GENERAL INFORMATION
WARNING: VEHICLES ARE EQUIPPED WITH AN AIR
BAG, REFER TO GROUP 8M, RESTRAINT SYSTEMS
FOR STEERING WHEEL OR COLUMN SERVICE
PROCEDURES.
The windshield wipers will only operated when the
ignition switch is in the ACCESSORY or IGNITION
position. A fuse, located in the fuse block, protects the
circuitry 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
done by a variable resistor in the wiper switch and
two relays. One relay turns the wipers ON/OFF and
the other changes the speeds.
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 DRB, refer to the Body Chassis
Diagnostic Manual for the procedures.
WIPER BLADES
Wiper blades, exposed to the weather for a long period
of time, tend to lose their wiping effectiveness. Periodic
cleaning of the wiper blade is suggested to remove the
accumulation of salt and road film. The wiper blades,
arms, and windshield should be cleaned with a sponge or
cloth and a mild detergent or nonabrasive cleaner. If the
blades continue to streak or smear, they should be re-
placed. The right and left wipers are different blade
lengths. The driver side length is 600 mm and the
passenger side length is 550 mm. The blades should not
be interchanged.
WIPER BLADE REPLACEMENT
(1) Turn wiper switch ON, position blades to a con-
venient place by turning the ignition switch ON and
OFF. When in position turn ignition switch OFF.
(2) Lift wiper arm to raise blade off glass.
(3) Remove blade assembly from arm by pushing
release tab under arm tip and slide blade away from
arm tip (Fig. 1 and 2). The vertabra is curved on the
right blade only. Install with the curve matching the
shape of the windshield.
(4) Gently place wiper arm tip on glass surface.
(5) For installation reverse above procedures. When
complete turn ignition switch ON. Turn wiper switch
OFF allowing the wiper blades PARK, then turn igni-
tion switch OFF.
WIPER BLADE ELEMENT REPLACEMENT
(1) Lift wiper arm to raise blade off glass.
