Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See "Wiper Blade Check in At Least Twice a Year on page 6-10 for more information. Replacement blades come in different types and are removed in different ways. For proper type and length, see Normal Maintenance Replacement Parts on page 5-105. To remove the windshield wiper blade(s): 1. Turn the wipers on to the lowest intermittent setting. 2. Turn the ignition to OFF while the wipers are at the outer position of the wipe pattern. 3. Pull the windshield wiper arm away from the windshield or backglass. 4. While holding the wiper arm away from the glass, push the release clip from under the blade. 5-58
