You probably have a drivers side temperature door actuator that has failed. There should be a fault code stored in the A/C control module. If the problem turns out to be the actuator replacing the part is not to big of a job.
I am having the same problem on my 2003 Deville, where can i locate the a/c control module, and how do you retreive the code. also where is the temperature door actuator located. thanks
The left side actuator is located on the side of the HVAC module near the gas pedal. The right side actuator is located behind the glove box. Codes can be retrieved using a scan tool or the on board vehicle diagnostic system.
