Mode Door Actuator
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, and 2002 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
The mode door actuator is an electric motor. It mechanically positions the panel/bi-level door and the floor/defrost door. This actuator contains a potentiometer which allows the BCM (for both manual and ATC systems) to know the exact position of the mode doors at all times. The mode door actuator is not serviceable and must be replaced if found to be defective.
