Let's start with the A/C knob, circled in the second pic. It pulls straight off. The bulb is then visible. But don't replace it yet.

When you get the knob off, you'll see the big brass nut underneath. Remove that. Carefully pry out all of the accessory switches in that upper panel. When you do, you'll find that each has a fiberoptic cable in addition to the the wiring.

With all the switches out, you can now remove that whole panel. Pry very carefully because it is easy to crack. Once out, you'll see the bulb that attaches to the back side of it.

The heater control panel has a similar arrangement, with two bulbs mounted on the back and one in the middle of each knob. Be sure to get the right size bulbs for these, as it's easy to make a mistake and get the next brighter ones which will be too hot.

Now for the fiber-optic lighted switches, you have to replace the bulb at the center of the "octopus." Follow those lines until you find it down inside the dash. I found that easiest to do when the radio was removed.
