Air Door Actuator / Motor: Description and Operation
Mode Door Actuator - Description
Front
DESCRIPTION
This vehicle uses two mode door actuators (1) which are reversible, 12-volt direct current (DC), servo motors. The mode door actuator for the
panel/defrost/demist/floor air doors is located on the driver side end of the HVAC air distribution housing. The mode door actuator for the 2nd row air
door is located on the rear of the air distribution housing near the front of the floor console area. The mode door actuators are mechanically connected to
the mode-air doors.
The mode door actuator is interchangeable with the actuators for the blend-air door(s) and the recirculation-air door. Each actuator is contained within an
identical black molded plastic housing with an integral wire connector receptacle (2). Each actuator also has an identical output shaft with splines (3) that
connects it to its door linkage and three integral mounting tabs (4) that allow the actuator to be secured to the HVAC housing. The mode door actuator
does not require mechanical indexing to the mode-air doors, as it is electronically calibrated by the A/C-heater control.
Rear
DESCRIPTION
The rear mode door actuator (1) is a reversible, 12-volt direct current (DC), servo motor. The rear mode door actuator is located on the back of the rear
HVAC housing. The rear mode door actuator is interchangeable with the actuator for the rear blend-air door. Each actuator is contained within an
identical molded plastic housing with an integral wire connector receptacle (2). Three integral mounting tabs (4) allow the actuator to be secured to the
