Rear Interior Power Liftgate Switch
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 rear interior power liftgate switch (located on the bottom of the liftgate trim panel) is a momentary contact switch that routes the voltage signal from the RGTM to ground when pressed. Pressing this switch closes the power liftgate. The power liftgate does not open or release the latch from the rear interior power liftgate switch.
