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. 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 length and type, see "Normal Maintenance Replacement Parts" in the Index. To replace the wiper blade assembly, do the following: 1. Turn the ignition to ACCESSORY and turn the wipers on. Position the wipers on the windshield in the "mid" wipe position. Then with a door open, turn the ignition to OFF. 2. Tip the blade up almost to a "T" position and push down on the tab to release the wiper blade assembly. 3. To install, align the wiper blade with the loop on the wiper blade assembly, and push up to snap it into place. 6-47
