RECIRCULATION Door Actuator: Operation

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

The recirculation door actuator is connected to the body control module (BCM) through the vehicle electrical system by a dedicated two-wire lead and connector of the HVAC wire harness. The recirculation door actuator can move the recirculation door in two directions. When the BCM 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 BCM reverses the polarity of the voltage to the motor, the recirculation air door moves in the opposite direction. When the BCM makes the voltage to both connections high or both connections low, the recirculation air door stops and will not move. The BCM operates the recirculation door actuator on a timed actuation period.

The recirculation door actuator can be diagnosed using a DRBIII® scan tool. Refer to BODY DIAGNOSTIC PROCEDURES - EXCEPT COUPE article for more information.

The recirculation door actuator cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
