Windshield Wiper Blade Replacement Windshield wiper blades should be inspected for wear and cracking. See Scheduled Maintenance (Gasoline Engine) on page 6-4 for more information on wiper blade inspection. Replacement blades come in different types and are removed in different ways. To remove the type with a release clip, do the following: 1. Lift the wiper arm until it locks into a vertical position. 2. Press down on the blade assembly pivot locking tab. Pull down on the blade assembly to release it from the wiper arm hook. 3. The insert has two notches at one end that are locked by bottom claws of the blade assembly. At the notched end, pull the insert from the blade assembly. 4. To install the new wiper insert, slide the notched end last, into the end with two blade claws. Then slide the insert all the way through the blade claws at the opposite end. 5-52
