You dont need to remove the dash. I think the first thing you need to remove the radio, you need that speical tool, like $4 at Wal-mart. I cant remember how many screws and such are back there, there are a few of them I know you need to disconnect the light dimmer some how to. The black panel thing should then come off and you should be able to replace the switch.
Hopefully someone else will chime in.
