Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See "WiperBlade Cheek" under Pari B: Owner Checks and Services on page 6-9 for more information. To replace the wiper blade assembly do the following: 1. Lift the wiper up from the windshield and set it into the vertically-locked position. 2. 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. 3. Remove the blade. 4. 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. For the proper windshield wiper blade assembly replacement length and type, see Normal Maintenance Replacement Pan's on page 5- 101. 5-59
