2002 Window Issues

I have a 2002 40th Anniversary Grand Prix, I was driving yesterday and noticed that the drivers back window was down a little, went to roll it up and you can hear the motor working but it is not moving the window. So I had to open the door and pull the window up. I can do just about anything, but not familiar with windows. Any suggestions? Thanks

Sounds like the cable or one of the guides for the cable may have broken in the regulator. Not a hard job once the door panel is off.
