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.
