Did this at the weekend.
1) Remove the threshold trim that runs along the door sill.
2) This will expose one crosshead screw - remove it.
3) Then just pull the cover outwards and towards the rear of the car - there are two pins that hold it in place (one near the speaker 4o'clock, the other near the top of the panel.
I foud it easier to also remove the bar along the underside of the glovebox (2 visible screws). I was then able to pull back the carpet and I could see all manner of fuese and wiring!
