The lift glass can be opened by operating the switch on the instrument panel or rotating the key cylinder in the endgate. Battery voltage is supplied to the lift glass actuators through the body control module (BCM). The BCM will pulse the LH and RH lift glass actuators when a release input is received through the key fob, endgate key switch, or the instrument panel switch.
