LAMP DIAGNOSIS
GENERAL INFORMATION
LH vehicles use lighting on the interior and exterior
of the vehicle for illuminating and indicating pur-
poses. Lighting circuits are protected by fuses or cir-
cuit 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, 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, in-
spect 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 ter-
minals can be repaired using needle nose pliers and
pick tool. Corroded terminals appear chalky or green.
Corroded terminals should be replaced to avoid recur-
rence of the problem symptoms. Wire connector termi-
nals should be coated with Mopar, Multi-purpose
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 com-
ponent location and circuit information.
SAFETY PRECAUTIONS
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.
HEADLAMP DIAGNOSIS
LH vehicles built for use in Canada are equipped
with a Daytime Running Lamp (DRL) system. The
DRL system operates the headlamps at 50% illumina-
tion with the headlamp switch OFF and the engine
running. The DRL system is controlled by the Day-
time Running Lamp Module located on radiator clo-
sure panel on the right side of the engine compart-
ment. The DRL module overrides the headlamp
switch when the headlamps are turned OFF. The
headlamps operate normally when the headlamps are
turned ON.
When a vehicle experiences problems with the
headlamp system, verify the condition of the battery
connections, charging system, headlamp bulbs, wire
