Scheme 8: DESCRIPTION

The heating-A/C system uses a reversible, 12-volt direct current (DC) servo motor which mechanically positions the blend-air door. The blend door actuator (1) is located on the driver side of the HVAC housing.

The blend door actuator is interchangeable with the actuators for the mode-air doors and the recirculation-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 blend door actuator output shaft (4) is connected to the linkage that drives the blend-air door. 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.
