200 TQW wipers

[Lawson, Dave]

I am wondering if anyone knows how to reset the stop point
for the wipers on my 1990 200 TQ wagon. In the rain and snow
over the past few days, the wiper stop point has changed from
its normal park position, to gradually moving across the windshield.
At this point the wiper is parked at about a 60 degree angle,
conveniently right in the drivers line of vision. I have played with 
the interrmitent and on positions and turned the car off to try and 
get it to reset, but no luck.

Any BTDT on getting the wipers back to the normal park position
would be greatly appreciated.
