Air Door Actuator / Motor: Description and Operation
Servo Motor Control
Flap position, which directs the flow of air through the system, is controlled by servo motors; these may be driven in either a clockwise or anti-clockwise
direction by signals from the A/CCM. Motor, thus flap position, is monitored via a feedback potentiometer which is situated within the motor housing.
Servo motors control the following flaps:
RH and LH Air Intake (Fresh / Recirc)
Cool Air Bypass
