The windshield 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, the blade assemblies should be replaced with new ones. Pull the wiper blade/arm assembly away from the glass.For front wiper blades, to remove the wiper blades: On early models, lift the release lever and slide the blade assembly off the wiper arm and over the retaining stud. The blade/element assembly must be replaced as a unit. On later models, lift the wiper arm assembly away from the glass for clearance, press the release lever then slide the wiper-blade assembly out of the hook at the end of the arm. For rear wiper blades, to remove the wiper blades: On early models, follow the procedure as mentioned for front wiper blades. The blade/element assembly must be replaced as a unit. On later models, lift the wiper arm assembly away from the glass for clearance, swing the wiper blade (arm side) away from the wiper arm to its fullest travel. Press the blade (arm side) against its stop on the wiper arm to unsnap the wiper blade pivot pin from the latch on the underside of the wiper arm. For all wiper blades, compare the new blade assembly to the old one for length, design, etc. Reinstall the blade assembly on the arm, wet the windshield and check for proper operation.
