Have dual controls. Everything working fine; then all of a sudden my driver's side will blow out like temp control is on 'hot'. I can turn off engine and it will correct and blow cold air. will malfunction again in one hour, one day, or one week.
A/C Blows hot air on driver, but not on passenger on 2005 Chevrolet Silverado 1500
Most likely the temperature door actuator for the drivers side is failing and will require replacement. Fault codes stored in the a/c control module should confirm it this is the case.
YES, Replaced this ($700) and works fine. The door was cheeeeep but the labor was extensive as they had to take apart the whole dash to get to it.
I have the same problem in my 06. I replaced the air door actuator located under the glove compartment on the passenger side... No luck. Apparently there are 2 of these, with the second one located behind the radio, deep in the dash. Do you happen to know what the part number is? or where you found it? I can only seem to find the one I already replaced.
