Odd Problem #587 (Wipers)

You know, I've been staying out of this, but....

 I had my wipers stop moving altogether and the nut that holds the arm
on the wiper motor was loose (probably from me...). But, I can say it is
critical to position that arm correctly before tightening that nut since
it does determine the stop position. I got it wrong, and they stopped
part way up the windsheild until I fixed it.
