I've had my '66 Beetle for a month now and one of the few things which as worked right is the wiper motor. I replaced the blades and tightened up one of the arms the other day -- and voila, they stopped working. I turn the switch, and they twitch just barely so I know i have power too them. But they won't move. Any thoughts on why they would be stuck? Should I just replace the unit or try a fix?
