my cable snapped and wrapped itself around the motor
If the windows is free to move up and down it means that the cable has snapped
also be careful if you are going to fit them yourself you need to be quick not to let the cable unravel itself in the new regulator as it is under tension
This is what it looks like when you take off the like twenty bolts the black bit near the metal plate is where the window motor sticks out from the inside of the door
i got my regulators from eurocarparts that way you have warranty incase you mess it up like i did
