Door Actuator - Air Inlet
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
The air inlet mode door is a stepper motor style actuator. The FCIM monitors the air inlet mode door position by counting the motor steps as it rotates. The FCIM drives the actuator motor in the direction necessary to move the air inlet mode door to the position set by the recirculation button and the in-vehicle temperature and humidity sensor information.
