GENERAL INFORMATION
INTRODUCTION
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAG, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
SAFETY PRECAUTIONS. DISCONNECT THE NEGA-
TIVE CABLE FROM THE BATTERY BEFORE SER-
VICING COMPONENTS INVOLVING THE AIRBAG
SYSTEM. ACCIDENTAL DEPLOYMENT OF AIRBAG
AND PERSONAL INJURY CAN RESULT.
The windshield wipers can be operated with the
windshield wiper switch when the ignition switch is
in the RUN or ACCESSORY positions. The wind-
shield wiper system is protected by a 40 amp fuse (9)
located in the Power Distribution Center (PDC) in
the engine compartment. The windshield washer cir-
cuit is protected by a 6 amp fuse (9) located in the
Junction Block. The wiper motor has permanent
magnetic fields. The speeds are determined by cur-
rent flow to the appropriate set of brushes inside the
motor. The current flow is controlled by the multi-
function switch stalk mounted wiper switch, high
speed/low speed relays located in the PDC. The speed
sensitive intermittent wiper is controlled by the BodyControl Module (BCM). The intermittent mode, with
the vehicle traveling greater than 10.4 mph, has a
range of 0.5 to 18 seconds. With the vehicle traveling
less than 10.4 mph, and the time delay is not
adjusted, time delay doubles to a range of 1 to 36
seconds. The wiper arms will park at the base of the
windshield just above the cowl cover after the wiper
switch is turned OFF.
The windshield wiper motor and linkage is located
in an integral wiper unit at the rear of the engine
compartment. The wiper unit must be removed to
gain access to the wiper motor.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
The windshield wiper system operates in several
modes:
²Low and high speed normal wipe
²Speed sensitive intermittent wipe
²Wipe after wash
²Pulse wipe
²Park (switch OFF)
The windshield wiper circuits are continuously
monitored and controlled by the Body Control Mod-
NSWINDSHIELD WIPERS AND WASHERS 8K - 1

ule (BCM). If a problem occurs in the electronic com-
ponents, wiring, switch (except integral motor park
switch) and wiper motor a Diagnostic Trouble Code
(DTC) will be stored in the BCM memory. DTC's can
be retrieved using a scan tool (DRB). Refer to proper
Body Diagnostic Procedures manual for DTC descrip-
tions and retrieval information.
The windshield wiper park switch and circuit is
monitored by the BCM. The park switch and circuit
can be tested using the Wiper System Diagnosis
chart.
FAILED PARK SWITCH
If the wiper park switch has failed the windshield
wipers will operate as follows:SWITCH OFFÐWipers stop in current location
regardless of the park signal.
INTERMITTENT MODEÐWipers operate at low
speed for one or more extra wipes or continuously.
LOW SPEEDÐWipers operate at low speed.
HIGH SPEEDÐWipers operate at high speed.
PULSE WIPEÐWipers will not operate.
WIPE AFTER WASHÐWipers operate at low
speed in any mode setting. Wipers operate only while
wash button is depressed with switch in OFF mode,
wipers stop in mid-cycle when button is released.
The windshield wiper park switch and circuit is
monitored by the BCM. The park switch and circuit
can be tested using the Wiper System Diagnosis
table.

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
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 ALIGNMENT
(1)Verify wiper blade element condition and wiper
arm spring tension. Run wipers in low speed mode
while applying water to the windshield. Observe the
wiper blade that is chattering or skipping across the
windshield. If the wiper element is not rolling over
when the wiper direction reverses, align the wiper arm.
The extension bar portion of the wiper arm must be
twisted in the proper direction to allow the wiper ele-
ment to roll over when the direction reverses.
(2) Place two small adjustable wrenches placed 50
mm (2 in.) apart on the wiper arm extension rod.
(3) Twist the extension rod slightly in the opposite
direction that the element is laying on the wind-
shield while holding the wrench closest to the pivot
stationary.
(4) Repeat step Step 1, and align as necessary
until wiper stops chattering and wipes the wind-
shield clear.

DESCRIPTION AND OPERATION
INTRODUCTION
When continuous rear wiper operation is required,
the Body Control Module (BCM) will provide ignition
ON voltage to the rear wiper motor. When the wiper
switch is turned OFF, the BCM provides circuit
ground to operate the motor until the wipe cycle is
complete and the wiper arm returns to the base of
the rear window.
When intermittent rear wiper mode is selected, the
wiper motor will cycle every 7 seconds. The intermit-
tent delay time is also adjusted based upon vehicle
speed. With the vehicle traveling greater at 50 mph,
the cycle changes to every 5 seconds.
REAR WINDOW WIPER/WASHER SWITCHES
The rear window wiper/washer switches are incor-
porated into the HVAC switch panel. Refer to Group
8E, Instrument Panel for proper service procedures.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
The rear window wiper system operates in several
modes:
²Continuous wipe
²Intermittent wipe
²Wash
²Wipe after wash
The windshield wiper circuits are continuously
monitored and controlled by the Body Control Mod-
ule (BCM). If a problem occurs in the electronic com-
ponents, wiring, switch (except integral motor park
switch) and wiper motor a Diagnostic Trouble Code
(DTC) will be stored in the BCM memory. The
DTC(s) can be retrieved using a scan tool (DRB).
Refer to proper Body Diagnostic Procedures manual
for DTC descriptions and retrieval information.
