Circuit Description
WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
Battery positive voltage is supplied to the right rear power window switch and the up and down relays through the window lockout signal circuit. If the window lockout function is disabled, the BCM supplies battery positive voltage to the switch and relays and the right window operates normally. If the window lockout function is enabled, the BCM will not supply battery positive voltage to the switch and relays and the right rear window will be inoperative unless it is operated from the driver power window switch.
