Air Door Actuator / Motor: Description and Operation
Recirculation Door Actuator - Operation
OPERATION
The recirculation door actuator is connected to the A/C-heater control through the vehicle electrical system by a dedicated two-wire lead and connector
of the instrument panel wire harness. The recirculation door actuator can move the recirculation-air door in two directions. When the A/C-heater control
pulls the voltage on one side of the motor connection high and the other connection low, the recirculation-air door will move in one direction. When the
A/C-heater control reverses the polarity of the voltage to the motor, the recirculation-air door moves in the opposite direction. Once the A/C-heater
control makes the voltage to both connections high or both connections low, the recirculation-air door stops and will not move.
The recirculation door actuator cannot be adjusted or repaired and it must be replaced if inoperative or damaged.
