You might try putting the wipers in "service position" and see if that resets things:
Turn on ignition (or press button so radio etc comes on). Wait a few seconds then turn off. Now (within 3 seconds) press down the wiper stalk (as though you are doing a single wipe). Hold down for a couple of seconds. Wipers should now move into the service position in the middle of with windshield. They will return to regular position when you next start the car. This is also how you change the wiper blades.
