Air Door Actuator / Motor: Description and Operation
Blend Door Actuator - Description
DESCRIPTION
The blend door actuator (1) is a e reversible, 12 volt direct current (DC), servo motor. Models equipped with the MTC single zone heating-A/C system
have a single blend-air door, which is controlled by a single blend door actuator.
The blend door actuator for the single zone heating-A/C system is located on the driver side end of the HVAC air distribution housing, close to the dash
panel.
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.
