    Rear Climate Control Issue

    Hello All,

    I have been having issues with my 2005 Cadillac Escalade rear climate control. I could not get warm air to blow so first thing I checked and replaced was the rear blend door actuator. This didnt help and after re-calibrating i noticed it would turn to the full cold position after starting the truck, no matter what the setting. So, I replaced the rear control module (ACDelco 15-73506 Control Module Kit), re-calibrated and started the truck. I turned it to hot and it worked! I thought I solved my problem but no. I tried to turn it back cold but it wouldn't budge. I turned the car off and back on, and it went right back to full cold again. I tried re-calibrating multiple times to no avail. I have read and read and read about this subject and thought I had it nailed. What else could be causing this problem, bad air temperature sensor? Any input would be great please let me know if you have any questions.

    Replace the actutior as they can fail also when a over travel code is set which most likely what happened
