Air Door Actuator / Motor: Description and Operation
Mode Door Actuator - Description
DESCRIPTION
The mode door actuator (1) for the heating-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 right side of the HVAC air distribution housing.
The mode door actuator is contained within a black molded plastic housing 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-air doors, as it is electronically calibrated by the A/C-heater control.
The A/C-heater control must be recalibrated each time an actuator motor is replaced . See: Testing and Inspection/Component Tests and General
Diagnostics/HVAC System Test
The mode door actuator is interchangeable with the actuators for the recirculation and blend-air doors.
