The windshield wiper on driver’s side of my car is limp. When I turn on the wipers, the passenger-side wiper works just fine. So much so, that it sort of crashes into the limp (and non-moving, but figitty) wiper.
Obviously, the wiper motor works just fine, since the passenger-side wiper moves. Even the driver-side wiper – while limp – does show some very minor signs of life. It doesn’t actually make it up on its own, but it does sort of move a few inches before getting rammed by the other wiper.
I noticed that there is a screw near the base of the limp wiper. Before taking my toolbox to my parked car down the street (it’s cold where I live), do you think the problem could as simple as a loose screw?
