CLEANING AND INSPECTION
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 recommended
to remove the accumulation of salt and road grime.
The wiper blades, arms and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the wiper blades continue
to streak or smear, they should be replaced. The
wiper blade should run smoothly across the wind-
shield in both directions. The wiper blade should
slightly roll over center when the blade reverses
direction. A wiper blade element that has lost flexi-
bility will not roll over properly. Or a wiper arm that
has lost spring tension will cause the blade to skip or
chatter across the windshield. If the wiper blades are
new and the wiper arm spring tension is OK and a
chattering sound is emitted from the wiper(s), the
wiper blade is not rolling over center. If this condi-
tion exists, refer to the Wiper Arm Adjustment proce-
dure in this section.
ADJUSTMENTS
WASHER NOZZLE
Right and left nozzles have three adjustable spray
juts each.
CAUTION: DURING ADJUSTMENT, BE CAREFUL
NOT TO DAMAGE INSIDE OPENING OF JET.
ASSURE PROPER VENTILATION OF ENGINE
EXHAUST.
(1) Using a safety pin, adjust each nozzle jet as
required to windshield washer spray pattern.
(2) Each adjustment of the jet should be checked
by actuating the washer system switch from inside of
vehicle.
(3) After adjustment, a final check of the spray
pattern should be done by actuating the washer sys-
tem switch from inside the vehicle with engine
idling.
This model is equipped with two hood mounted
washer nozzles. Each nozzle emits three streams into
the wiper sweep pattern. If nozzle performance is
unsatisfactory they can be adjusted. To adjust it is
recommended to use a safety pin. Insert a safety pin
into the nozzle ball and adjust the spray pattern on
the windshield as shown in (Fig. 20). The right and
left nozzles are identical.
WIPER ARM ADJUSTMENT
The wiper system does not have an indexing fea-
ture designed into the arm and blade assembly. The
arms and blades are positioned to “tic” marks on the
windshield and secured. This design allows for a
tighter fit between wiper arm and pivot shaft.
(1) Cycle the wiper motor into the PARK position.
CAUTION: AFTER CYCLING, TURN WIPER SWITCH
AND IGNITION SWITCH TO OFF.
(2) Check drivers side blade tip position is on or
between two “tic” marks on the windshield. Check
that passenger side blade edge is on or near one “tic”
mark on windshield.
(3) If requirements are not met, check for and
repair as necessary:
• bent arm or blades
• loose or worn wiper module links
• loose wiper module
• defective module mounting grommets
• defective wiper parking system
• etc
(4) Position arm and blade to “tic” marks on wind-
shield as described above and secure the wiper arm
retaining nuts.
(5) Operate system and verify proper operation. If
problem still exists, refer to Wiper System Test in
this section.
