Signs a wiper arm may need replacing include a blade that no longer presses firmly against the glass, a blade that skips or chatters across the windshield, and an arm that is bent or loose on its pivot. Diagnose the cause first, because a worn blade or the wiper linkage can also cause some of these symptoms.
