WIPER BLADES
REMOVAL
(1) Lift the wiper arm away from the glass.
(2) Disengage the release tab holding the wiper
blade to the wiper arm and remove the wiper blade
from the wiper arm (Fig. 14) and (Fig. 15).
CLEANING
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. Thewiper 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 insert that has lost flexibility
or a wiper arm that has lost spring tension, will
cause the blade to skip or chatter across the wind-
shield. 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 roll-
ing over center. If this condition exists, (refer to 8 -
ELECTRICAL/WIPERS/WASHERS/WIPER ARMS -
ADJUSTMENTS).
INSTALLATION
(1) Position the blade onto the arm.
(2) Engage the blade to the retainer by pulling up
on the blade until the tabs snap into position (Fig.
14).
WIPER BLADE ELEMENTS
REMOVAL
(1) Disengage the release tab holding the wiper
blade to the wiper arm and remove the wiper blade
from the wiper arm (Fig. 14).
(2) Disengage clip holding the wiper element to
wiper blade (Fig. 16).
(3) Pull the element from the claws on the wiper
blade.
