OPERATION

Non-switched power is supplied through Fuse 9 in the Underhood Accessory Fuse Block, and ground is provided by the Body Control Module. Regardless of the ignition switch position, the courtesy lamps illuminate when either door is opened if the courtesy lamp defeat switch is in the "-" position; or the courtesy lamp switch is pressed. The courtesy lamps will fade off approximately 8 seconds after the last door is closed. If a door remains unclosed, the lamps will remain on for approximately 5 minutes. At this time the Body Control Module will interrupt the ground path to conserve battery power.

When the courtesy lamp switch is pressed, the courtesy lamps are provided a direct path to ground and will remain illuminated until the switch is pressed again.
