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 vanity mirror lamps are supplied voltage from the BCM via the inadvertent power courtesy lamp circuit. When the mirror cover is open, the mirror cover switch is closed, providing a ground path for the vanity mirror lamps and illuminating the lamp.
