Just wondering if anyone had an idea of why my wipers stop in the middle of the windshield?? I've replaced the motor and switch with used one but still have the issue.

Thanks

 

Perhaps the arms that the blades are mounted to have slipped. I think there's a large srew through a bushing at the opposite end of the arm from the blade. loosen, reposition and retighten. The ones on my Maxima are friction fittings. As you tighten the bolt, the bushing is squished and bulges to tighten up in the wiper arm.
