Air Door Actuator / Motor: Description and Operation
Mode Door Actuator - Description
DESCRIPTION
The mode door actuator (1) is a reversible, 12-volt direct current (DC), servo motor. The mode door actuator is located on the driver side end of the
HVAC air distribution housing, close to the instrument panel. The mode door actuator is mechanically connected to the floor, defrost/demist and the
panel-air doors.
The mode door actuator is interchangeable with the actuators for the blend-air door 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
connect 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.
