out of the blue, my 2000 grand prix driver's window failed to come back up. The motor and all other parts are functioning, but I have a cable loose and flopping around.....help!

This is almost certainly because the door window regulator has failed, and it will probably need to be replaced. You can get an estimate for having this done at a shop in RepairPals' estimator.
