Air Door Actuator / Motor: Description and Operation
Blend Door Actuator - Description
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.
