LAMP DIAGNOSIS
GENERAL INFORMATION
LH 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 over-
load protected power source, on/off device, lamps and
body ground to operate properly. Plastic lamps re-
quire a wire in the harness to supply body ground to
the lamp socket. Lamp sockets that are exposed to
moisture 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
insulator. Female terminals should not be sprung
open or disengaged from the insulator. Bent and
sprung terminals can be repaired using needle nose
pliers and pick tool. Corroded terminals appear
chalky or green. Corroded terminals should be re-
placed to avoid recurrence of the problem symptoms.
Wire connector terminals should be coated with Mo-
par, Multi-purpose Grease or equivalent to avoid cor-
rosion.
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
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 service
another, it should not be necessary to apply excessive
force or bend a component to remove it. Before damag-
ing a trim component, verify hidden fasteners or cap-
tured edges are not holding the component 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 Daytime
Running Lamp Module located on radiator closure
panel on the right side of the engine compartment. 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 head-
lamp system, verify the condition of the battery con-
nections, charging system, headlamp bulbs, wire con-
nectors, relay, high beam dimmer switch and headlamp
switch. Refer to Group 8W, Wiring Diagrams for com-
ponent locations and circuit information.
SYMPTOM
Headlamps are dim when engine is idling of
with ignition turned OFF. Canada cars must
have lamps ON.
