Actuator, RECIRCULATION Door: Description
The recirculation door actuator (1) for the Dual Zone heating and A/C system is a reversible, 12 volt Direct Current (DC) servo motor, which is directly connected to the pivot shaft of the recirculation-air door. The recirculation door actuator is located on the left side of the air inlet housing.
The recirculation door actuator is contained within a black molded plastic case with an integral wire connector receptacle (2). An output shaft with splines (3) connect it to recirculation door shaft and integral mounting tabs (4) allow the actuator to be secured to the air inlet housing.
The recirculation door actuator does not require mechanical indexing to the recirculation-air door, as it is electronically calibrated by the Heater, Ventilation and Air Conditioning (HVAC) Module. The heating and A/C system must be re-calibrated each time an actuator motor is replaced. Refer to STANDARD PROCEDURE .
The recirculation door actuator is interchangeable with the actuators for the blend and mode air doors.
