DESCRIPTION AND OPERATION
WINDSHIELD WIPER SYSTEM
WARNING: VEHICLES ARE EQUIPPED WITH AN
AIRBAG, REFER TO GROUP 8M, RESTRAINT SYS-
TEMS FOR STEERING WHEEL OR COLUMN SER-
VICE PROCEDURES.
DESCRIPTION
The windshield wiper system is controlled by a
switch located on the multi-functin switch stalk. The
multi-function switch is located on the steering col-
umn behind the steering wheel.
OPERATION
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.
