95 Integra hatchback. At rest, the rear wiper lies in a plane parallel with the passenger side of the car. When active it pivots at the bottom and sweeps through 90 degrees until parallel with the rear bumper. Last winter I was clearing snow off the car with a broom, and accidentally dragged the wear wiper arm through it's sweep. Now when I try the wiper it sweeps a few inches but does not return. Does anyone know the fix for this? Thanks! Dave O
