DESCRIPTION AND OPERATION (Continued)
WIPER BLADES
When the wiper blade rubber element is exposed to
the weather for a long period of time, it tends to lose
wiping ability. Periodic cleaning of the wiper blade
element 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 non-abrasive cleaner. If the
blades continue to streak or smear, they should be
replaced. The driver and the passenger blade ele-
ments are 550 mm in length. Only the driver's side
wiper blade has a air foil on it (Fig. 2).
