COURTESY LAMP SWITCH/UNIT
DESCRIPTION
The courtesy lamps (1) provide overhead interior illu-
mination when the doors are opened and the courtesy
lamp defeat switch (3) is in the “—” position, or when
the courtesy lamp switch (2) is pressed. The courtesy
lamp defeat switch (3) can prevent the courtesy lamps
operation when the doors are opened if the “O” posi-
tion is selected. The courtesy lamp switch/unit cannot
be adjusted or repaired. If faulty, worn, or damaged,
the entire assembly must be replaced. For complete
courtesy lamp switch/unit removal procedures, refer to
Courtesy Lamp Switch/Unit removal in this section.
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.
REMOVAL
1. Disconnect the negative battery cable.
2. Using a trim stick (1), gently pry down and away
from the courtesy lamp switch/unit body (2) to
release the lens cover.
