The windshield and rear window wiper and blade assembly should be inspected periodically for damage, loose components and cracked or worn blade elements. Road film can build up on the wiper blades and affect their efficiency, so they should be washed regularly with a mild detergent solution. The action of the wiping mechanism can loosen the bolts, nuts and fasteners, so they should be checked and tightened, as necessary, at the same time the wiper blades are checked. If the wiper blade elements, sometimes called inserts, are cracked, worn or warped, they should be replaced with new ones. To do this, pull the wiper blade/arm assembly away from the glass. Depress the blade-to-arm connector and slide the blade assembly off the wiper arm and over the retaining stud. Use needle-nose pliers to push in and pull out the two metal clip, then slide the old element out and slide the new element in and lock in place with the metal clip. Pinch the tabs at the end, then slide the element out of the blade assembly. Compare the new element with the old for length, design, etc. Slide the new element into place. It will automatically lock at the correct location. Reinstall the blade assembly on the arm, wet the windshield or rear window and check for proper operation.
