Circuit/System Description

WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

The rear compartment lamp is supplied voltage from the BCM via the inadvertent power courtesy lamp circuit. When the rear compartment lid is open, the rear compartment courtesy lamp switch is closed, providing a ground path for the rear compartment courtesy lamp and illuminating the lamp.
