The other day it was raining very heavy and the windshield wipers
worked fine until  I parked and hurried out the car leaving the wipers
in the on position.  The wipers did position itself in the middle of
the windshield to remind me it is being left in the on position, but I
just left them that way and ran thru the rain.  When I returned to the
car a few hours later the wipers would not return to home horizontal
position; at the bottom of the windshield.   Instead it would
terminate at the center vertical position no matter what setting it is
on, or even when I shut it off.

I would like to know if there is an easy fix for this problem or if
anyone had this problem b4 and know the fix for it.  Any help is
appreciated, thank you!
