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.

Question: A/C Blows hot air on driver, but not on passenger

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.
