Actuator, RECIRCULATION Door: Operation

WARNING: This page is about a different variant/trim than selected.

The recirculation door actuator is connected to the A/C heater control or module (depending on heating and A/C system application) by a dedicated two-wire lead and connector of the Heating, Ventilation and Air Conditioning (HVAC) wire harness. The recirculation door actuator can move the recirculation air door in two directions. When the A/C heater control or module 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 or module reverses the voltage, the recirculation air door will move in the other direction. When the recirculation air door reaches its travel limit, the A/C heater control or module turns the voltage off.

When equipped with Automatic Temperature Control (ATC), the recirculation door actuator is diagnosed using a scan tool. Refer to DIAGNOSTIC CODE INDEX .

When equipped with Manual Temperature Control System (MTC). Refer to DIAGNOSIS AND TESTING .

The recirculation door actuator cannot be adjusted or repaired and must be replaced if inoperative or damaged.
