K Yukon/Denali 4WD V8-5.7L VIN R (2000)
Vanity Lamp: Description and Operation
The Body Control Module (BCM) also provides power through CKT 40 (ORN) to the dome, reading, vanity mirrors, automatic day/night rearview
mirror with compass, and the power outside rearview mirror switch. The dome and reading lamps have a push button switch that must be activated in
order to light. CKT 150 (WHT) provides a ground path to ground G400 for circuit completion. CKT 156 (WHT) also supplies power when any of the
entry lights need illumination.
In order to light the vanity mirrors, the sunvisor needs to be pulled down, giving access to the mirror itself. Ground for the mirrors runs through CKT 150
(BLK) to ground G200.
The IP compartment box light works the same as the vanity mirrors.
