it seems like replacing the arm that connects to the car/window and the windshield wiper will be the best choice, yet i have difficulty taking it off, unbolting the hexagon bolt and the arm still won‘t budge. this arm was broken just an inch and a half away from the bolt. and as i found out, superglue is ineffective when trying to reattach this carbonfiber arm back together. advice is welcome.
Go to your local advance auto parts, Autozone, or O'reileys Auto parts and the guys behind the counter will gladly replace your wiper arm for you free of charge after buying the arm from them.
Always go with ceramic. It is A LOT better for the hair no matter how often you may use it. )
