Century windshield wipers only work on high

[2k2cse]

After digging my car out from a snowstorm Sunday, I tried turning on the wipers to get the last bit of snow off the windshield.. the wipers would only come on when the switch was on "high." Even when on "mist," or when I try using the washer fluid, they don't work.. the washer fluid does come out when I turn it on though. Also, they don't always park properly.. They usually stop wherever they are when I move the switch out of high. If its at or near the bottom of the windshield, then they will "park" properly.

 

Any ideas what could be causing this? Could it just be the multifunction switch, or could it be something simple/cheaper?
