you have a clogged widshield drain on the passenger side. I had the same thing happen to mine and it was an easy fix. open the hood, remove the grating around the wipers and you will likely see standing water in a trough. sticj your hand doen there. it is remarkably deep, and clear the drain. (Watch your feet...) I had about 2 gallons of water in there.
