Actuator, Mode Door: Description
The mode door actuator (1) for the Dual Zone heating and A/C system is a reversible, 12 volt Direct Current (DC) servo motor, which is mechanically connected to the mode-air doors. The mode door actuator is located on the driver side end of the air distribution housing.
The mode 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 mode door linkage and integral mounting tabs (4) allow the actuator to be secured to the air distribution housing.
The mode door actuator does not require mechanical indexing to the mode door linkage, 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 mode door actuator is interchangeable with the actuators for the recirculation and blend-air doors.
