If there is noise coming from the door when you push the switch up or down, then the window regulator is the problem. If there is no noise or movement of any kind it would be the motor or the wiring leading up to the motor such as a bad switch or broken connection.
The window is not off track. The window regulator is broken. In most cases you will have to replace the window motor and regulator as an assembly.

The window regulator has failed. The new one from the dealer will come with a window motor also.
Remove the window motor from regulator. This will free the window for movement.
Usually it's either the window regulator or window motor. You can buy both online for about half of what the dealer will charge for the part. It could also be the master switch on the driver's side, but if all the other windows are working fine, I'd replace the regulator and motor. I bought the regulator with motor combo for $81 delivered recently and my window is working perfectly now.
How to remove the window motor from the regulator
Window motor and regulator are found inside of the door panel and may be bolted or riveted in. Should be bolted. Disconnect the window from regulator, take out reg. and motor, then disconnect regulator from motor, reconnect new motor to regulator, reattach those inside of the door, then reconnect the window to the regulator, put it together and see if it works.

Check the clip fron the window to the regulator. These will break off and you will hear the motor working but the window will not go up or down. You can replace your regulator and motor as one unit for little cost, if broken. You might get away with just replacing the clip to your window/regulator.
Check if there is voltage to window regulator motor; if there is replace motor.
