The windshield wiper arm connects to the wiper linkage and holds the blade. Over time, the arm can get bent and damaged, especially during the winter when it’s moving heavy snow and ice. If the windshield wiper arm is going bad, you’ll know right away because the wiper will leave streaks, chatter across the windshield, or not move at all.
