Hello Simon,
If the 3 Torx screws are removed then it assists the actual armrest to be moved just enough to allow a much easier removal of the switch surround.
I followed this procedure last weekend prior to painting some leather armrests. You can get to the surround tabs through the aperture in the door card that the loom follows. Even with fat fingers (like myself) the surround should be out in seconds.
@a2lover, if you want to see how easy a task it should be then I’m more than happy to supply my phone number over PM to talk you though it over a video call. I have a spare door card here to use for a demonstration and talk you through the process that avoids any damage to the tabs or the armrest covering.
Kind regards,
Tom
