Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See "Wiper Blade Check" in the Index for more information. Replacement blades come in different types and are removed in different ways. To replace the wiper blade assembly, do the following: 1. Lift the windshield wiper arm away from the windshield. 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 replacement length and type, see "Normal Maintenance Replacement Parts" in the Index. 6-43
