GENERAL INFORMATION
Each vehicle is equipped with various lamp assem-
blies. A good ground is necessary for proper lighting
operation. Grounding is provided by the lamp socket
when it comes in contact with the metal body, or
through a separate ground wire.
When changing lamp bulbs check the socket for
corrosion. If corrosion is present, clean it with a wire
brush and coat the inside of the socket lightly with
Mopar Multi-Purpose Grease or equivalent.
connections, charging system, headlamp bulbs, wire
connectors, relay, high beam dimmer switch and
headlamp switch. Refer to Group 8W, Wiring Dia-
grams for component locations and circuit informa-
tion.
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. Refer to
Group 8W, Wiring Diagrams.

PROCEDURES—XJ
The multi-function switch contains electrical cir-
cuitry for:
•
Headlamp Dimmer Switch.
•
Passing Lights.
•
Turn Signals.
•
Hazard Warning.
•
Windshield Wiper.
•
Pulse Wiper.
•

This integrated switch is mounted to the left hand
side of the steering column. Should any function of
the switch fail, the entire switch must be replaced.
The multi-function switch also serves as a fog lamp
lock-out circuit. The circuit to the fog lamp switch is
completed only when the dimmer switch is in the low
beam position.
