Yes, it is the heatertreater

Dodge Ram, blend door auto AC heat replacement part

I have not actually gotten around to doing the install yet, but I bought all the doors

I will be tackling this in the spring. Does anybody make any better than stock parts to replace these often failing stock parts?

Thanks. I had already watched the video, and the parts looked he same (hence my question). I also was a little concerned, since the heat treater videos were about cutting out and installing the new doors. I am not interested in cutting, I was more looking just to replace.

I think I may have just suffered the dreaded recirc door problem on my `03 during my last road trip. My AC, heater and defrost all work great, but no matter where I set the knob--floor, dash, defrost, fresh or recirculated air it only blows out the front dash vents. There was about a two week period where I noticed the problem, but if I adjusted the knob it would eventually switch to the correct function. I also noticed several small bits of foam that came up through the defrost vents and settled on the top of the dash. The puzzling thing is that I haven't noticed the telltale sounds of the door hitting the fan or other sounds people have reported. Am I correct in concluding that A) this is a recirc door problem, and B) it is the door behind the glove box and therefore an easy repair?



Thanks.

that sounds like a blend door problem. Remember blend door is what the air is coming out of, recirc door is just either outside air or recirculating inside air.

See post #22 above. I was in the same boat. I wasn't about to cut into anything, so I pulled the entire dash to do the replacement the correct way.



But at the end of the day, you're either cutting into the box, or you're pulling the dash.

This looks great. Can you tell me where I get the new door and pivot and the part number please. 06 Megacab. Same problem.

Thanks, Mike on FL.

Are you looking for OEM Mopar replacements or steel door and pin from Heatertreater? If HT, see post #23. If Mopar, any dealer can set you up.

Thanks. I clicked the HT link in this post (Dodge Ram, blend door auto AC heat replacement part) and based on the symptoms I am experiencing--I still get full temperature control, it appears to be "Mode Door 1" that has failed, but I'm not sure if it is the door, limit pin or the actuator that is broken:

Mode Door 1.



a. This door regulates air flow to either the dash vents or defrost/floor. If you have air flowing only through the vents with no defrost or floor, this door is failing. From our experience, this door is usually the first domino to fail. Not sure why, just is.​

Either way, it's obviously not the easy door to replace and sometime this summer or fall I'm going to be pulling part of the dash to fix it. On the bright side, the air is coming out of the vents I need for the next several months. If it was winter I would need both the defrost and the floor vents. In the summer I only use the dash vents so that nice air conditioned air is blasting out on me.

My mode door just went this week. Love this site because I've never heard of heatertreater before, so I'll be replacing my doors with their upgrade parts.

Mopartech,



Looks like you are using the 68004226ac kit, but only removing the broken door and servo from the truck and ONLY installing the new door and servo motor from the kit and completing the R&R, correct?



What are the 2 extra black plastic pivots from the kit for?



Thanks,



Gary

I answered my own question by installing it. The damper plate, new servo and pin were the only parts I installed. It's working. I saw where they added stops in the housing on the new one too.



My truck is an '05 and you have to take off a lot of plastic panels to get to the same spot as the '06 pictured.

Good thing you answered your own question -

as you're asking on a thread with a last post of over a *year* ago. .

Yup, seen it happen before also sent OP a PM.



I bet this ain't the last time this problem will need attantion too for someone elses truck.

 

[FFL8N]

I want to bring this back up to the top... . My truck is now blowing most of the air out the floor vents. The back of the truck and the floor vents get about 80 percent of the air when the control is set to the dash vents. Is this a control problem or will one of the blend doors cause this??

Well after the second door broke after replacing the first one about 2 years ago, I ordered a heater treater to reslove the recirc door issue. But as a temp fix for now. I went to Home Depot, bought a 2" x 1/2" ID long galvanized pipe nipple, and some JB WELD Plastic 2 part epoxy @ Napa auto parts. Took out the bench grinder, ground down the outer diameter to fit the pocket hinge in the duct near the electric actuator, then cut a slot, length-wise on the nipple, then cut it to legth, approx 1. 25" slide over the broken hinge pin and add strength. It takes a little trial and error, but the nipple did slid over the broken pin and the slot resides on the panel pin. I filled it with J WELD, waited about 5 minutes for cure and inserted back into the box. so far it works great, until something else gives way... . A Metal sleeve over a plastic hinge, how much more hill billy can ya get?

 

[DavidHook]

If you turn your blower fan on high and your dash shakes wildly, more than likely the broken hinge pin migrated to the squirrel cage causing an unbalanced condition, first sign you door is inop.
