I have a 2005 buick terraza. This has happened twice over a month. Both heat controls are on hot. The drivers side is cold and the passenger is hot. How do I fix?

The temperature is controlled by the use of an air mix door that is operated by an electric motor/actuator. This door can be jammed or the actuator can be inoperative or have stripped plastic gears internally.
