tis a doddle mate.
if i can remember.
you need to remove the screws from behind the Square caps.....if tha makes sense.
remove the trim from arond the door lever, you dont need to remove the lever itself, but you can if you wish.
you have to fiddle out the elctric window switch panel, i think, from the front,pull rearwards then up.
then unplug it from the wiring loom.
pull the doorcard away from the door at the bottom and sides, be careful with this.
then lift the door card upwards..you will see the clips that the top of the door card was behind..check there isnt any attched to your door cards.
this is from memory, as i dont that year anymore.[]
