Wow that's a job replacing them and once you have the switches removed how do they separate from the switch?Bezels are held on by the switch. In other words, the switches need to be removed in order to replace the bezels. Probably easiest (for me anyway)to remove the gauge pod to gain access to the backside of the switches.
Cig lighter just has a threaded sleeve on the back to unscrew.
Light switch knob is removed (pulled out) after depressing a button on the side of the switch. You'll see the button with the gauge pod removed.
Ignition switch, take a straightened paper clip and insert in the small hole then turn the lock assembly (with key) ...I forget which way ? I think counterclockwise.
I forget the wiper knob too, I'm pretty sure it has a set screw ? Then nut can be removed.
So this tool only takes the bezel off for the ignition switch only or will it work for others as well?Ignition switch nut uses this tool a "Camaro Ignition Switch Bezel Retaining Nut Installation Tool." But you also have to do the paper clip trick, if you internet search that you can find more details.
