get 1500 out of it
Thank you great explanation Keep it up
Thanks for the information. This fan relay definitely needs replacing on my 2001 Caravan because it has corroded so much the rivet end area of it broke off due to aluminum rot & I am also getting the proper CEL error code. However, I am not getting the constant 12V from the 40A fuse to the fan relay's Orange wire connection. The fuse is OK & the fuse's right side connection terminal on the underside plug has continuity from the fuse socket to the Orange wire. The Orange fan relay wire looks healthy (not discolored or hardened from being overheated) at the connector under the fuse box. Is there a junction box or a multi-pin connector between the 40A fuse terminal socket & the fan relay socket where oxidation may have occurred causing continuity loss? I could jumper a bypass wire directly from the underside fuse terminal to the relay socket but I prefer to fix it the correct way. I have a Chilton manual but it is very lacking in detail about the wiring harness. I used to repair electronics for a living so I am experienced with bad connections & wiring repairs. I can't afford the shop manual. Thanks in advance for any advice from anyone.
great video.thanx for the help.
Jesse the car guy ventura.... Great video tks.
Thank you very much for the great video. Will give it a go.
Yeah, make sure to check the screw. I replaced mine 2 years ago. It began having issues. Limped it home checked the relay and it felt loose. I forced a larger screw in and the fans kicked on so it was a ground issue with the screw . Guess over time it loosened plus a bit of corrosion and the connect wasn't good at times.
thank you very much car doctor for helping me God bless you
thanks for this video, it was great except that I needed to know specifically how to remove the fans. one of the bearings wore out. it sounded like it was going to explode. RSVP as I need this vehicle on the road by monday. Thanks,
Jim
I forgot to tell you that my vehicle is a 2007 Dodge Grand Caravan.
Pretty simple, if you simply look at it.
I like this guys so I had to subscribe. Thanks.
explained perfectly!

Thanks for posting this video. I had the same problem - P0480, radiator cooling fans won't come on. My 40 amp fuse was OK. I replaced the fan control relay and that solved the problem! My vehicle is was manufactured in May 2007 and now it is early 2017 so that relay lasted almost 10 years.
Thanks for the video !! Good ! Having a huge problem with Plymouth Voyager 1998, 2.5 litre engine, radiator cooling fans = 2, don't go on = car overheats in stop and go traffic, of course!?? Had a van in a garage, where they "screwed" everything up, they even did oil change, and when car was returned, there was no oil??? Forgot to put some in?? They suppose to flash cooling system, they fucked up drain plug, plastic, and car , of course was leaking coolant, plug was half open, I fixed that, put new plug in there! Anyway, they did change cooling fan resistor/ relay, actually they did change it, I checked that, but now cooling fans don't go on at all?? I did replace cooling temperature sensor, no help?? Tried to check, if they fucked up the wireing in cooling fan harness, they changed that too, can't really tell, seems fine?? Power on outside, other big wire next to it, ground on the other side, and signal wire next to it?? Is that correct?? Did replace fan assembly, fans work, of course, when you give 12 V on them?? Can't make signal to put fans on?? When turning AC on, which works fine, no fans?? And even engine warms up, no fans?? What could be wrong, I tested cooling fan sensor, which they replaced, seems still fine, did resistance test, neg. on left side and pos. on a middle and there is resistance, like .550 Ohms??? Bad one would be no resistance, am I right?? Please, help me , took a picture from new wireing, from harness, if you need that, I put it in here!!! Did they screw up wireing, or what ??? Thanks, and thanks for all your videos, very helpful =) PS. PCM can't be burned out, car works fine otherwise......;o)
Thanks for the info
hoping you can help @The Car Doctor i have an 05 chrystler pacifica. Radiator fans not turning on. i checked the pigtails and are in fact receiving power as i should. I replaced the relay and still no go.
Thank you, you made me 30 bucks watching this video.
Please send check...hehe
Informative, thank you Car Doctor, but didn't quite help me because the fan relay sensor looks different than mine and is located in a different spot on my 1998 Dodge Caravan (Sport). I did manage, however, to find MY van's relay sensor and replace it but it was a HUUUUGE pain bcuz it's mounted to a wall beneath the air box and air filter! The fans worked fine for a while but have stopped coming on while I'm driving. Engine doesn't overheat unless I'm in our horrible stop-and-go Seattle traffic or if I try to turn the A/C on. I'll need to figure out how to test the cooling fan motors to see if that's the issue or it could be that the thermostat is malfunctioning.
Appreciate it. I thought it was my thermostat.
Thanks for the TIP
thanks for your help
So you turn fans on threw the rely not just the fans? I saw some one start fans with putting power on the motors. Carquest gave me a different part number. R0323 how crazy. I sure hate working on this in 110 heat we are dieing. In AZ .
Is there a way to test relay once you have it off vehicle?
Thank you very much
I think my computer modular unit doesn't work. Fans and relay is good. How do I give direct power/bypass to radiator fans. Appreciate your help.
Thank you 🇺🇸
Hey car doctor, I've replaced the fan relay and the fan turns on and works fine when I'm driving. But when I get stuck in traffic the temperature goes up again and the fans stop working again.
Nice bright shop you have there and good size, sounds like you work alone in there.
camshaftP16 thanks, it's a newer building with nice lights. For now it's just me and the wife at the shop but I have had employees over the years. Its sure nice having the space to stage cars and work on more than one at a time while waiting for parts. Thanks for watching my videos.
Thanks for the video. It helped me narrow some stuff down. I have a 2007 with the symptoms you described. When I jumper the orange hot wire and the wire to the fans both fans work. But when I hook everything up and the engine heats up, only the left side fan comes on. The right side fan never does. I was told that the right side fan only came on at highway speed and when the A/C was on. Is there any truth to that, or should they both be running at the same time? It doesn't appear the wire to the right side fan goes directly to the radiator relay.
The right does come on with A/C but not necessarily when on highway.
Thanx for the tutorial 👍
Im having and issue, I noticed the temp needle on my panel was on 3/4, (once running it always stays static just shy of half way). So, I popped the hood and noticed the right fan wasnt working. The needle eventually went back to the middle. I've checked several times and the fan wont turn on despite the temperature. Im guessing it is a fried motor?
Same thing is happening to me was it youre fan motor ?
@@MrRobchavez Yes, took it to a electrical mechanic. He unplugged the connector and the volts were idle. I managed to get a replacement motor at a junkyard, but it failed within 8-10 months. Had to buy the complete housing this time. Also, the thermostat was rusted, not sure if it had something to do with frying 2 fan motors.
I’ve got one fan spinning and one fan not, though it moves freely when I move it by fan. Can I jump straight to replacing just the radiator fan without testing the wiring and all that?
What if it's fine during normal stop and go driving but radiator only over heats when AC is on?
If both fans are separate units would it have two relays or does one run both...
Thank you
+Radu Blaga No problem, hope it helped. Thanks for watching
It sure would be good to see the temp sensor value displayed on a scan tool in data mode. It's possible there are stored codes related to temp sensor or fan operation in the PCM. Try checking the codes at an auto parts store that does that and also try clearing the codes.
Well done video. I was able to walk straight through the entire process but replacement of the fan relay did not work. (06 Pacifica) I tested all four wires at the relay and all work as expected except not getting the intermittent signal on the fourth wire to trigger the fans. Both fans do work fine when bypassed. Temp gauge staying in mid range even when getting hot while idling. I assume this is either an issue with the temp coolant sensor or worst case pcm. For $10, I am going to try to change the coolant sensor first. Anything else I might be missing as the culprit?
Did the cooling sensor fix the issue?
Did the coolant fix your issue?
I did all this testing prior to seeing this video. I wasted money on a new relay and mine is still no good. I got two fans and a/c. Turn on the A/C and the fans do not come on. The ground wire to the relay is good, the 40a orange wire is good. jumpered the two large terminals and the fans do come on. Only thing I suspect is the wire coming from the PCM is not sending the signal to the relay or the PCM is not doing its job. I looked to where the PCM is located and it just looks like a nightmare to try and get at it and have a chance in hell of trying to ohm out the wire to the relay. I'd at least like to narrow it down to whether its the wire/connection or the PCM. Pretty annoying considering this 2005 van only has 130,000km on the odometer.
drivers side cooling fan dose not turn on at all would this also be a relay problem?
I need help ..i have an 09 dodge gran caravan and i cant find the cooling fan relay please help...thanks
I got a 07 T&C. I can turn the fans on with my scanner. They will NOT come on with AC. And they never come on when just idling. Scanner pid will hit 210 and it will just start pushing out the radiator unless i turn fans on with scanner. Also temp gauge never goes about 1/2 mark?
2006 Dodge Grand Caravan {P0135 O2 Sensor 1/1 Heater Performance}. Driver side Fan Blade broke down & Ac water was leaking making Carpet wet inside of van (both Side Driver & Passenger). Replaced Radiator & Fan blade. Turned on AC- Passenger side Fan comes On but not the Driver side. Whats the Solution if you can help. Thanks
I have a 98 dodge grand caravan sport 3.3L, I drive it on the back roads and the needle barely moves up to Hot, I go on the freeway for about 8 miles, the needle is dangerously close to Hot. I just put coolant/antifreeze in the radiator, however, the engine coolant reservoir looks a little low, is that the problem?
Possibly. When the engine is cold fill the radiator and the reservoir. If its low and the problem is fixed you should check for leakage. Most times its the water pump.
My fans only come on when ac is turn on. I jump the wire from resistor relay but engine shake so I didn't had time to check if the fan was spinning bc I got frightened. Any ideas if I should jump it again and check if it spin? I have a dodge caliber .
Is there another way to manually run the fans for testing?
hi i have a 07 town n country van..3.3 engine my fans are running constantly and i have a po 117 code that i cannot erase..i have replaced temp sending unit.no change..do i have a short somewhere,,?..or could i change out this relay...?...i have checked power to the temp sending unit..no voltage.. however l notice both wires are shorted to ground...so what do i search for..? any help is appreciated..
99 dodge grand caravan 3.3l temp gauge works with key on but not while running. New thermostat and sensor next to it. All fuses good. Not airbound. Tried removing thermostat n still nothing. Sensor Voltage is 2.5 with key on and 4.0 while running. Fans don't come on unless you unplug the temp sensor. Any ideas?
Does the 2013 town & country have the same system? My daughters van is doing this, overheating at idle and the fan is not coming on.
Hey Sir is the 2013 model the same, i cant find that relay, there is one in the fuse box and a 30A fuse but cant find anything else
What causes the cooling fan relay to continuously go out I had to replace my twice in the last 3 years
On early years the relay is under the drivers side head light under a black plastic box, then 200 and up under the air box attached to the frame. Remove the air box and look straight down. Sometimes both fans don't turn on until you turn on the a/c. Also check out ruclips.net/video/AdIYm9kM5E0/видео.html on how to test that last wire coming from the van computer if replacing the bad relay doesn't work.
Good Information thanks. but if you point the camera on job , then we can learn more.
Hey Doc, the fans work, the relay is new, but the right fan does not click on when the A/C is on..computer? Thanks!
I'M CURRENTLY HAVING THE SAME PROBLEM WITH MY VAN.
Yup I replaced the relay with a brand new one fan still not working now I think it's wiring harness or something
I am not getting 12V on the orange wire (using the battery Neg for a ground). The fan relay fuse is good & I am getting 12V at the fuse terminal. Both fans are good & I have temporarily connected one of them directly to the battery with an inline switch just in case I need to turn it on to cool the engine if I get stuck in traffic. The fan relay aluminum heat sink was very corroded on the riveted side which crumbled and broke off when I moved it. I am waiting for a Chilton's manual to come in a few days. In the meantime I am using a troubleshooting guide that covers this fan relay at a blog called 'The Supreme Pundit' (I am not affiliated with them). Thanks in advance for any suggestions
While sitting in traffic, how can you tell if the fan comes on? Sould you be able to hear it?
My fan is turning on thou and my temp is slightly over the middle no coolant loss or leaking or no check engine lights on I can't figure it out
thx man saved me a bunch of time. can I send you a donation?
Yup I gotta 2000 Caravan with the fans not working. They were working and not shutting off. I disconnected the battery and then reconnected the battery and the fans were off. I started up the engine but did not try the AC. Next day the battery was dead. I charged the battery and when I started the engine and put on the AC the fans did not turn on. In the evening I disconnected the connector to the temp sensor and the next day the battery was good. I replace the temp sensor but that was not the fix but the battery did not discharge. I replaced the fuse but when I checked the fuse with my volt meter it was good. I also replaced the fan relay. Mine was mounted on the frame. The fans are good as I disconnected the fans and jumped them to the battery. So I guess I have an open wire or a bad control module. I will have to try what you did here and use a test light then jumper the two leads.
I guess if I don't have 12 volts on the orange I need to find a schematic and trace it back to the module. Thanks for this video. Gonna see if I can get it online from my library.
I have Chrysler T & C Touring 2006. The Fan on driver side isn't working, but the fan on passenger is working. That why the engine got hot all around. But no overheat. Do you think I have to replace both fans together? Thanks.
You'll need to do some testing.
Thanks
Hey I think I'm going to have to replace the radiator in my wife's T&C. The transmission cooler is no longer part of the radiator is that correct? I did a pressure test and started losing fluid but before I could find where it was coming from it stopped. I replaced some of the fluid and tested again but didn't see any fluid on the ground. Gotta go use the mother in law's garage as the ground is a little cold right now on my back. How do you tell the difference between a standard and a heavy duty radiator? thanks Tim.
I wish I could help. I think your right about the cooler being separate. I would call the dealer parts guy with the Vin and get a part number for the radiator then cross it into an aftermarket number. Be sure to look at the pump since they are the biggest source of leakage.
Yeah I'll pump up the pressure and get under there with my umbrella and sea what I can see. Hey I didn't check the cap and I think where the overflow comes down is where there was fluid. Thanks four4 fore for getting back so quick. Have a great day.
if my dodge 06 minivan has a cracked block,is it a total loss????let me know
what if the jumper wires dont turn the fans on? i just put brand new fans in after the radiator exploded i put a new radiator in as well 2003 chrysler voyager
Mine was relay 1999 with 235,000 miles , easy fix..
Mine has 225,000 and I hooked the checker to the computer and the code came out as 1491, that about right ... So if I replace the relay it will go off ?
Is there any way to ohm out the relay and test it?
the problem i have is with the plug ! keeps melting the black cable ..any of this plugs comes with ceramic insulation ? it will resist more heat ( tested for amps withdrawl and is on 20 amps )..to much, just to crank those electric fans thus melting of the plug !!
2005 Dodge Caravan Radiator Fan Driver Side is not working. Passenger side is working pretty but not the Driver side. What should I do.
I have a 2000 Chrysler T&C 3.8 liter engine. The radiator fan is working but it makes a loud squealing noise (maybe bad fan ball bearings?) I am not overheating and have no codes. Can it be the fan relay or the radiator fan? Please help
question for you on a 2007 Dodge Caravan I have the passenger side fan when it comes on clicks. I'm going to replace the fan assembly but I was curious should both of these fans be running all the time? because I noticed the fan on the driver side running and the fan on the passenger side goes off and on at various times.
No they don't usually both run all the time. They will cycle when the A/C is on.
+The Car Doctor I saw that happen as you said when I replaced the fan assembly yesterday! At first when I started the vehicle they did not run as it got warmer I turned on the AC and both fans kicked on at the same time. after investigating the older fan assembly I noticed one of the fans turned really hard and clicked. that must have been the problem. would you be able to help me with one more question I've asked around and I'm not getting a straight forward answer. I lost some antifreeze because I had to remove the top hose the manual says to only use hoat antifreeze. what if the previous owner of this vehicle used let's say Prestone? if I go out and buy some hoat g05 zerex and added to the existing antifreeze will it cause any problems? you just never know what the previous owner put in there. from the color of the antifreeze it looks red if you put a piece of paper in it and pull it out it's pink on the paper but I'm sure the color doesn't really help me to diagnose what is in the vehicle currently. I have an 07 Dodge Caravan thank you
That should be Chrysler 5 year coolant. You could add G05 but I would just get the Chrysler coolant if available.
+The Car Doctor ok thank you. I suppose i should flush the whole system then and replace.
Well it sounds like it has the Chrysler coolant in it. Should be pinkish in color.
I have a 2000 caravan. the radiator fan is not working but I have 12v positive coming out of the relay.
Should both fans be running 100% of the time?
relays without fins need thermal grease paste under them to keep them cool.
I have a 2002 jeep liberty and my a/c hasn't been working for a while and i never knew why. But recently my check battery light came one and my abs light flashed at me a couple time ( my check engine light is usually on because my gas cap is the wrong size) and my car would just stop using electricity or something ( the radio stopped a couple time and when i would turn the car off i would need a jump because it wouldn't turn back on. i just went to napa and got a new battery thinking thats what it was but my check battery light still comes on along with my engine light. So i took it to autozone and they said my cooling fan motor relay was malfunctioning. I was just wondering if this broken relay explains why my last battery drained so fast and why my abs light flashed.
Might cause a battery drain but don't think it would effect an ABS light. Youll want to have the ABS codes checked and go from there.
Thank you so much it turned out to be both my relay and my alternator, thankfully got them both fixed and now were back on the road :)
Hi
Grand caravan 2005
Over Heating situation
1-)- I Replace the 2 Funs still problem
2-)- Replace the Radiator, & Thermostat, and still over Heating
3-)- Relace Water pump and still the problem
What can be the problem??
Thanks in advance
...please, please help me The Car Doctor with this relay I can't find on my 2008 Dodge Grand Caravan. I did a part all front of my car and nothing.
Also, I did replace the new timing chain and sprockets in the same car. The old chain was 1 inch loose when I install a new one it is very tide, so it spouse to be like that? Thanks for the very good info.......peter
Watch the video again.
OK. I have a ? Car Doctor. my 2000 Plymouth experienced the over heating in traffic yesterday. had the wifey and my 4 kids with me. it was 101° yesterday here in Sacramento. the temperature read normal or in the middle. van started to sputter and shake then died. once I got it started enough to get it on to a side street parked and out of the way. I noticed the fans not working. ive been in a processes of reteaching the system readiness so I can smog it. I was having an issue with an after market radio which I kept having to unhook the battery. which of course makes my stupid van forget its readiness. so stock radio is back in. I say all that. cause 3 days ago I was doing the steps for HOS2 readiness, cold soak over night, minimum 8hrs van sits, on keys in door. nothing to make the pcm wake up. so I do the run idle 5min to open loop operation, then of for 10min. while I was warming it up. the fans came on as soon as I heard the thermostat open(open loop), so that's normal operation, plus I did the A/C fan check then too, turning a/c on and both fans immediately came on, normal operation again. so when u found yesterday sitting on the side of the road. i turned key on but didn't start it then turned the a/c to low fans should have come on but didn't. I got the van cooled down poorer cold water all over the radiator rush hour traffic had thinned down and made it home. later I went to talk to the idiots at Autozone, and no I don't think they are all idiots but there are a few that no nothing about vehicles. I know a few managers so I when to talk to him. I had the engine light pop on when it died earlier yet he scans and finds no new codes nor any pending codes. he tells me to check but more likely replace my relay. I'm thinking OK. here's the weirdest part. I got get in the then van and call it inquiring minds, curiosity or Mikey engineering I started the van and turned on the a/c and low and behold the fans came on. I'm thinking WTF? and I leave it on as I drive home. 2 blocks from home I hit a big pot hole and the van of course bounced around but also the fans stopped working. and right then it started to sputter and pop again. but I made it home safe in my drive way. what could cause that to happen? I see in your clip here it was partially plugged into the relay. could this be my problem? its a head scratcher for sure. I'm a capable mechanic I've worked as one for over 15year, I've replaced the entire cooling system(rad,water pump,thermostat, all new hoses etc...), replaced tranny, just put new front calipers, rotors and pads. I got in a fender bender. no unibody,frame damage but needed new upper core support, hood and tranny cooler. so this has me just confused. any help is greatly appreciated. thank for this and so many other vids. you've saved my life more than once. so thanx again.
Anyone else notice the dead dragon fly on the radiator?
only one? I've had a hundred at a time on mine. So many dead grasshoppers you couldn't count. There's nothing so gross as cooking hopper guts on a rad!
I have a 2008 t&c change the fan and the plugs still no ground do u have any idea what it could be?
Relay?
my 1997 Plymouth Grand Voyager radiator cooling fans came on one morning about ten hours after I turned the key off. Is it the coolant temperature sensor, the relay or what? It's a 3.8L. I was told they didn't make that model that year with that engine. I bought the vehicle used.
Sounds like the relay is bad.
How do I test the relay?
Replace it and see if that fixes it.
