The blend 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 blend-air door. The blend door actuator is located on the left side of the HVAC air distribution housing.
The blend door actuator is contained within a black molded plastic housing with an integral wire connector receptacle (2). An output shaft (3) with splines connect it to the blend door linkage and integral mounting tabs (4) allow the actuator to be secured to the HVAC housing. The blend door actuator does not require mechanical indexing to the blend-air door, 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. Refer to STANDARD PROCEDURE .
The blend door actuator is interchangeable with the actuator for the mode-air doors and the recirculation-air door.
