We have a 2011 Juke and the Driver's side wiper does not work. The passenger side still works, and if I hold the passenger side wiper the driver's side does move. I have tried tightening the bolt with no luck. Does anyone have any other advise what may be the problem? Someone had suggested just to replace the wiper arm, but I cannot understand what that would solve, and since the driver's side does move if I hold the passenger's side, I am at a complete loss. I'm no a mechanic so my knowledge is very basic. But as we are entering the season for snow (and had our first snowfall today) I am even more concerned.
