Air Inlet Mode Door Actuator - Hybrid

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. 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 airflow mode door actuator contains a reversible electric motor and potentiometer. The potentiometer allows the HVAC module to monitor the position of the air inlet mode door. The potentiometer circuit consists of a 5-volt reference signal connected to one end of a variable resistor, and a signal ground connected to the other. A signal circuit is connected to a contact wiper, which is driven along the variable resistor by the actuator shaft. The signal to the HVAC module from the contact wiper indicates the position of the air inlet mode door. The HVAC module powers the actuator motor to move the air inlet mode door to the desired position. The HVAC module determines the desired air inlet mode door position based on the calculated outlet temperature.

The air inlet mode door actuator is located on the air inlet duct near the RH cowl side panel.
