I am having an issue with the passenger side wiper. It has lost it's mind. Seriously, I first thought the arm had come loose from the post and that explained why it went to the side and stayed there. So, I repositioned and retightened. That only resulted in it performing slowly and erratically. If it gets too far to the side it stays there. And when it stops it stops in the middle of the windshield. Sometimes it will travel all the way over the center strip. I suspect that either the brushes in the DC motor aren't making good contact, or there is something slipping or broken in the mechanical device that causes the rotational motion of the motor to translate into back and forth movement.

I'll be taking the motor out as soon as I get a chance to see what's up, but in the meantime I thought I would ask you if you had experienced anything like this, what you did, and if you had to source a new motor, from whence it came.

Thanks
