GENERAL
INFORMATION Each vehicle is equipped with various lamp assem­

blies.
A good ground is necessary for proper lighting operation. When changing lamp bulbs check the socket for
corrosion. Clean corrosion with a wire brush. Coat
the inside of the socket lightly with Mopar® Multi- Purpose Grease or equivalent.

DIAGNOSTIC
PROCEDURES
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. Refer to Group 8W, Wiring Diagrams. Conventional and halogen headlamps are inter­
changeable. It is recommended that they not be in­
termixed on a given vehicle.

MULTI-FUNCTION
SWITCH TESTING
PROCEDURES
The multi-function switch contains electrical cir­
cuitry for:
• Headlamp Dimmer Switch
• Passing Lights
• Turn Signals
• Hazard Warning • Windshield Wiper

HEADLAMP
ALIGNMENT
Headlamps
can be
aligned using
the
screen method
provided
in
this section. Alignment Tool C4466-A
or

equivalent
can
also
be
used. Refer
to
instructions
provided with
the
tool
for
proper procedures.
The
preferred headlamp alignment setting
is 0 for

the left/right adjustment
and
1" down
for the up/
down adjustment.

HEADLAMP
ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch
and
high beam
indicator operation. (2) Correct defective components that could hinder
proper headlamp alignment. (3) Verify proper tire inflation. (4) Clean headlamp lenses.
(5) Verify that luggage area
is not
heavily loaded.
(6) Fuel tank should
be
FULL.
Add 2.94 kg (6.5

lbs.)
of
weight over
the
fuel tank
for
each estimated
gallon
of
missing fuel.

away from front
of headlamp lens.
(2)
If
necessary, tape

• (3) Up 1.27 meters (5 feet) from the floor, tape a
line on the wall at the centerline of the vehicle.
Sight along the centerline of the vehicle (from rear of
vehicle forward) to verify accuracy of the line place­
ment.
(4) Rock vehicle side-to-side three times to allow
suspension to stabilize. (5) Jounce front suspension three times by pushing
downward on front bumper and releasing. (6) Measure the distance from the center of head­
lamp lens to the floor. Transfer measurement to the alignment screen (with tape). Use this line for up/
down adjustment reference.
(7) Measure distance from the centerline of the ve­
hicle to the center of each headlamp being aligned. Transfer measurements to screen (with tape) to each side of vehicle centerline. Use these lines for left/
right adjustment reference.

HEADLAMP
ADJUSTMENT
A properly aimed low beam headlamp will project
top edge of high intensity pattern on screen from 50 mm (2 in.) above to 50 mm (2 in.) below headlamp
centerline. The side-to-side outboard edge of high in­
tensity pattern should be from 50 mm (2 in.) left to 50 mm (2 in.) right of headlamp centerline (Fig. 1).
The preferred headlamp alignment is 0 for the
up/down adjustment and 1" down for the left/
right adjustment. The high beam pattern should be correct when the iow beams are aligned properly (Fig. 2).
To adjust headlamp aim, rotate alignment screws
to achieve the specified high intensity pattern.
