Hey guys, I don't know what's wrong with my wiper arm. Its just drooping, every time I bring the arm up it droops down. If you turn on the wiper you could here a buzz but it doesn't work. If you lift it up while the wiper setting is on you could feel it fighting to move but it can't. I don't know what's wrong with it, don't know if it's the motor inside. Do you guys think this is a easy fix? I really don't want to take it to the dealer.
