I've been meaning to post a how-to but I been short on free time. I don't have any process pics but I can describe what I did. I ordered the 3mm blue LED's from e-bay I think a set of 10 for about $2 and if you "buy it now" he throws in 10 resistors for a 12v system.
I soldered a resistor to the LED then used heat shrink on one lead so they won't short. Basically it involves a lot of trial and error just to get the right fitment. I could only replace the main bulbs in the two outside buttons, not the small on/off lights at the top of the buttons. You just wire the LED's and resistors the same way the bulbs were wired with the leads through the little "hats". The on/off light in the a/c button on the left is a LED but I couldn't open it up to change it. And the on/off light in the right defroster button is a small bulb but there wasn't room to wire in another LED.
For the center button for those who have it (the fresh/recirc button) there are two small LED's that can be replaced. These are easy to replace, just solder two new LED's to the board.
Remember LED's do have a positive and negative so you might have to test it a couple of times. The resistor also has to be wired on the right lead you can test it on a 9v battery to be sure.
