There's alittle cap in the grab handle, pop that off with a screwdriver and there's a screw underneith.
Undo the screw and the grab handle will pull out giving you access to the window/mirrors switch.
They just unclip/push out, took two seconds to replace a previously glued in one on mine.
Take them out, rub 'em down, repaint, done.
I got mine looking mint on my old car. I could try to supply you with pics, but they're in a thread from a long time ago, and I'm lazy.
