Savana 3/4 Ton Van V8-5.3L VIN T (2003)
Vanity Lamp: Description and Operation
VANITY LAMPS
The inadvertent supply voltage circuit of the BCM provides battery positive voltage to each vanity mirror lamp. When the vanity mirror cover on the
sunshade is opened, a switch closes to provide a ground circuit and the vanity lamp illuminates. Ground is provided to the vanity lamps at G347.
Voltage for the inadvertent supply voltage circuit is from the TBC 4 fuse 11 in the underhood fuse block directly through the BCM to this circuit.
