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. 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. A. Taillamp Bulb B. Back-Up Lamp Bulb C. Turn Signal Lamp Bulb D. Stop/Taillamp Bulb 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. 6. Snap the bulb holder back into place, making sure all retaining tabs are properly over the bulb holder tabs. 7. Reinstall the taillamp assembly by inserting the outboard locating/retaining pins until the lamp is seated. Secure with the inboard screws. For any bulb changing procedure not listed in this section, contact your dealer's service department. 6-38
