I have had the car for three years now, and every winter my wipers get stuck in the up position. The first time it happened they were frozen on the winshield, and did not move when engaged. I have had them fixed. In winter of 2007 it happened again, this time I was careful and made sure they weren't frozen to the winshield. On the way to the dealer for my appointment, I turned them on and the problem corrected itself. December 2008, I was using the wipers becasue of rain and noticed that they shifted funny. When I turned the wipers off, they remained in the upright position. The dealer told me the first time that the bars were all bent on the rail. Last week I looked into the rail system myself and noticed the bars are like pieces of cunduit. Nothing looked bent. Why does this happen every winter?? My rear defroster seems to work off and on in the winter also. Somedays it will not melt the snow on the rear window. Frustrating!!

 

From ZSPOT
There should be a little metal tab by the crank arm of your wiper transmission that probably got bent. The park switch tells the wiper transmission where to park, if that tab is bent, it parks the transmission in the opposite direction. I think that should work for you.
