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:
• Continuous wipe
• Intermittent wipe
• Wash
• Wipe 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.
