passenger windshield wiper will not move on 2004 Pontiac Grand Am

during the big snow yesterday, my wipers started out working fine, after about 30 or so minutes of being stuck in the snow, i noticed that only my driver side was working. it is not moving at all. Any help would be great.

Check the nut that secures the wiper arm to the spindle. There should be a plastic cap that covers the nut, remove the cover and check that the nut is tight. Tighten as necessary to restore wiper arm function.
THANKS FOR THE HELP. I REALLY DIDN`T KNOW WHAT TO DO.
