Windshield Wiper Blade Replacement Windshield wiper blades should be inspected for wear or cracking each time maintenace is performed. See Scheduled Maintenance on page 6-4. 1. Turn on the wipers to LO. 2. Turn off the ignition while the wipers are at the outer positions of the wiper pattern. The blades are more accessible for removal/replacement while in this position. 3. Pull the windshield wiper arm 3 to 4 inches (7.5 to 10 cm) away from the windshield. 4. While holding the wiper arm away from the glass, push the release clip from under the windshield wiper arm connecting point and slide the blade assembly down toward the glass to remove it from the wiper arm. 5. Slide the new wiper blade securely on the wiper arm until you hear the release clip click into place. For wiper blade type and length, see Normal Maintenance Replacement Parts on page 6-13 5-60
