If your windshield is not clear af ter using
the windshield–washer or if a wiper blade
chatters when running, wax or other mate-
rial may be on the blade or windshield.

shield is clean if beads do not form when
rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer fluid or a mild deter-
gent. Then rinse the blades with clear wa-
ter. If your windshield is still not clear af ter
cleaning the blades and using the wiper,
install new windshield wiper blades.
