key ON and the
multi-function
lever
in its UP or
DOWN position, current flows
through
the:
• turn signal flasher canister • Turn/Hazard switch
• turn indicator lamp
• front
and
rear bulbs. The selected turn signal indicator with front
and

rear turn signal bulbs will flash.
DIAGNOSIS High generator output voltage
can
burn
out

lamps rapidly. (1) Remove
and
inspect fuse
in
cavity
#9 of
fuse
block. Replace
if
necessary.
The
fuse block
is
behind
the lower instrument panel cover under steering wheel. (2) Turn
key to
ACCY. There should
be
battery
voltage
at the
fuse side
of the
turn signal flasher (bottom terminal).
If
not,
repair open circuit
in
wir­
ing between fuse
and
flasher.
(3) Replace Turn Flasher with
2
lamp
12
volt rated
flasher that
is
know
to be
good.
The
lamps should
flash. If
not,
replace with original flasher
and
go to

next step.
(4) Measure voltage
at the
Turn/Hazard switch
connector cavity
#17.
Meter should read battery volt­

age.
If
OK,
replace Turn/Hazard switch assembly.
If

not, repair open circuit
in
wiring between flasher
and Turn/Hazard switch connector.
HAZARD WARNING SYSTEM

DESCRIPTION
With
the
hazard switch
OUT,

two
rear turn signal bulbs
• both indicator bulbs.
All
of the
turn lamps
and
both indicators will
flash.
DIAGNOSIS Hazard switch
in
ON.
The
park
and
stop lamps
should light.
If
not
replace
the 20
amp
fuse
in
fuse
block cavity
#13.

(1) Measure voltage
at
the
fuse side
of
the
flasher
(side terminal). Meter should read battery voltage.
If

not, repair open circuit
in
wiring
to
fuse. (2) Replace Hazard flasher with known good
flasher. Lamps should flash.
If
not, replace with orig­
inal flasher
and go
to
next step.
(3) Measure voltage
at the
Turn/Hazard switch
connector cavity #13. Meter should read battery volt­

age.
If
not,
repair open circuit
in

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
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.

• (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.
