Temperature Blend Door Actuator
WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
The temperature blend door actuator moves the temperature blend door on command from the temperature control switch using a reversible electric motor. The temperature blend door actuator contains an internal controller that will recognize the temperature control switch signal and drive the temperature blend door to the desired position.
The temperature blend door actuator is located on the heater core and evaporator core housing near the glove compartment.
