Windshield Wiper Blade Replacement Windshield wiper blades should be inspected for wear or cracking. See Owner Checks and Services on page 6-9. 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 on page 6-15. To replace the wiper blade assembly, do the following: 1. Turn the ignition to ON with the engine off. 2. Turn on the windshield wipers and turn them off again when the wipers are in the out-wipe position. The driver's side blade will be straight up and down on the windshield. 3. Pull the windshield wiper assembly away from the windshield.
