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).

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.
DESCRIPTION AND OPERATION
WIPER BLADES
Wiper blades, exposed to the weather for a long
period of time, tend to lose their wiping effectiveness.
Periodic cleaning of the wiper blade is suggested to
remove the accumulation of salt and road film. The
wiper blades, arms, and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the blades continue to
streak or smear, they should be replaced. The right
and left wipers are different blade lengths. The
driver side length is 525 mm and the passenger side
length is 450 mm. The blades should not be inter-
changed.

DIAGNOSIS AND TESTING
WINDSHIELD WIPER CONDITION
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
STEERING WHEEL OR COLUMN REMOVAL PROCE-
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.
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.

Using pliers or hand press the ball cap straight on to
the ball stud.
WIPER MODULE
REMOVAL
(1) Remove wiper arms and blades (Fig. 9).
(2) Remove the rear hood seal with the cowl top
plastic screen.
(3) Disconnect motor wire connector at front ple-
num wall.
(4) Remove wiper module mounting screws and
remove module.
INSTALLATION

Tighten the mounting screws to 7 to 9 N´m (60 to 80
in. lbs.) torque.
WIPER MOTOR

(1) Remove wiper module refer above.
(2) Remove linkage from motor crank. Insert
screwdriver between crank and linkage then twist
the screwdriver and lift straight up on linkage.(3) Remove motor mounting screws and remove
motor.

shroud and remove upper half of shroud (Fig. 10).
(2) Remove mounting screw on switch and remove
switch.
(3) Disconnect wire harness connector from switch.
INSTALLATION
For installation, reverse the above procedures.
CLEANING AND INSPECTION
WIPER BLADES
Wiper blades exposed to the weather for a long
period of time tend to lose their wiping effectiveness.
Periodic cleaning of the wiper blade is recommended
to remove the accumulation of salt and road grime.
The wiper blades, arms and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the wiper blades continue
to streak or smear, they should be replaced. The
wiper blade should run smoothly across the wind-
shield in both directions. The wiper blade should
slightly roll over center when the blade reverses
direction. A wiper blade insert that has lost flexibility
or a wiper arm that has lost spring tension, will
cause the blade to skip or chatter across the wind-
shield. If the wiper blades are new and the wiper

REMOVAL AND INSTALLATION (Continued)

arm spring tension is OK and a chattering sound is
emitted from the wiper(s), the wiper blade is not roll-
ing over center. If this condition exists, refer to the
Wiper Arm Alignment paragraph of this group.
ADJUSTMENTS
WIPER ARM ADJUSTMENT
(1) Cycle the wiper motor into the PARK position.
(2) Lift the wiper blade off the windshield and
release it.
(3) The wiper blade heel should be parked within 5
mm of the park line. The park line is mark on the
windshield (Fig. 11).
(4) In the event that the wiper blade tip exces-
sively strikes the cowl screen due to long term nor-
mal wear, reposition the wiper blade heel slightlyabove the park line. Make sure that the wipers are
in the PARK position.
