Quattro Coupe in dash heated seat button light replacement

After successfully finding the correct 2721 lights to replace the dash buttons lights, I replaced the dash defrost button, fog light button, etc light only to find that the heated seat switches in the dash were apparently more difficult to replace than all of the other dash button lights. If anyone has any instructions or knowledge on how to dissassemble the dash heated seat switches and replace its lights would be of much help.

Also, the gauges above the ashtray need their lights replaced as well, so again, any knowledge on how to remove the dash gauges in attempt to replace their lights would be great.

- thanks in advance
