INTELLIGENT POWER MODULE

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.
REAR WIPER/WASHER SYSTEM
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. DIAGNOSIS
AND TESTING
DIAGNOSIS AND TESTING - FRONT WIPER
SYSTEM
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-
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 DRB IIItscan tool. Refer to the
proper Body Diagnostic Procedures manual for DTC
descriptions 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
table.
DIAGNOSIS AND TESTING - REAR WIPER
SYSTEM
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 parkswitch) and wiper motor a Diagnostic Trouble Code
(DTC) will be stored in the BCM memory. The
DTC(s) can be retrieved using a DRB IIItscan tool.
DIAGNOSIS AND TESTING - FRONT
WIPER/WASHER SWITCH
To test the front wiper/washer portion of the multi-
function switch:
(1) Remove the multi-function switch (Refer to 8 -
ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
MULTI-FUNCTION SWITCH - REMOVAL).
(2) Using an ohmmeter check continuity reading
between switch pins. See (Fig. 1) and the table.

DIAGNOSIS AND TESTING - FAILED PARK
SWITCH
If the wiper park switch has failed the windshield
wipers will operate as follows:
²SWITCH OFF- Wipers stop in current location
regardless of the park signal.
²INTERMITTENT MODE- Wipers operate at
low speed for one or more extra wipes or continu-
ously.
