On the wall at the right headlight loca-
tion, place a 2 inch square piece of tape 7
inches below the horizontal line and 9 inches
to the right of the vertical centerline. This is
the target spot for the right headlight.
15
With the vehicle 25 feet from the wall
and the headlights illuminated in the low
beam position, turn the adjusting screws on
each headlight (see illustration 15.1) until
the hot spot of each headlight is centered on
it's respective target
\
spot (2 inch square
piece of tape). Note: The high beam pattern
should be correct after proper alignment of
the low beam.
16 If you cannot align either headlight, or
the light pattern on the road appears incor-
rect after adjustment, have the headlights
adjusted by a dealer service department or
other qualified repair shop at the earliest
opportunity.

19 Instrument cluster self-diagnosis
General description
1
The instrument cluster is equipped with
a self-diagnosis feature. When activated, the
electronic display, odometer/transmission
range indicator and all indicator lamps will
ill uminate in a specific sequence.
2
If the instrument cluster is not receiving
power from the CCD bus, the cluster will
appear non-functional except the airbag indi-
cator lamp will illuminate and a NO BUS mes-
sage will be displayed. If this message is dis-
played, further diagnosis should be per-
formed by a dealer service department or
other qualified repair shop.
Starting the self-diagnosis
Refer to illustrations 19.5a, 19.5b, 19.5c,
19.5d, 19.5e and 19.5f
3
While depressing the odometer/trip
reset button, turn the ignition key to the
OFF/RUN/START position.
4
This will initiate an electronic display
system check and the illumination (in
sequence) of all CCD bus activated instru-
ment cluster warning indicators. Due to the
complexity of replacing the instrument cluster
circuit board, gauges and transmission range
indicator, the home mechanic should limit
service to bulb replacement (see Section 16).
If the instrument cluster circuit board, gauge
or transmission range indicator replacement
is indicated, take the vehicle to a dealer ser-
vice department or other qualified repair shop
for service.
5
There are four check (CHEC) functions
(see illustrations):
a) CHEC 1 - Gauges: If all gauges fail to
move or do not indicate at the proper
locations, the instrument cluster circuit
board is faulty and should be replaced. If
any one gauge fails to move or indicate
properly, have it replaced.
b) CHEC 2 - Warning lamps: If any lamp
listed in Step 1 does not illuminate,
check the bulb operation. If the bulb is
OK, the instrument cluster circuit board
is faulty and should be replaced.
c) CHEC 3 - Odometer/trip meter: If any
LED does not illuminate, have it
replaced.
d) CHEC 4 - Transmission range indica-
tor/Autostick indicator: If any LED does
not illuminate, have it replaced.

Check
Refer to illustrations 21.2, 21.3 and 21.9
1
If the horn doesn't sound, check the
horn fuses in the Power Distribution Center
(PDC) and fuse block (see Section 3). If a fuse
is blown, replace it and retest. If it blows
again, there is a short circuit in the horn or
wiring between the horn and fuse block.
2
Check the circuit to the horn relay;
remove the cover from the interior fuse block.

21.3 Interior fuse block relay terminal identification
CIRCUIT
BREAKERS
Depress the horn pad on the steering wheel,
a "click" should be heard as the horn relay
activates. If the relay "clicks" proceed to
Step 7. If the horn relay cannot be heard,
remove it from the interior fuse block (see
illustration).
3
Using a fused jumper wire, connect ter-
minals 8 and 10 in the fuse block (see illus-
tration). The horns should sound.
4
Using a voltmeter, check for battery
voltage to terminals 6 and 8 in the fuse block.
Battery voltage should be present. If voltage
is not present, repair the circuit as required
(see Section 31).
5
Connect a voltmeter between terminals
6 and 7 in the fuse block. No voltage should
be present. While observing the voltmeter,
press the horn pad on the steering wheel -
battery voltage should be present when the
horn pad is depressed and absent when
released. If the voltage is not present with the
horn pad depressed, the problem exists in
the steering column wiring. If voltage is pre-
sent, replace the relay.
6
Reinstall the relay into the fuse block.
7
Check for battery voltage at the horn;
raise the front of the vehicle and support it
securely on jackstands.
8
Remove the push-in fasteners and
remove lower splash shield to access the
horn(s) electrical connectors.
9
Disconnect the electrical connector
from the discrepant horn (see illustration).
Connect a voltmeter to the wiring harness
connector and depress the horn pad on the
steering wheel. Battery voltage should be
present when the horn pad is depressed. If
no voltage is present, there is a fault in the
wiring. If voltage is present, replace the horn.
10 if no voltage is present, connect the
voltmeter positive probe to the DARK
GREEN/PINK wire and the other probe to a
good ground on the chassis. Depress the
horn pad. If battery voltage is now present,
the short exists in the ground circuit. Repair
the circuit as required (see Section 31). If
voltage is not present, the short exists in the
power circuit. Remove the horn relay from the
fuse block and using a fused jumper wire,
connect terminals 8 and 10. Battery voltage
should be present at the horn connector. If it
is, replace the relay. If no voltage is present,
repair the circuit as required (see Section 31).
11
After testing is complete, reattach the
horn electrical connector, install the splash
shield and lower the vehicle.
Removal
Refer to illustration 21.12
12
Both horns are located behind the front
bumper on the right side frame rail, one

port it securely on jackstands.
14
Remove the push-in fasteners and
remove lower splash shield.
15
Disconnect the horn electrical connec-
tor, remove the mounting bolt and withdraw
the horn from the vehicle.
Installation
16 Installation is the reverse of removal.
Check horn operation after installation.
Warning: These models have airbags. Always
disable the airbag system before working in
the vicinity of the impact sensor, steering col-
umn or instrument panel to avoid the possibil-
ity of accidental deployment of the airbag,
which could cause personal injury (see Sec-
tion 29).
Check
1
With the ignition switch ON (engine
OFF), depress the defogger switch. The indi-
cator lamp should illuminate and remain on
for approximately 10 minutes then go out. If
the indicator illuminates, the relay is opera-
tional - check the rear window defogger heat
grid (see Section 23). If the indicator lamp
fails to illuminate, either the LED light in the
switch is faulty, a short exists in the circuit or
the rear window defogger relay is faulty.
Note: The indicator will illuminate for 10 min-
utes the first time the switch is activated and
21.12 The horns (arrows) are located
behind the front bumper on the right side
frame rail, one above the other
then will only remain on for 5 minutes each
time the switch is depressed thereafter,
unless the ignition switch is turned to the OFF
position which resets the timer located inside
the Body Control Module.
2
If the indicator light fails to illuminate,
check the circuit to the rear window defogger
relay; remove the cover from the interior fuse
block. Depress the defogger switch, a "click"
should be heard as the rear window defogger
relay activates (see illustration 21.2). If the
relay "clicks" check the rear window defog-
ger heat grid (see Section 23). If the rear win-
dow defogger relay cannot be heard, remove
it from the fuse block and with the ignition
key ON (engine OFF), check for battery volt-
age to the rear window defogger relay termi-
nals 15 and 11 (see illustration 21.3). Battery
voltage should be present. If no voltage is
present, repair the circuit (see Section 31).
3
Next, connect the voltmeter between
relay terminals 13 and 15. With the defogger
switch depressed, battery voltage should be
present. If battery voltage is present, replace
the relay. If no voltage is present, repair the
circuit.
4
Remove the heater/air conditioning con-
trol assembly (see Chapter 3), but DO NOT
disconnect the electrical connectors.

With the ignition switch OFF, use an
ohmmeter to backprobe the 8-way electrical
connector RED wire (+) and the BLACK/PINK
(-) wire. Note: To backprobe an electrical
connector, use pins or paper clips inserted
into the rear of the connector (or wire) to facil-
itate meter attachment. Be careful not to
short the probes during this process.
6
Depress the defogger switch, the resis-
tance should be between 500 and 520 ohms.
If the resistance is out of tolerance, replace
the defogger switch.
7
Next, switch the multi-meter to the volts
scale and turn the ignition key ON (engine
OFF). Battery voltage should be present. If
not, repair the circuit (see Section 31).
Replacement
8
The rear window defogger switch is
incorporated into the heating/air conditioning
control assembly, refer to Chapter 3 for
replacement procedures.

Next, connect the voltmeter negative
probe to a good ground on the chassis. If the
ground circuit is OK, the reading should stay
the same. If not, repair the ground circuit (see
Section 31).
7
Connect the negative lead to terminal B,
then touch each grid line at the mid-point
with the positive lead.
8
The reading should be approximately 5
to 6 volts. If the reading is 0, there is a break
between mid-point C and terminal A.
9
A 10 to 12 volt reading is an indication of
a break between terminal B and mid-point C.
Move the lead toward the break; the voltage
will change when the break is crossed.
Repair
Refer to illustration 23.13
10
Repair the break in the heating element
using repair kit recommended specifically for
this purpose, such as Mopar Repair Kit No.
4267922 (or equivalent). Included in this kit is
plastic conductive epoxy.
11
Prior to repairing a break, turn off the
system and allow it to de-energize for a few
minutes.
12
Lightly buff the element area with fine
steel wool, then clean it thoroughly with rub-
bing alcohol.
13
Use masking tape to mask off the area
of repair (see illustration).
14
Mix the epoxy thoroughly, according to
the instructions on the package. Warning:
Read the warning instructions included with
the kit relating to the chemical component
makeup of the kit (epoxy resin and amine type
hardener) and protect yourself accordingly.
15
Follow the instructions in the kit and
apply the conductive epoxy material to the
slit in the masking tape, overlapping the
undamaged area about 3/4-inch on either
end.
16
Allow the repair to cure for 24 hours (at
room temperature) before removing the tape
and using the system.

The rear window defogger consists of a
number of horizontal elements baked onto
the inner surface of the rear window glass.
2
Small breaks in the element can be
repaired without removing the rear window.
Check
Refer to illustration 23.4
Note: When measuring the voltage at the rear
window defogger heat grid, wrap a piece of
aluminum foil around the voltmeter probes
and press the foil against the heating element
with your finger.
3
Turn the ignition switch and defogger
system switches to the ON position.
4
Working within the back seat area,
ground the negative lead of
a
voltmeter to
terminal B (lower corner passengers side)
and the positive lead to terminal A (lower cor-
ner drivers side) of the defogger grid (see
illustration).
5
The voltmeter should read between 10
and 12 volts. If the reading is lower, there is a
poor ground connection. Check the ground
connection at the right rear wheel well.
