Reading through the forum, it definitely seems like its' the air mixture control motor that is gone.

I have read MADSLEG's fix, but it seem like it is for the recirculating air motor and not the Air mixture motor

Although farther down, he says they are the same motor.

Could someone please tell if if MADSLEG's fix above is the right motor that I should be looking at?

This post says MADSLEG's repair is for the air re-circulating flap and not the air-mixture flap.

Please help alleviate my confusion!!
Practically every new member does not fully complete the registration form by including the year and model of their vehicle. Please click on USER CP to the left, then click on EDIT PROFILE, scroll down to ADDITIONAL INFORMATION and insert the year and model of your truck.

In Madsleg's photos the arrow pointing to #2 is the Blend Air Motor (Air Mix Motor). The Fresh Air Circ. motor is not even in the photo since it is all the way to the right of the dash.

All the actuator motors in the A/C-Heater system are not all the same. Everyone has its' own part number and is VIN specific. So if you are going to do the job yourself, get the motor from the dealer, who will supply you with the correct one.
