This problem is either due to a failed window regulator or failed window motor. If you operate the switch and listen carefully to the door can you hear anything moving crunching or running. If you hear any of this then you have a failed window regulator. If not, meaning you hear nothing, then you hae a failed window motor. Neither of these have a manual override function so, actually both will physically prevent movement of the window.
