Allowing the wiper blade arm to touch the
windshield when no wiper blade is installed
could damage the windshield. Any damage
that occurs would not be covered by your
warranty. Do not allow the wiper blade arm to
touch the windshield.
3. Push the new wiper blade securely on the
wiper arm until you hear the tabs on each
side of the wiper blade assembly click
into place.
To replace the rear wiper blade, follow the steps
listed above.
