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 top of the HVAC housing.

The blend door actuator is contained within a black molded plastic housing with an integral wire connector receptacle (2) and three integral mounting tabs (3) that allow the actuator to be secured to the HVAC housing. The blend door actuator also has an output shaft with splines that connects it to the linkage that drives the blend-air door. The blend door actuator requires mechanical indexing to the blend door linkage.
