In order to do the doors, you have to peel back a small amount of the weatherstripping on the other side of the door and there will be a small hole there. You will have to use a 1/4" drive socket, a 7mm if I remember correctly, and remove that small plastic nut. Be careful not to drop it down in the door or lose it, easily done. Then after that, unclip the top part of the paneling from the rear to front, but it will be hung on the very end. Then unclip the bottom from front to rear, and it will also be hung at the end. Then, shift the paneling to the rear to unhook it, and then back to the front. Just one thing, the paneling is very difficult to unclip, the plastic clips are very hard. Don't get too wild on it, b/c then you might bend the metal trim piece. Also, don't use a metal pry device, b/c you might scratch the paint. It's a very delicate procedure. Some sort of a plastic pry device would probably work the best. For the corner pieces, they just come off. Just give a firm tug from the bottom. Oh, and I disagree with donbryce, the clips are for the most part sacrificial. Some will come out ok, but most will break. And they are expensive once you add them up. Hope this helps. Sorry, no experience with the sunroof.
