Newbee with heater vent/switch control issue

[damien256]

Hi all; I was wondering if anyone else has an issue with heater controls. The problem is when I turn dash mounted switch to vent only to the foot area, it continues to send most of the heat/ac through the defrost vents. I get plenty of heat and a/c, the system is not directing it where the switch tells it too. I do not know where to start. Are there any TDR veterans with ideas where to look or how to diagnose?



Thanks

This is a known issue with the he Dodge pick-up trucks. The issue is the actuator arm on the blend door fails over time. I believe a couple of issues back in the TDR quarterly magazine was an article publlish on how to take the dash apart and fix the blend door failure. I believe that this was done by Joe Donnelly a TDR writer and member of this forum.

Welcome to the TDR!

Agree with jim,, there are a few problems with the blending door arm. Welcome to the TDR. The TDR is in Pahrump Nevada right now doing a Rally. If you are near here, come over tomorrow to a show-n-shine and find some people to talk to. We alway meet here on the first week in may.

Thanks for your help guys. I found the article, with detail pics and directions. TDR is an awesome forum. Lots of great tech articles and fun stuff. I look forward to being a long term member.
Thanks again guys.

The dealer just quoted me $469 to do the blend door fix. My questions are: Is that price reasonable? and is the fix going to last or is it going to fail like the original did?

I thought that the whole dash needed to come apart and the dealer said this new fix does not require near the labor that the old remedy required. Anyone with experience with this new fix?

I'd be curious as to how the new fix that doesn't require the dash to be removed would work. I had more than one issue in my HVAC unit. It required the dash to come out just to get the whole unit out. The stop broke off the actuator side of the blend door which in turn caused the blend door to keep going til it was completed broken. The recirc door had the exact same thing. It took me about 8 hours labor to do the repair. I thought I had the right doors since I ordered them before I did the repair. Didn't have the right blend door. In many situations the stop on the lower housing would break instead of the actuator stop. That would require the whole housing being replaced. The research that i did here paid off with step by step instructions with pictures on the entire project. Parts numbers were very helpful as the dealer didn't have a listing on the blend door other than the entire bottom housing. I don't have any faith in the repair lasting any longer than the original. The same parts went back in as broke originally. Good luck and if you learn what the easier fix would be please let us know.

If it is just the recirc door a good tech can do it in about an hour and a half. They just pull the dash back and snap the new housing in.
