Air Inlet Door Actuator
WARNING: This page is about a different car, the 2015 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.
The air inlet door actuator moves the air inlet door between the fresh and recirculated air positions on command from the HVAC control module. The air inlet mode door actuator is driven to, and automatically stops at, the full recirculated air or full fresh air inlet position and does not require a potentiometer circuit to monitor its position. The airflow mode door does not stop at any point between the recirculated air or fresh air inlet position.
