Blend door motor won't stop going
I was told that the plastic coupling that connects the blend door and the motor may be broken, since I have no regulation of my hot and cold. Followed the direction to take it off, and sure enough the little plastic coupling is broken. Bought a new one at the dealer for the out rageous price of $15.00. Now for the weird part. I try and install it, and in trying to align it up, I started my truck, had the temp dial set to full hot. The motor keeps turning and turning. Mine has three electrical connection points in the plug. Was told, when the motor sences the "spike" as the door is fully in one direction, the motor is suppose to stop. I tried stopping it with my fingers and even a pair of pliers. It's still runs. I think this is what broke the plastic couplingin the first place. I don't really want to install it and see it happen again, and have to spend another $15.00 on a new one. What else could be wrong, in why the motor won't stop?

Could be electrical.. It will cost about 75-100 but I would bring it to the dealership and have them run a diagnostics test.. What year is your truck?

Or you could call the dealership and explain what's going on.. They are usually pretty good at helping over the phone

mroe1, you could help us to help you, if you would please fill out the USER CP up at the top of the page.
We just need the pertinent information like the vehicle information
Year, Model, Engine

If your vehicle is a dodge ram, between 2002 - 08 , you can watch these 3 videos, it pretty well covers the heating & a/c system in those years Rams

I would venture a guess that the actuator itself is bad but it could also be a wiring problem.

Well I took the chance and put the plastic coulpler in, re-installed the motor and started the Truck, It seems to work fine. I guess it does sence the door stopping and stops the motor. At least it hasn't broke the new coulpling. Thanks to all for teh advise
