Someone test drove the car Friday and it rained on the way home so I never noticed. I didn't use the car until today and now NONE of the windows work!

I checked fuses and all the functions that appear to be tied in with the windows work. I hit the little butten between the drivers side switches and still nothing (presuming it's some sort of lockout switch).
I can't figure out what happened. Any suggestions ideas?
