Cold air coming from driver's side when heat is on. Passenger side is OK.

The heat in that vehicle is controlled by a blend door on each side that regulates heated air flow. It is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.
