wiper blades

As I was driving to work in a rain shower, my wiper blades stopped completely in an upright position!! This has happened once before and the blades were not catching - the motor was fine. My son fixed it at that time - but he is unavailable currently. I know it was relatively easy, but I am not sure how to proceed. HELP!!!

Check for blown wipers fuse and make sure the ground connection at the wiper motor is good.
