Other information:
Raise the wiper arm off the rear
window.
Turn the wiper blade assembly counterclockwise.
Pull the wiper blade assembly toward
you to remove it from the wiper arm.
Install the wiper blade assembly to the
wiper arm. Make sure that it locks in place...
Grease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation and streaking on the
glass. If you cannot remove the streaks
after operating the windshield washer or if
the wiper operation is jerky, clean the outer
surface of the windshield (or rear window)
and the wiper blades using a sponge or
soft cloth with a neutral detergent or mildabrasive
cleaner...
anytime you want.
