Great job, plus using the best tools, Snap-On, thanks for the instruction of the processes involved, though I don't plan to use BD USA this video is of great help! Thanks for posting!
Thank you! Thank you! You're videos are awesome and I've been waiting on this megacab with dual zone and rear vents rebuild video! I recently bought an 06 megacab Laramie and the air flow to the front portion of the cab is horrible. Definitely going to be doing this rebuild and cutting out of the rear vent netting. Thanks again!
Wow! Cannot say enough for you making this video. Just did my Mega this weekend with ne BD USA doors and it turned out perfectly thanks to your video. This is simply perfect. Thank you thank you thank you!!!!!!!!!!!!
Thank you for doing this video, I ordered my Blend Door USA kit for my mega cab yesterday and was wondering how it all would go together....Im not dumb but was somewhat worried....now I feel like with the instructions you have put out, I now have all the info on how to do the job! Now if I can find a video of yours that shows how to pull the dash on a 08 mega cab Laramie......the dash is different than the one you did on a manual transmission truck
Thank you for uploading this entire series regarding the Dodge Ram blend doors. I just received the blend door replacements from Blend Door USA and will likely be tackling this project next weekend. This is the only video I have come across showing the differences in the dual zone system which is a huge help to me as I have the dual zone system. Shout out to Blend Door USA as their customer service and quality doors are unmatched. Can I ask, what size weather stripping did you use on the exterior of the HVAC box? I'd like to have all the parts I need on hand once I start disassembly. Thanks!
I own a 2016 Ram 3500. The air stays relatively cold on drivers side, while hot on passengers side. The dealer checked the actuators and says they are ok, and the heater core is the problem, because it is probably clogged. He put some kind of liquid in the prestone, to unclog it… Personnaly, I thought that if the air was hot somewhere in the cabin, then the problem has to be with the actutors, because all the air has to go trough the heater core before the distribution of the air is done. What do you think?
im scratching my head wondering why there are only two screws in all the actuators. I'm in the middle of doing this exact install right now following your video. Is there a concern with me adding the third screw into the actuators? Thanks for the video, its a life saver.
Unbelievably Great! When can I bring my truck by?? Ha! The quality of these doors can be readily seen. Good work, Blend Doors USA! Anyone have a labor estimate for 12/2020? I'm located in northern Colorado. My low-mileage, clean 2006 Ram 3500 is an extended cab with dual-zone controls and about 18 months ago I suspected a blend door failed such that no heat is getting to the driver side, while the passenger side gets heat. The fail may also be intermittent, but I'm not totally sure. (Does anyone have a comment about my theory so far?). Is there a complimentary video for taking off the dash and removing the box?
Would it be possible to attach that bottom air vent onto a non-mega cab dual zone HVAC housing? I'm doing some stuff to my truck and was curious if it's possible to modify floor vents for the rear in my quad cab.
I put rear vents into my quad cab just like you're wanting to. You have to buy the lower half of the hvac box from a mega cab. There are internal differences that allow airflow. The top half is the same though.
@@flopster843 That's kind of what I thought. I've already invested in the dual zone hvac box, and I'm not even sure where I would find the bottom half of the shell. That would completely top off the conversion I'm doing. I'm swapping out my dash for one that has a Laramie wiring harness allowing me to have infinity sound, adjustable pedals, electronic 4x4(won't use that though) steering wheel controls, and one or two other things I'm forgetting I think. Sadly no bluetooth, but I can't seem to find that wiring harness anywhere, or more specifically any wreckers within Ontario, but I don't even know what to search for to find that at a wreckers.
Regarding the actuator motors, in the video you say they are all self indexing. So you are saying that once I'm finished with this complete kit I do not have to go to the dealer for any "position" calibration of any of the doors? (assuming all motors are fully functional" Thanks for the reply!
I just got done replacing my doors with a blend door usa kit. I had one broken door the mode one for panel was broken. Pur it all together still not getting defrost to work. It did not blow defrost before I pulled it apart. Any suggestions on what it could be I am thinking the actuator not working.
Look up under the dash while you cycle the controls and see if your actuator is turning. If it is bad, only use an oem mopar actuator. The aftermarket ones are junk.
Oh man this is great, exactly what i was looking for. I got a bad vibration in my blower fan, turns out the Recirc blend door has broken off. Go figure. No way I can pull the whole dash and replace it, should I just remove the door and leave it wide open? Or should I try to wedge it up in there to block one direction? Any ideas?
The dash is a lot easier to pull than you think. If you just want a temporary quick fix, pull the blower motor and pull the recirculation door out through the bottom. You might have to break the door to get it through though.
flopster843 Yup that’s what I went ahead and did. I live in an apt. Complex so anything where I’d have to pull out a bunch of parts is no bueno currently. Luckily I didn’t have to break anything to get it out, I’m planning on trying to replace the door without pulling the dash. Got a new door on order. Thanks man!
When mine broke. I took it out drilled a couple of holes in the door put it back in then zipped tied it to the inside cross bars so it only pulls outside air.
I have a question, 2007 dodge ram 3500 mega cab that has a problem that I haven't seen no one having my problem. Here is my ???? the heater controls fan speed works on all 4 settings but nothing else works, not a/c button, recycle door button, or the mirror defrost button. IT stays in the default mod( most defrost a little on floor) and not as hot as the truck. cool almost. Any thoughts or help would be appreciated
My guess is the control panel itself has failed. Check the electrical connector on the back of it to see if it has possibly come loose or has corroded pins.
My 2006 mega cab has been to the shop three times for the same problem $$$$. I am about to take this on myself. This is not as difficult as I thought. The problem is that the air flow varies tremendously and I can not control the a/c or heat temperature very well. Air flow is minimal at the dash, floor, and defroster. I can hear the fan pushing air but the air is not going out the vents. So far they have replaced the circulation door and the actuator. They also put in a control module for the temperature control on the dash and replaced the a/c compressor. I asked for all doors to be replaced and that did not happen. What would be your best guess as to what needs to be done? Thank you in advance.
The first thing I would check is to see if the evaporator is clogged with dirt. Remove the blower motor from the bottom and reach in the hole with a cell phone to take a picture of the evaporator. If it's dirty, flush it with water. Second thing is to check to see if all the doors are moving properly. You can see all the actuators and drivers with the box in the truck. Watch them while you cycle the controls and make sure they all move and stop like they should. If one spins more than 90 degrees, you have a broken door. Last thing is to cut out the mesh screen on top of the box. This is here to create a restriction in order to force more air out of the rear vents. Removing it will significantly increase front flow, but will also decrease rear flow.
minimal air flow--but blower is on high----its the Recirc door on far right. I bet its broken off laying on the blower motor---mine was !! You can fix it if you take out the glove box--break out the big plastic vent .
They do fail from time to time. Unfortunately, most of the replacements are of lesser quality than the OEM ones and fail quicker. I personally prefer to just run the originals until they die.
I'm having trouble with my unit. 06 mega dual. It had very limited air flow from the panel vents. I replaced all the doors and parts available and still have practically no air. Removing the glove box I can do a function test visually and the only door that doesn't seem to respond correctly is the panel door. I can see the actuator body itself move very slightly in both directions as if the panel door is stuck in position. Is there a cause for this. I really don't want to tear the dash back out of this truck
@@PP-xp2gm I had torn mine out and installed the aluminum aftermarket doors. Turns out that was my problem. The doors were timed correctly as per the video but had come loose enough to come out of time. Once they were retimed they seem fine. It was the temp control doors to be more specific. You will need to remove the dash and hvac box to make this repair
What would be the problem with having heat (hot air) coming out your vents but then have cool air coming out your defrost and floor with setting still on heat? Sometimes My air slowly takes time to change from vent to defrost or vice versa when I switch the air control knob? Any help would be appreciated!!!!!!
@@flopster843 It's usually hotter air on the passenger side and warmish cool air on the driver side vents when in full heat mode? The defrost though is just cool-warm air when in heat mode? The A/C blows out pretty cold air but does seem to take some time to change through the control cycle when I turned the knob from defrost, to vents, to floor? Sometimes it wont even change cycle until I start up my truck again or maybe the next day it'll change. It's like something is stuck to control where you want the air to go? Thanks for the response and I hope I answered your question right
@@brianjirish The actuators take a little time to cycle. If they're failing to do so consistently, check the electrical connector on the back of the control unit. They're known to work loose and sometimes burn pins. For the temp control, watch the blend door actuator while you cycle the temp. It should move about 90 degrees. If it cycles, pull the actuator off, disconnect the linkage rod, and move each one by hand. Try to feel if either one might be broke internally.
@@flopster843 I believe I have 5 total actuators. I could only get to 3 of them and all seem to be fine. I couldnt see the blend doors though unless I completely remove the dash. I will definitely look at the wiring behind control knob. I wont be able to do much until this weekend but I'll put out an update if i find and fix a problem so other ppl can learn from this. Thanks again for your input!!!!
@@brianjirish A single zone system has 4 actuators. Dual zone has 5. The two blend doors are in the center of the box tied together with a rod and driven by a single actuator. On a late third gen, they're accessible by pulling the glove box. Early third gen, you'll have to go up under the dash.
Lots of missed details in this video. There are 2 more bolts behind the radiator puke tank that hold the HVAC box to the firewall. You best remove those, or some shit is going to get broken as you yank on the box. All the obvious stuff is in the video, all the Gotcha stuff is not. The blend door USA kit i got required significant modification to get it to function properly. FYI
This video has nothing to do with removal from the truck, that's the other video. And most 3rd gen trucks do not have a coolant reservoir on the firewall, this one does not. What is this "significant modification" you speak of? If the doors didn't fit then you ordered the wrong kit or installed them backwards.
Mine damn sure does. So i don't know where you get your information. I just did the job in its entirity, watching these videos as i went. There are several differences, in each video, to my truck. So we must assume many other trucks out there are not like this video. It would be good to notate that these videos are not all inclusive, instead of pretending to be mr know it all god of the 3rd gen. You've missed a lot of little details. You cover the big steps but lack in the details, and we all know thats where the devil lives. Fortunately i found other peoples videos specifically about pulling the HVAC box and they notated the hidden fasteners. Ive got a bone stock 2006 mega, unique in no way.
Well there's your problem. This video is for a 2008 6.7L. The process is very similar, but not identical. All of my videos and the entire website are based off of this specific truck. Sorry if you were misled or misinformed about anything. However, those bolts were covered in the removal video. I just didn't have to remove the coolant overflow or the TCM to gain access because this truck does not require them. Either way, glad you got it all figured out.
Just spreading the word that some trucks are different from the videos before someone makes a big oops. These box halves are not available anywhere but the junkyard, and are real brittle from the Arizona heat. Be careful out there, you don't want to make an expensive mistake.
ive checked all connections all acuators are functioning...any idea why I am getting less airflow on passenger side vents, I assumed there was one channel of flow that split two ways but is there actually a blend door for driver and passenger if only one climate control? Im stumped
Yes. The entire box is split into seperate chambers and controlled together. If all the actuators are functioning properly, then something has to be blocking your evaporator causing a reduction in airflow.
flopster843 Could a blockage at evap cause less airflow to just the passenger side ? Also, if a blend actuator is not functioning right will it cause less to one side...my impression the blend door either works correctly or not . Cheers thank you
On the blend door actuators which one is the driver (left) according to snap on computer . I'm getting full heat in driver vents and cold in passenger and it seems all my doors are fine but the actuator for the driver zone says its bad I'm trying to figure out which is which so I can replace thank you!
I am not familiar with the snap-on system and how it reads actuators. You can look behind the dash and see the actuators, can you tell which one isn't moving?
Would it be difficult to convert the dual zone to a single zone? Is it as easy as just buying their single zone kit which would save $100? My truck is mainly a weekend work truck so I have never used this feature.
Yes, it is that easy. Buy the single zone kit and unbolt the extra actuator from the back of the box. You'll control the entire system with only one of your sliders
When I install the new single zone door what will hold the far side in place? I'm referring to the far side where I'm leaving the back actuator off. Would I reuse the cam driver without motor?
The single zone doors have a bolted on cap to fill the gap in the box where the rear cam would go. The plastic housings are the same and the oem doors use a plastic plug to do the same thing.
Thank you so much for your videos and help with this! I was originally going to cut in the dash and do the “Heater Treater” way but your step by step videos make this look simple and I’m now going to pull dash and do it the right way.
@@flopster843 I am getting ready to purchase a kit from Blend Door USA, is it possible to convert my SLT single climate system over to the dual climate system?? I assume i would just need to buy the dual climate kit, and buy an additional actuator? Any information is greatly appreciated!
Help! 04 Ram. Dual zone. I have repaired the ReCirc door. My problem is this--the defrost works and is hot...but when i switch to floor or middle vents = No heat !! just cool air ..also the air still "leaks out" the defrost vents. If i can get heat out of ALL vents im good---SO which door would cause no heat except defrost vents ??

wild guess, is the top back actuator controls the passenger side temp?, if unplugged and get a single piece blend doors, I can make it single zone?
Odds are you need to pull the dash every 10 years to replace the evap core so why spend 500 on aluminum doors
Can you pull the dash off. Leave box attached to truck. Pull box apart to change doors.
You can only get to the recirculation door and the panel door that way. All others require the box to be split, and the screws are all on the bottom.

It would be good to notate that these videos are not all inclusive, instead of pretending to be mr know it all god of the 3rd gen. You've missed a lot of little details. You cover the big steps but lack in the details, and we all know thats where the devil lives. Fortunately i found other peoples videos specifically about pulling the HVAC box and they notated the hidden fasteners. Ive got a bone stock 2006 mega, unique in no way.
p.s. its not my job to further your brand, so do your own homework. i did.
Well there's your problem. This video is for a 2008 6.7L. The process is very similar, but not identical. All of my videos and the entire website are based off of this specific truck. Sorry if you were misled or misinformed about anything. However, those bolts were covered in the removal video. I just didn't have to remove the coolant overflow or the TCM to gain access because this truck does not require them. Either way, glad you got it all figured out.
Just spreading the word that some trucks are different from the videos before someone makes a big oops. These box halves are not available anywhere but the junkyard, and are real brittle from the Arizona heat. Be careful out there, you don't want to make an expensive mistake.
ive checked all connections all acuators are functioning...any idea why I am getting less airflow on passenger side vents, I assumed there was one channel of flow that split two ways but is there actually a blend door for driver and passenger if only one climate control? Im stumped
Yes. The entire box is split into seperate chambers and controlled together. If all the actuators are functioning properly, then something has to be blocking your evaporator causing a reduction in airflow.
flopster843 Could a blockage at evap cause less airflow to just the passenger side ? Also, if a blend actuator is not functioning right will it cause less to one side...my impression the blend door either works correctly or not . Cheers thank you
flopster843 Sorry forgot to ask if a heater core that is plugging up on one side would also cause less airflow...or would it only affect heat temp
On the blend door actuators which one is the driver (left) according to snap on computer . I'm getting full heat in driver vents and cold in passenger and it seems all my doors are fine but the actuator for the driver zone says its bad I'm trying to figure out which is which so I can replace thank you!
I am not familiar with the snap-on system and how it reads actuators. You can look behind the dash and see the actuators, can you tell which one isn't moving?
It's hard to tell but I can tell you it's similar to the box in the video except I don't have back seat vents
All it said was driver blend door actuator which I'm thinking is the one that has the link to operate both blend doors in unison
If it's the one that controls both sides in a single zone system, then it's the one in the center-top with the linkage rod connected to it.
It's a dual zone system no rear vents
Would it be difficult to convert the dual zone to a single zone? Is it as easy as just buying their single zone kit which would save $100? My truck is mainly a weekend work truck so I have never used this feature.
Yes, it is that easy. Buy the single zone kit and unbolt the extra actuator from the back of the box. You'll control the entire system with only one of your sliders
When I install the new single zone door what will hold the far side in place? I'm referring to the far side where I'm leaving the back actuator off. Would I reuse the cam driver without motor?
The single zone doors have a bolted on cap to fill the gap in the box where the rear cam would go. The plastic housings are the same and the oem doors use a plastic plug to do the same thing.
Thank you so much for your videos and help with this! I was originally going to cut in the dash and do the “Heater Treater” way but your step by step videos make this look simple and I’m now going to pull dash and do it the right way.
@@flopster843 I am getting ready to purchase a kit from Blend Door USA, is it possible to convert my SLT single climate system over to the dual climate system?? I assume i would just need to buy the dual climate kit, and buy an additional actuator? Any information is greatly appreciated!
Can you please send me the part number for the complete assy
COULD YOU DO A RAM 3500 2010 MODEL
I'm planning on doing a 4th Gen Ram this winter if I'm able to get one.
Can you fix mine
all
Help! 04 Ram. Dual zone. I have repaired the ReCirc door. My problem is this--the defrost works and is hot...but when i switch to floor or middle vents = No heat !! just cool air ..also the air still "leaks out" the defrost vents. If i can get heat out of ALL vents im good---SO which door would cause no heat except defrost vents ??
