Windshield wipers have two primary components: the wiper blade which clears the windshield, and the wiper arm which holds the blade and moves it across the glass. The wiper arm contains a pivot that attaches to the wiper motor transmission, a spring that pulls the wiper blade snugly against the glass, and an attachment point at the end to connect a wiper blade. It’s essential to know whether your issue is with the arm itself or just the blade.
