Here is a guide to dismantling the door panel or dismantling it.
On the front doors there are 5 screws
There are 4 screws on the rear doors.
Two screws are at the bottom of the door panel on the front doors and one screw on the rear doors
A screw is behind the aperture in the door opener shell. To remove the cladding, press easily on the right side inwards and the aperture should rise
Two screws are in the door holding handle
Once these screws have been removed, the cladding is only held by plastic clips. Simply pull a little more jerky at the bottom of the fairing so that it loosens and then the cladding can be hung out on top
