I recently lost all control on the passenger side climate control. Now it randomly switches from heat to cold on its own. What do I check first? 1997 Buick Park Ave Ultra.

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.

Fair enough, but what do I check first to determine all this?
