Door Latches
WARNING: This page is about a different car, the 2018 Ford Edge. 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 lock actuator, lock/unlock feedback switch, and the door ajar switch. The door lock actuators operate in 2 directions, depending on the polarity of the voltage. The door latches can be lubricated, if needed.
