In the press-type button method, a red-colored button is depressed to release the rubber element. The old element can be slid off and a new one can be slid into place. Once centered, it will lock into place.

The windshield wiper motor also serves as the drive system for the windshield washers.

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, they should be replaced with new ones. On 1995 and earlier models, remove the wiper blade assembly from the wiper arm by using a small screwdriver to lift the release lever while pulling on the blade to release it. On 1996 and later models, lift the arm assembly away from the glass for clearance, press on the release lever, then slide the wiper blade assembly out of the hook in the end of the arm. With the blade removed from the vehicle, you can remove the rubber element from the blade. Using pliers, pinch the metal backing of the element, 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 glass, and test for proper operation.

From 1974 to 1977, first remove the left-hand control panel far enough to remove the attaching screws. Then, pull out the knob, disconnect the wiring and remove the switch. From 1978 to 1980, disconnect the negative battery cable and remove the instrument cluster trim panel. Finally, remove the 2 mounting screws and remove the switch from the rear.

To reinstall the wiper arm/blade assembly, you simply need to reverse the removal process. Make sure that the connector is fully pushed onto the arm and that the small locating 'pip' securely fits into the hole in the connector.
