Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See "Wiper Blade Check" under Part B: Owner Checks and Services on page 6-19 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 5-101. To replace the wiper blade assembly, do the following: 1. Position the wipers on the windshield in the "mid" wipe position. 2. Lift the windshield wiper arm away from the windshield. The windshield wiper does not have a locking upright position feature. 3. Push the tab on the wiper blade assembly and pull the assembly down enough to release it from the U-hooked end of the wiper arm. Slide the assembly away from the arm. 4. Replace the blade. 5. To reinstall the wiper blade assembly, slide it over the wiper arm to engage the U-hooked end on the wiper blade assembly. Pull up on the assembly to lock it into place. 5-57
