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 operate when the igni-
tion switch is in the ACCESSORY or IGNITION ON
position. The windshield wipers will return to the
parked position when the ignition switch is turned to
the OFF position. Fuses, located in the Junction
Block and Power Distribution Center protects the cir-
cuitry of the wiper system and the vehicle.
The wiper motor has permanent magnet fields. The
speeds are determined by current flow to the appro-
priate set of brushes.
The intermittent wiper system, in addition to low
and high speed, has a delay mode. The delay mode
has a range of 1/2 to 18 seconds. The wiper delay
times will double to a range of 1 to 36 seconds when
the vehicle speed is less than 10 mph. The delay is
controlled by a variable resistor in the wiper switch
and the Body Control Module (BCM). The BCM con-
trols the timing for the wiper ON/OFF, as well as the
wiper HI/LO relay.
The wiper system completes the wipe cycle when
the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.
When using the scan tool (DRB), refer to the Body
Chassis Diagnostic Manual for the procedures.
DESCRIPTION AND OPERATION
WINDSHIELD WASHERS
All models are equipped with electric operated
windshield washer pumps.
The wash function can be accessed in the OFF
position of the wiper control switch. Wash switch
must be pressed for at least 0.5 second to get the
wipe after wash. Holding the wash button depressed
when the switch is in the OFF position will operate
the wipers and washer motor pump continuously
until the washer button is released. Releasing the
button will stop the washer pump but the wipers will
complete the current wipe cycle, followed by an aver-
age of two more wipe cycles (
61) before the wipers
park and the module turns off. If the wash switch is
pressed momentarily with the wipers in the OFF or
INTERMITTENT position, a pulse wipe cycle consist-
ing of two wipes will occur.
The electric pump assembly is mounted with a
grommet directly to the reservoir. Fluid is gravity fed
from the reservoir to the motor. The fluid is forced by
the pump through rubber hoses to the hood mounted
nozzles which direct the fluid streams to the wind-
300M
