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.

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 (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.

DIAGNOSIS AND TESTING (Continued)

(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.

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
STEERING WHEEL OR COLUMN REMOVAL PROCE-
DURES.
Whenever a wiper motor malfunction occurs, verify
that the wire harness is properly connected start nor-
mal diagnosis and repair procedures. Refer to Wiper
Motor Test.

DIAGNOSIS AND TESTING (Continued)

WIPER MOTOR TEST
CONDITION POSSIBLE CAUSES CORRECTION
Wiper blades do not park properly. (1) Wiper arms improperly
parked.
(2) Wiper arms are loose on
pivot shaft.
(3) Motor crank loose at output
shaft.(1) Remove wiper arms and repark.
Refer to Wiper Arm Removal and
Installation.
(2) Remove wiper arm and repark. Refer
to Wiper Arm Removal and Installation.
(3) Remove wiper arm, run wiper motor
to park position and remove the module.
Without rotating the motor output shaft,
remove the crank and clean any foreign
matter from the motor shaft. Install the
motor crank in its original position.
Motor stops in any position when
the switch is turned off.(1) Open park circuit. (1) Check park switch by disconnecting
the wire connector and apply battery
voltage to Pin 4. Place a jumper wire
from Pin 2 to Pin 3 and then to an
external ground. Replace motor if it does
not park.
Motor will not stop when the switch
is turned off.(1) Faulty switch.
(2) Lock of dynamic brake on
wet glass.(1) check switch in low, high and
intermittent position.
(2) Ensure park switch has clean ground.
Wiper blades slap against cowl
screen or window moldings.(1) Wiper arms are parked
incorrectly.(1) Park wiper arms. Refer to Wiper Arm
Adjustment.
Blades chatter. (1) Foreign substance such as
polish on glass or blades.
(2) Arms twisted, blade at
wrong angle on glass.
(3) Blade structure bent.
(4) Blade element has
permanent set.(1) Clean glass and blade element with
non-abrasive cleaner.
(2) Replace arm.
(3) Replace blade.
(4) Replace blade element.
Wiper knock at reversal. (1) Linkage bushings worn.
(2) Armature endplay in motor.(1) Replace worn link. Refer to Wiper
Linkage Removal and Installation.
(2) Replace wiper motor. Refer to Wiper
Motor Removal and Installation.
Wiper motor will not run. (1) Blown fuse.
(2) New fuse blows.
(3) New fuse blows.
(4) No Voltage at motor.
(5) Poor ground.(1) Replace fuse, and run system.
(2) Check for short in wiring or switch.
(3) Replace fuse, remove motor
connector, turn switch ON, fuse does not
blow, replace motor.

WIPER SWITCH
To test the switch, first disconnect the switch wires
from the body wiring in the steering column. Using
an ohmmeter, test for continuity between the termi-
