last night i rolled my window down and when i went to roll it back up it wouldnt go back up. so i took off the door panel and checked it out and their is this long white cable with little ***** on it. its jammed in the motor. does anyone know where it goes. or if i need a new one where to get one. i checked local parts stores and they dont carry it. any other tips in changing out the motor would be helpful as well! thanks
