INTERIOR COURTESY AND LUGGAGE COMPARTMENT

LAMPS

Interior Courtesy Lamp Inoperative

CAUTION : Always make sure there is an electrical
load (lamp bulb, etc.) in any circuit between battery
terminals. Do not make a short circuit between bat-
tery terminals with a jumper wire. Hazardous spark-
ing would result.

Test Description
The number(s) below refer to step(s) on the diagnostic

table.

1. Bulb test. Clip one end of a jumper wire to the neg-

ative battery terminal. Clip the other end of the
jumper wire to the end of the bulb. Take the free
end of the bulb (the end without the jumper at-
tached) and touch it to the positive battery terminal.

Step

Action

Value(s)

Yes

1. Remove the interior courtesy lamp bulb and
