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 reading lamps are made up of the overhead console reading lamp, the dome/reading lamps (left and right) (DH6), and the lamps located in the rearview mirror (UE1). The overhead console reading lamp and the dome/reading lamps (left and right) lamps also function as courtesy lamps. Ignition voltage is supplied at all times to the reading lamp switch by the BCM via the inadvertent power courtesy lamp circuit. When the reading lamp switch is pressed, the switch is closed and voltage is supplied to the lamp, illuminating the reading lamp bulb. The reading lamp switch is part of the reading lamp assembly.
