yellowblue Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear and cracking. See "Wiper Blade Check" in Section 7 of this manual under Part B "Owner Checks and Services" 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" in the Index. Here's how to remove the Sheperd's Hook type: 1. Turn the wipers on to the lowest intermittent setting. 2. Turn off the ignition while the wipers are at the outer positions of the wipe pattern. The blades are more accessible for removal/replacement while in this position. 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 connecting point and pull the blade assembly down toward the glass to remove it from the wiper arm. 5. Push the new wiper blade securely on the wiper arm until you hear the release clip "click" into place. 6-38
