Windshield wiper blades should be inspected periodically for wear and cracking. See Scheduled Maintenance .

Replacement blades come in different types and are removed in different ways. For proper type and length, see Maintenance Replacement Parts .

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.
