Re: Issues with rear wiper
From your description, I would guess that your wiper arm is not set to the wiper motor range.
By this I mean the motor only knows to operate one direction to a point and then return the other direction to the starting point and repeat until you turn it off. So, if the wiper arm base is set on the motor in the wrong position, this will cause the wiper arm to operate in the wrong area. I believe there is a attachment nut on the base, that nut may also have got loose and let the wiper arm slide over a few inches.
If the wiper motor IS working, then you can rule out a motor issue. It would be more of a setting issue with the wiper arm and its attachment to the motor base.
Hope this helps.
