ACTUATOR, Recirculation Door: Description: Description
The heating-A/C system uses a reversible, 12-volt direct current (DC) servo motor which mechanically positions the recirculation-air door. The recirculation door actuator (1) is located on the side of the HVAC air inlet housing.
The recirculation door actuator is interchangeable with the actuators for the blend-air door and the mode-air door. Each actuator is contained within a black molded plastic housing with an integral wire connector receptacle (2) and integral mounting tabs (3) that allow the actuator to be secured to the HVAC housing. The recirculation door actuator output shaft (4) is directly connected to the pivot shaft lever of the recirculation-air door. The recirculation door actuator does not require mechanical indexing to the recirculation-air door, as it is electronically calibrated by the A/C-heater control.
