Yep ! Jack is right on this one.
Actually not too hard to remove.
FIrdt you will need to remove the door trim.
To do this, you will need to remove the arm rest, the Door Handle, and the Door Lock Button, as well as the plastic bit that covers the mirror screws.
Once all these have been taken off, to remove the door trim, simply pull it upwards, to disengage it from the door, near the glass.
Once you get to this stage, you will notice that there are 3 big Rivets, that hold the regulator assy in place.
To remove this assembly completely, you will also need to remove the Window Guide, to disengage the regulator from the Window.
Finally, if you need to do this, you can unbolt the window from the guide, as it is held in by one bolt.
