Wiper Arm: Description and Operation

The Wiper Arms connect the wiper pivots and the wiper blades. They feature an over-center hinge that allows easy access to the windshield glass for cleaning and service operations. A molded black plastic cap fits over the Wiper Arm attachment nut for protection. The Wiper Arm cannot be adjusted or repaired. If faulty or damaged, the entire wiper arm must be replaced.
