DESCRIPTION AND OPERATION
DIAGNOSTIC PROCEDURES
DESCRIPTION
JX vehicles use lighting on the interior and exte-
rior of the vehicle for illuminating and indicating
purposes. Lighting circuits are protected by fuses or
circuit breakers. Lighting circuits require an overload
protected power source, on/off device, lamps and body
ground to operate properly. Plastic lamps require a
wire in the harness to supply body ground to the
lamp socket. Lamp sockets that are exposed to mois-
ture should be coated with Mopar
t Multi-purpose
Grease, or equivalent, to avoid corrosion. If a socket
has become corroded, clean socket and bulb base with
abrasive fiber sanding pad or metallic bristle brush.
Replace sockets and bulbs that are deformed from
corrosion that could prevent continuous body ground.
Wire connectors can make intermittent contact or
become corroded. Before coupling wire connectors,
inspect the terminals inside the connector. Male termi-
nals should not be bent or disengaged from the insu-
lator. Female terminals should not be sprung open or
disengaged from the insulator. Bent and sprung termi-
nals can be repaired using needle nose pliers and pick
tool. Corroded terminals appear chalky or green. Cor-
roded terminals should be replaced to avoid recur-
rence of the problem symptoms. Wire connector
terminals should be coated with Mopar
t Multi-pur-
pose Grease, or equivalent, to avoid corrosion.
Begin electrical system failure diagnosis by testing
related fuses and circuit breakers in the fuse block
and engine compartment. Verify that bulbs are in
good condition and test continuity of the circuit
ground. Refer to Group 8W, Wiring Diagrams, for
component location and circuit information.
SAFETY PRECAUTIONS
DESCRIPTION
WARNING: EYE PROTECTION SHOULD BE USED
WHEN SERVICING GLASS COMPONENTS. PER-
SONAL INJURY CAN RESULT.
CAUTION: Do not touch the glass of halogen bulbs
with fingers or other possibly oily surface, reduced
bulb life will result. Do not use bulbs with higher
candle power than indicated in the Bulb Application
table at the end of this group. Damage to lamp can
result. Do not use fuses, circuit breakers or relays
having greater amperage value than indicated on
the fuse panel or in the Owners Manual.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges are not holding the com-
ponent in place.
