Fuse box question

Why do you want to remove that panel? You can access the fuses with it in place.
There are 3 or 4 blind clips retaining the end of the panel closest to you. I usually wrap a big screwdriver with duct tape and pry gently at the seam between the panel and the dash to get it started. Pull the top edge of the panel in a direction perpendicular to the steering column.
There is a sheet metal cover directly behind the plastic one. It is retained by 2 more bolts.
