Access Panel Description and Operation for GMC Truck Savana - AWD 2003

The access panels can be opened by operating the corresponding button on the key fob. Battery voltage is supplied to the access panel relays through the rear fuse block. The BCM will pulse the access panel relays when a release input is received through the key fob. The access panel actuators will then operate, allowing the panel to open.
