UPDATE: HVAC light bulb replacement...
I went to Radio Shack and bought a bulb (Part #: 272-1154) and proceeded to pull apart the car and remove the HVAC control module. Everything came right out and the control module opened up with just the 4 screws on the back. I found that I was able to work without separating any of the wiring between the boards or removing the ***** from the faceplate. A little heat from the soldering iron and the stock bulb pulled right out of the board. Again the soldering iron was applied, this time from the front, and I was able to push the new bulb right through the board. A little flux and some heat and the bulb was soldered in. There was plenty of solder on the board still to not need any more. I cut the leads with a small pair of nippers and assembled everything and the bulb lit up. I will be ordering some more so that I can replace all the bulbs as I noticed a few more were out. It is a relatively easy thing to do, and I would say anyone with a little experience with a soldering iron should be able to do this and save themselves some money.

HVAC Display
Chris congrats on your fix. I have a 99 and my HVAC display has gone out (won't illuminate). Over time it gradually disappeared, I just posted a question about this. I asked the GM parts guy and was told I needed to replace the unit itself (part cost approx. $400). If you don't mind would you give me any and all particulars (cost and which bulb from radio shack) for this fix.
Thanks

It is plug 'n' play and takes about 45 minutes to replace. There are places that will repair them, but I didn't want three weeks downtime while it happened.

The bulbs and LEDs only light up the buttons and blue and red around the temperature *****. The display is it's own separate unit, and I do not believe it is backlit, but rather generates its own light.

Here is a picture I took of the board after the new bulb was soldered on. Sorry the picture is so blurry, but my camera does not like focusing that close. I will try holding a macro lens in front of it next time I have it apart. The new bulb is the one with the white base 2nd up from the bottom.
