Air Inlet Mode Door Position
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The air inlet mode door actuator moves the air inlet door between the fresh and RECIRC positions on command from the HVAC module. The air inlet mode door actuator is driven to, and automatically stops at, the full RECIRC or full fresh air inlet position and does not require a potentiometer circuit to monitor its position.
