On climate control systems without automatic temperature controls, the blower motor speeds are controlled by a switch wired to a stepped resistor that usually includes a thermal fuse.

What are the symptoms of a bad AC actuator?

Air coming out from the wrong vents, clicking noises coming from behind the dashboard or not being able to control the temperature or re-circulated or fresh air mode in your car is a sign of a bad air door actuator motor. Exhaust fumes inside the cabin. What are the symptoms of a bad temperature blend door actuator?
