wiper on 2004 Hyundai Tiburon

After the snow storm this week my drivers side wiper is not working but the passenger side works fine. When I move it manually it moves freely. What could it be?

The nut that holds the wiper arm to the motor may be loose. Try tightening the nut, if it's not loose, then the moor or linkage may be broken.
