Door Latches
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The door latches are sealed units and contain the door latch lock/unlock switch, lock actuator, and ajar switch. The door lock actuators operate in two directions, depending on the polarity of the voltage. The door latches can be lubricated, if needed.
