OK, There's one screw on the inside of the grab-handle, remove that and pop-off the plastic cover (lower part).
There are now two screws exposed, remove those, and then there is one at each end of the door just under the line of the window, remove those.
Lift the door card upwards and then outwards (only a few inches at first, so you can get access to the bowden cable to the interior door-handle and unhook-it allowing more movement).
Job done.
Regards,
Rob.
