I'm get hot air from the driver side vent when the auto climate control is set at 60f. I have removed the actuator on the passager side and it is working fine. I have replaced it in the past to fix this problem. This time is different b/c when I move the blend door manually i still get hot air. I need help finding the part number if it is a bad blend door and any suggestions that you might have.

 

Here is my answer

 

Check rock auto or gm parts.com for part numbers then cross check Amazon for price comparison.
