Rear Power Liftgate Control Switch
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The rear power liftgate control switch (located on the left rear quarter trim panel) is a momentary contact switch that routes the voltage signal to ground from the LTM when pressed. Pressing this switch closes the power liftgate (if set to enabled in the message center). The power liftgate does not open or release the latch from the rear power liftgate control switch.
