GENERAL INFORMATION
All models are equipped with electric operated
windshield washer pumps. The wash function can be accessed in the OFF po-
sition of the wiper control switch. Holding the wash
button depressed when the switch is in the OFF po-
sition will operate the wipers and washer motor
pump continuously until the washer button is re-
leased. Releasing the button will stop the washer
pump but the wipers will complete the current wipe
cycle. Then 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 Diagnosis Chart (Fig. 29). The electric pump assembly is mounted directly to
the reservoir. A permanently lubricated sealed motor
is coupled to a rotor type pump. Fluid, gravity fed
from the reservoir, is forced by the pump through
rubber hoses to the nozzles which direct the streams
to the windshield. The pump and reservoir are serviced as separate
assemblies on all vehicles.

REMOVAL
(1) Remove cowl top screen on applicable models
(Fig. 30 through 33) (2) Remove sheet metal screws attaching the reser-
voir in plenum.

HEADLAMP SWITCH
Service procedures for the headlamp switch can be
found in Group 8E, Instrument Panel and Gauges. More
information can be found in Wiring Diagrams manual.
HEADLAMP DIMMER SWITCH
The headlamp dimmer switch is incorporated into
the turn signal switch. Proper procedures can be found
in Group 8J, Turn Signal and Flashers. More informa-
tion can be found in Group 8W, Wiring Diagrams.
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 0 for the up/down ad-
justment.
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation. (2) Inspect and correct damaged or defective compo-
nents that could interfere with proper headlamp align-
ment. (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.
HEADLAMP ADJUSTMENT USING ALIGNMENT
SCREEN
ALIGNMENT SCREEN PREPARATION (FIG. 1 AND 2)
(1) Position vehicle on a level surface perpendicular
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.
(3) From the floor up 1.27 meters (5 ft), 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 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) 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 (FIG. 3, 4, 5, 6 OR 7)
A properly aimed low beam headlamp will project the
top edge of low beam hot spot on the alignment screen
from 50 mm (2 in.) above to 50 mm (2 in.) below the
headlamp centerline. The side-to-side left edge of low
beam hot spot should be from 50 mm (2 in.) left to
50mm (2 in.) right of headlamp centerline (Fig. 1). The
preferred headlamp alignment is 0 for the
up/down adjustment and 0 for the left/right ad-
justment. 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.
CAUTION: Do not cover an illuminated headlamp for
more then 15 seconds. Lamp will overheat and burn
or melt cover.
To adjust headlamps, rotate alignment screws to
achieve the specified high intensity pattern (Fig. 1 or
2).
FOG LAMP ALIGNMENT (FIG. 8)
Prepare an alignment screen. Refer to Alignment
Screen Preparation paragraph in this section. A prop-
erly aligned fog lamp will project a pattern on the
alignment screen 100 mm (4 in.) below the fog lamp
centerline and straight ahead.
