Easy as pie.
Remove door card by removing the inner door handle (it separates) then undo the two screws behind it.
Remove door pin and then pop the door card off (feels like its going to break). Remove plugs for window switch and speaker.
Peel back the lining and put the window down till you can see the two bolts that hold the window.
Undo them and remove any old broke glass, slide new glass down (at a angle).
Just make sure you line the glass up before tightening everything up
