Tom,

If the fuse is good and the switch is wired correctly, then it could be a broken gear, bad motor, or bad wiring.

If the motor hasn't been run in a very long time, the grease on the worm gear shaft will harden (or the shaft rusts). This increases the torque required to rotate the shaft, and the stock motors don't have much torque. With the door panel removed, try rotating the rubber motor coupling by hand. Try both directions to see if it will free up. If it won't rotate, then you will need to remove the window regulator from the door and remove the gear cover.
