Liftgate Window Latch Release
WARNING: This page is about a different car, the 2023 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
The BCM sends a voltage signal to the liftgate window glass release switch. When the liftgate window glass release switch is pressed, the voltage signal is routed to ground, indicating a request to release the liftgate window latch. The BCM momentarily provides voltage to the liftgate window latch to actuate the release motor.
The BCM releases the liftgate window latch only after electronically unlocking the doors first.
