DESCRIPTION AND OPERATION
WINDSHIELD WASHER NOZZLE(S)
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 identical.
WINDSHIELD WASHER SYSTEM
All models are equipped with electrically 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.
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).

(1) Raise vehicle on hoist.
(2) Disconnect the wire connector from the reser-
voir pump.
(3) Disconnect the washer hose at the pump and
drain the reservoir.
(4) Gently pry pump away from reservoir and out
of grommet. Care must be taken not to puncture res-
ervoir (Fig. 6).
(5) Remover rubber grommet from reservoir. If
replacing the pump, discard the old washer pump
grommet. If replacing the reservoir only, reuse the
old washer pump grommet.
INSTALLATION
For installation, reverse the above procedures.
Make sure to use new grommet when installing new
washer pump.

DESCRIPTION AND OPERATION
DIAGNOSTIC PROCEDURES
When a vehicle experiences problems with the
headlamp system, verify the condition of the battery
connections, fuses, charging system, headlamp bulbs,
wire connectors, relay, high beam switch, dimmer
switch, and headlamp switch. Refer to Group 8W,
Wiring Diagrams for component locations and circuit
information.
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. Turn
signal lamp circuitry always comes from the multi-
function switch, and goes to the cluster connector,
into the cluster, then back out to the front turn sig-
nal switch lamps. The Canadian cluster provides
steady illumination of the front turn signal when the
ignition switch is in the ON position. The DRL func-
tion may be inhibited by activating the turn signals,
the hazard flashers, the headlamp switch, or park
brake.
DIAGNOSIS AND TESTING
HEADLAMP DIAGNOSIS
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
intermixed on a given vehicle.

DESCRIPTION AND OPERATION
HEADLAMP ALIGNMENT
Headlamps and Fog Lamps should be aligned
using the screen method which is provided in this
section.The preferred headlamp alignment set-
ting is 0 for the left/right adjustment and 0 for
the up/down adjustment.
SERVICE PROCEDURES
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Inspect and correct damaged or defective com-
ponents that could interfere with 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.
ADJUSTMENTS
HEADLAMP ADJUSTMENT USING ALIGNMENT
SCREEN
ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicu-
lar to a flat wall 7.62 meters (25 ft.) away from front
of headlamp lens.
(2) If necessary, tape a line on the floor 7.62
meters (25 ft.) away from and parallel to the wall
(Fig. 1).(3) From the floor up 1.27 meters (5 ft.), tape a
line on the wall at the center line of the vehicle.
Sight along the center line of the vehicle (from rear
of vehicle forward) to verify accuracy of the line
placement.
(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) A small dot is molded into each headlamp lens
signifying the center of the headlamp. Measure the
distance from the center of the headlamp to the floor.
Transfer measurement to the alignment screen (with
tape). Use this line for up/down adjustment refer-
ence.
(7) Measure distance from the center line of the
vehicle to the center of each headlamp being aligned.
Transfer measurements to screen (with tape) to each
side of vehicle center line. Use these lines for left/
right adjustment reference.
HEADLAMP ADJUSTMENT
The PL headlamp low beam pattern has a distinct
horizontal cutoff line which is used to visually align
the headlamps. A properly aimed headlamp will have
the horizontal cutoff line of the low beam pattern
centered on the low beam pattern centered on the
horizontal center of headlamp line. The side to side
left edge of the low beam hot spot should be located
75 mm (3 inches) to the left of the headlamp center
line (Fig. 1). The high beams on a vehicle with aero
headlamps cannot be aligned. The high beam pattern
should be correct when the low beams are aligned
properly.
To adjust headlamp alignment, rotate alignment
screws to achieve the specified low beam hot spot
pattern.
