The blend door actuator (1) for the heating and 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 interchangeable with the actuators for the mode-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 respective door linkage and three integral mounting tabs (4) that 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.
