To test the switch, first disconnect the negative
battery cable, then remove the upper and lower col-
umn shrouds to gain access to the switch connector.
Remove switch connector. Using an ohmmeter, test
for continuity (no resistance) between the terminals
of the switch as shown in the following continuity
charts (Fig. 2) and (Fig. 3).

The following is a list of general wiper motor sys-
tem problems, the tests that are to be performed to
locate the faulty part, and the corrective action to be
taken.
Whatever the problem, disconnect motor wire har-
ness and clean the terminals, then connect motor
wire harness and test.
MOTOR WILL NOT OPERATE IN SOME OR ALL
SWITCH POSITIONS
(1) Check fuse 15, in the fuse block (Fig. 1).
(a) If fuse is OK, go to Step 2.
(b) If fuse is defective, replace and check motor
operation in all switch positions.
(c) If motor is still inoperative and the fuse does
not blow, go to Step 2.
(d) If replacement fuse blows, go to Step 6.
(2) Disconnect motor wire connector.
(3) Check motor low speed. Using two jumper
wires, connect one jumper wire between the battery
positive terminal and terminal 2 of the motor connec-
tor. Connect the other jumper wire to the battery
negative terminal and the motor ground strap. Refer
to Wiper Motor Connector Pinout table and (Fig. 2).
Check motor high speed, connect the positive jumper
wire to terminal 1 of the motor connector. Connect
the negative jumper wire to the motor ground strap.
(a) If motor does not run, high or low speed go to
Step 4.
(b) If motor runs, go to Step 5.(4) Using an ohmmeter, check for good ground at
the motor ground strap. If OK, replace motor. If not
repair the ground circuit as necessary.
(5) Check terminal E of wiper switch connector for
continuity to ground. If OK, go to Step 6. If not OK,
repair the ground circuit as necessary.
(6) Using a voltmeter, with wiper switch con-
nected, connect negative lead to motor ground strap.
Connect the positive lead to terminal P1 of the wiper
switch connector (Fig. 3) and (Fig. 5).
(a) If no voltage, repair wiring as necessary. If
OK, go to Step 2.
(b) Check wiper switch low speed, connect volt-
meter positive lead to terminal L of the wiper
switch connector. Move wiper stalk to LOW posi-
tion. If no voltage, replace switch.
(c) Check wiper switch high speed, connect volt-
meter positive lead to terminal H of the wiper
switch connector. Move wiper stalk to HIGH posi-
tion. If no voltage, replace switch.
(7) Disconnect motor connector and replace fuse 15
in fuse block.
(a) If fuse does not blow, replace motor.

(b) If fuse blows, disconnect wiper switch and
replace fuse.
(c) If fuse does not blow, replace switch.
(d) If fuse blows, repair wiring as necessary.
MOTOR OPERATES SLOWLY AT ALL SPEEDS
(1) Remove wiper arms and cowl screen. Discon-
nect motor linkage from motor. Connect an ammeter
between battery positive terminal and terminal 4 of
the motor connector (Fig. 4). Turn wiper motor on
and check ampere reading.
If motor runs and ammeter reading is more than 6
amps, go to Step 2. If less than 6 amps, go to Step 3.
When replacing drive link nut tighten to 11 to 12
N´m (98 to 106 in. lbs.) torque.(2) Using an ohmmeter, check the high and low
circuits for a short to ground. Refer to Group 8W,
Wiring Diagrams.
(3) Check to see if wiper linkage or pivots are
binding or caught.
WIPERS RUN AT HIGH SPEED WITH SWITCH
IN LOW SPEED POSITION OR WIPERS RUN AT
LOW SPEED WITH SWITCH IN HIGH SPEED
POSITION.
(1) Check for crossed wires in the motor pigtail
wire connector. Refer to Group 8W, Wiring Diagrams.
(2) Check for crossed wires in harness connector
from wiper switch to motor.
(3) If OK, replace wiper switch.
WIPERS WILL OPERATE CONTINUOUSLY
WITH SWITCH IN THE INTERMITTENT
POSITIONÐWHEN WIPER SWITCH IS TURNED
OFF, WIPERS STOP WHEREVER THEY ARE,
WITHOUT RETURNING TO PARK POSITION.
(1) Check at motor ground strap for a good ground.
(2) Turn ignition switch OFF. Using an ohmmeter,
with the motor in the park position, check for conti-
nuity between terminal 3 and ground strap. If conti-
nuity, replace wiper switch. If no continuity, repair
wiring as necessary.
WIPERS DO NOT OPERATE WHEN WASHER
MOTOR IS ENGAGED (PULSE WIPE) OR
WIPERS DO OPERATE IN INTERMITTENT
POSITION.
Check for a good ground at motor ground strap and
at wiper switch terminal E. If OK, replace wiper
switch. If not OK, repair wiring as necessary.

GENERAL INFORMATION
GENERAL INFORMATION
Each vehicle is equipped with various lamp assem-
blies. A good ground is necessary for proper lighting
operation. Grounding is provided by the lamp socket
when it comes in contact with the metal body, or
through a separate ground wire.
When changing lamp bulbs check the socket for
corrosion. If corrosion is present, clean it with a wire
brush and coat the inside of the socket lightly with
Mopar Multi-Purpose Grease or equivalent.
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 and/or Daytime Run-
ning Lamp Module can result.
Do not use fuses, circuit breakers or relays hav-
ing 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.
DAYTIME RUNNING LAMP MODULE
PL vehicles built for use in Canada are equipped
with a Daytime Running Lamp (DRL) system. The
DRL system operates the headlamps at 50% illumi-
nation with the headlamp switch OFF, park brake
released and the ignition ON. The DRL system is
controlled by the Daytime Running Lamp Module.
The DRL module overrides the headlamp switch
when the headlamps are turned OFF. The headlamps
operate normally when the headlamps are turned
ON.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
When a vehicle experiences problems with the
headlamp system, verify the condition of the battery
connections, charging system, headlamp bulbs, wire
connectors, relay, high beam dimmer switch and
headlamp switch. Refer to Group 8W, Wiring Dia-
grams for component locations and circuit informa-
tion.
PLLAMPS 8L - 1

HEADLAMP DIAGNOSIS
Always begin any diagnosis by testing all of the fuses and circuit breakers in the system. Refer to Group 8W,
