yellowblue Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See "Wiper Blade Check" in the Maintenance Schedule booklet under Part B "Owner Checks and Services" for more information. It's a good idea to clean or replace the wiper blade assembly on a regular basis or when worn. For proper windshield wiper blade type, see "Normal Maintenance Replacement Parts" later in this section. To replace the wiper blade assembly: 1. Pull the windshield wiper assembly away from the windshield. 2. Lift the wiper blade assembly up so it is in a "T" shaped position. You should be able to see a tab. 3. Squeeze the tab together and pull the wiper blade assembly down enough to release it from the "J" hooked end of the wiper arm. Slide the assembly away from the arm. 4. Replace the blade. 6-36
