Climate Control Panel Lights

I was driving tonight and noticed my Climate control panel wasn't lit up. The little lights on the end of the slider knobs worked, but not the panel itself. Anyone ever pulled the panel out to replace the bulbs? If so....does it pop out, or are there hidden screw somewhere?
Also.....does anyone know which toggle switch buttons are suppose to light up? I know the rear defrost one does, along with the cruise cont. one.....but what about the rear wiper, mirror control, dimmer, and voice control switches?

Just pull off the slider knobs and pop the cover off the cover. There are no hidden screws. Then you will see the screws to remove the unit. I think there is just one bulb maby two.

Hey great.....thanks for the info. I'll tear into it tomorrow

they usually are 194 bulbs in the dash.

Thanks for the help everyone. Replaced it today.....popped the knobs off the sliders, then popped out the face, and popped out the clear diffuser lense to expose the single bulb. It wasn't a 194 size bulb though.....same "wedge" design, but about half the size of a 194.....not sure of the number, but I had a spare bulb left over from the 2 pack I bought a few years ago when I replaced the ash tray bulb.
