01 Windstar Rear wiper

[miles333]

The rear wiper began working erratically and has actually come loose but had fortunately not fallen off. I think I have screwed it back on properly but it does not wipe back and forth correctly, so consequently I don't use it. How do I set it to wipe correctly?

Thanks.

Make sure you dont over tighten the nut not sure on how much torqe is to be set at but your wiper in off . should be resting flat to the passanger side.at the bottom of the window. hope this helps..
