I haven't seen this issue posted. My wipers have about 6 inches of play if you move them while they are off. When you have them on, they slam back and forth. They will move nearly move past the window when out fully and then slam back down to the resting position over and over. It is not an issue of wiper length. I'm guessing the motor needs to be replaced as this seems to be where the extra play is comming from. Anyone had this problem, or have any knowledge on the replacement of the motor and cost?

 

Anybody changed a wiper motor out there?
