WINDSHIELD WIPER BLADES WDI0098 CAUTION After wiper blade replacement, return the wiper arm to its original position; otherwise it may be damaged when the hood is opened. Make sure the wiper blades contact the glass; otherwise the arms may be damaged from wind pressure. Worn windshield wiper blades can damage the windshield and impair driver vision. CLEANING If your windshield is not clear after using the windshield washer or if a wiper blade chatters when running, wax or another material may be on the blade or windshield. Clean the outside of the windshield with a washer solution or a mild detergent. Your windshield is clean if beads do not form when rinsing with clear water. Clean the blade by wiping it with a cloth soaked in a washer solution or a mild detergent. Then rinse the blade with clear water. If your windshield is still not clear after cleaning the blades and using the wiper, replace the blades. REPLACING Replace the wiper blades if they are worn. 1. Lift the wiper arm away from the windshield. 2. Push the release tab, then move the wiper blade down the wiper arm to remove. 3. Remove the wiper blade. 4. Insert the new wiper blade onto the wiper arm until it clicks into place. Maintenance and do-it-yourself 8-25
