yellowblue Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See "Wiper Blade Check" in Section 7 of this manual under Part B "Owner Checks and Services" for more information. 1. Turn on the wipers to the low-wipe setting. 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 replacement length and type, see "Normal Maintenance Replacement Parts" in the Index. 6-44
