REMOVAL

CAUTION: Do not apply pressure to, or pry on, the plastic drive link bushing. When removing the drive link
from, or installing the drive link to the ball stud on the wiper motor crank arm, apply pressure to, or pry on,
only the metal portions of the drive link around the bushing. If the bushing is damaged, the entire front
wiper module MUST be replaced.

CAUTION: Do not remove the crank arm nut from the wiper motor output shaft. The crank arm is indexed to
the output shaft with the motor in the park position during the manufacturing process, but there are no
provisions made for correctly indexing this connection in the field. If the crank arm to output shaft indexing
is incorrect, the entire front wiper module MUST be replaced.

1. Disconnect and isolate the battery negative cable.

2. Remove both front wiper arms from the wiper piv-

ots. (Refer to 8 - ELECTRICAL/FRONT WIPERS/
WASHERS/FRONT WIPER ARMS - REMOVAL).

3. Remove the cowl plenum cover/grille panel from

over the front wiper module. (Refer to 23 - BODY/
EXTERIOR/COWL

GRILLE

AND

SCREEN

REMOVAL).

4. Disconnect the wire harness connector from the

front wiper motor connector.

5. Disengage the socket bushing (3) of the right wiper

drive link (2) from the ball stud on the wiper motor
crank arm (5) using two large screwdrivers, one on
each side of the ball stud. Pry between the crank
arm and the metal portion of the drive link until the
socket unsnaps from the ball.

6. Remove the sleeve bushing of the left wiper drive

link (4) from the ball stud on the wiper motor crank
arm.

7. While supporting the wiper motor (7) from the underside of the wiper module bracket (6), remove the three

screws (1) that secure the motor to the bracket.

8. Remove the wiper motor and crank arm unit from the underside of the module bracket.

INSTALLATION

FRONT WIPERS/WASHERS - SERVICE INFORMATION

1. Position the front wiper motor (7) and crank arm (5)

unit from the underside of the front wiper module
bracket (6).

2. Install and tighten the three screws (1) that secure

the motor to the bracket. Tighten the screws to 7
N·m (62 in. lbs.).

3. Position the left wiper drive link (4) sleeve bushing

onto the ball stud on the end of the motor crank
arm.

4. Position the socket bushing (3) of the right wiper

drive link (2) over the ball stud on the crank arm.

5. Place a short 19 millimeter or 3/4 inch socket over

the capped side of the bushing as an installation
tool. Then use large channel-lock pliers to apply
enough pressure to the underside of the crank arm
and the top of the socket to snap the bushing onto
the ball stud. Do not apply pressure directly to
the plastic bushing.

6. Reconnect the wire harness connector to the wiper motor connector.

7. Reinstall the cowl plenum cover/grille panel over the front wiper module. (Refer to 23 - BODY/EXTERIOR/COWL

GRILLE AND SCREEN - INSTALLATION).

8. Reconnect the battery negative cable.

9. Turn the ignition switch to the On position, then turn the front wiper switch On and Off again to cycle the wiper

motor and linkage to their natural park positions before reinstalling the front wiper arms onto the wiper pivots.

10. Reinstall both front wiper arms onto the wiper pivots. (Refer to 8 - ELECTRICAL/FRONT WIPERS/WASHERS/

FRONT WIPER ARMS - INSTALLATION).

NOZZLE-WINDSHIELD WASHER

DESCRIPTION

The fluidic front washer nozzles (2) are constructed of
molded plastic. Each nozzle has two integral latches
that secure them in dedicated holes in the hood panel
near the base of the windshield. A check valve is inte-
gral to each front washer nozzle. The domed upper
surface of the washer nozzle is visible on the outside
of the hood panel, and the nozzle orifice (1) is ori-
ented towards the windshield glass. The washer
plumbing fittings (4) for the washer nozzles extend
below the hood panel and are accessible from the
engine compartment. The front washer nozzles cannot
be adjusted or repaired and, if faulty or damaged, they
must be replaced.

OPERATION

The two front washer nozzles are designed to dispense washer fluid into the wiper pattern area on the outside of
the windshield glass. Pressurized washer fluid is fed to each nozzle from the washer reservoir by the washer pump/

FRONT WIPERS/WASHERS - SERVICE INFORMATION

8R - 49

motor unit through a single hose, which is attached to a barbed nipple on each washer nozzle below the hood
panel. A fluidic matrix within the washer nozzle causes the pressurized washer fluid to be emitted from the nozzle
orifice as an oscillating stream to more effectively cover a larger area of the glass to be cleaned.

The integral check valve prevents washer fluid from draining out of the washer supply hoses back to the washer
reservoir. This drain-back would result in a delay from when the washer pump is energized until washer fluid was
dispensed through the nozzles. Such a drain-back condition could also result in water, dirt, or other outside con-
taminants being siphoned into the washer system through the washer nozzle orifice. This water could subsequently
freeze and plug the nozzle, while other contaminants could interfere with proper nozzle operation and cause
improper nozzle spray patterns.

When the washer pump pressurizes and pumps washer fluid from the reservoir through the washer plumbing, the
fluid pressure unseats a diaphragm from over a sump well within the nozzle. With the diaphragm unseated, washer
fluid is allowed to flow through the washer nozzle. When the washer pump stops operating, the diaphragm seats
over the sump well in the valve and fluid flow in either direction within the washer plumbing is prevented.

REMOVAL

1. Insert a trim stick or another suitable wide flat-

bladed tool between the front or rear edge of the
washer nozzle (1) and the hood panel (2) to
depress one of the nozzle latches.

2. Holding the latch depressed, lift upward on the

same edge of the nozzle to disengage it from the
hood.

3. Pull the nozzle away from the hood far enough to

access and disconnect the hose from the barbed
nipple of the nozzle.

4. Remove the nozzle from the top of the hood panel.

INSTALLATION

1. Position the front washer nozzle (1) near the

mounting hole on the outside of the hood panel (2).

2. Reconnect the washer hose to the barbed nipple of

the nozzle.

3. Insert the nozzle into the mounting hole.

4. Using hand pressure, push firmly and evenly on

the top of the nozzle until the integral latches lock
into place on the underside of the outer hood
panel.
