DESCRIPTION AND OPERATION
WASHER NOZZLE
This model is equipped with two hood mounted
washer nozzles. Each nozzle emits two streams into
the wiper pattern (Fig. 1). If the nozzle performance
is unsatisfactory they can be adjusted. To adjust
insert a pin into the nozzle ball and move to proper
pattern (Fig. 2). The right and left nozzles are iden-
tical.
DIAGNOSIS AND TESTING
WINDSHIELD WASHERS
All models are equipped with electric operated
windshield washer pumps.
The wash function can be accessed in the OFF
position of the wiper control switch. Holding the
wash button depressed when the switch is in the
OFF position will operate the wipers and washer
motor pump continuously until the washer button is
released. Releasing the button will stop the washer
pump but the wipers will complete the current wipe
cycle. Followed by an average of two more wipe
cycles (61) before the wipers park and the module
turns off.
Whenever a windshield washer malfunction occurs,
first verify that the windshield washer wire harness
is properly connected to all connectors before starting
normal diagnosis and repair procedures. Refer to
Windshield Washer Test Table.
The electric pump assembly is mounted directly to
the reservoir. A permanently lubricated motor is cou-
pled to a rotor type pump. Fluid, gravity fed from the
reservoir, is forced by the pump through rubber hoses
to the hood mounted nozzles which direct the fluid
streams to the windshield.
The pump and reservoir are serviced as separate
assemblies (Fig. 3).

GENERAL INFORMATION
INTRODUCTION
WARNING: VEHICLES ARE EQUIPPED WITH AN
AIRBAG, REFER TO GROUP 8M, RESTRAINT SYS-
TEMS FOR STEERING WHEEL OR COLUMN SER-
VICE PROCEDURES.
The windshield wipers will only operate with the
ignition switch in the ACCESSORY or IGNITION
RUN position. The wiper circuit is protect against
over loads by a fuse in the fuse block and a circuit
breaker within the wiper motor. This protects the cir-
cuitry of the wiper system and the vehicle.
The wiper motor has permanent magnet fields.
The intermittent wiper system, in addition to low
and high speed, has a delay mode and a pulse wipe
mode. The delay mode has a range of 1 to 15 seconds.
Pulse wipe is accomplished by momentarily moving
the stalk lever into the WASH position while the
wiper switch is in either OFF or DELAY position.
The wiper blades then sweep once or twice and
return to the previous wiper switch mode, OFF or
DELAY.
The intermittent wiper function is integral to the
wiper switch. All electronics and relay are inside the
switch assembly.
The wiper system completes the wipe cycle when
the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.

DURES.
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.

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.

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.
