sounds like one of the cables has snapped, the noise you hear is the loose cable rubbing on the moving winder drum, it's a fiddly job to replace these cables a kit is around £40 from UK. Are there any good scrap yards over there? just rip off the door card & plastic sheet, make sure you've got a goodun, un-plug elec. connections & undo the 10mm bolts that hold the motor & frame inside the door, un-clip the glass (position glass nearly at bottom is better) & wedge it out of way, remove complete.
