i was checking radioshack earlier, closest i could find were a couple 40mA LEDs:

The backlight bulbs all run in series off one circuit;
Radio Shack sells a 60ma bulb that is very close to the stock 70ma. I recommend replacing all of those at once...
The LEDs are controlled by the buttons each one represent but I'm not sure where that circuitry goes. If you have a few LEDs out try replacing them...
And that's all I know!

NO... not as a direct replacement. LEDs must be installed with an appropriate resistor before they can function in place of the stock bulbs.
The stock bulb is a 70mA incandescent bulb and can be purchased here;

There are some 60mA bulbs available also that are more readily available.

Somewhat... I've never dealt with SMT Caps that were black and marked "241". The ones I've known always seemed to be brownish in color and had no markings.

The soldering fix worked for me 
. No more dim readout! Anyone who is hesitant to do this fix themselves shouldn't be the process is straight forward. The only thing you'll need to have is patience, that and the tools of course. Thanks for the help!

broken resistor
d'oh!
so while resoldering these i slipped and broke one of the 241 surface mount resistors with my tweezers. anyone know where i can get a replacement? by any chance is there something i could score from radioshack that would do the trick? thanks!

Radio Shack sucks. There should be some type of electronics distributor near you, check local TV repair shops and they can let you know where they buy their transistors and stuff from. These types of stores make Radio Shack look like Walgreens.

no luck with radioshack. found a place online that has them:
http://www.westfloridacomponents.com...Store_Code=wfc
the 241 means its a 240 ohm resistor. (24 x 10^1)
woohoo! i learned something new.

Nobody who has the dim HVAC display defect in their car needs to endure it like I did. Like an idiot, for many months, I either tapped on the screen to brighten it a bit or I guessed at the settings. Now I consider myself kind of handy (I did the headlight gear fix myself) but I was really wary of soldering a circuit board in my C5. I finally got my butt in gear, removed the module and sent it to CF member tstar in PA. He's one of the trained pros on this forum with regards to lighting. My display was back within days and all I can say is it's great to have the HVAC control module shine like new again. He even replaced some burned out command button bulbs for me. I'm not saying that people shouldn't try it themselves if they are so inclined, but don't live with this defect any longer than you have to. If you're afraid of breaking something (like I was), there are forum members here that will save you big $$ and hook you up. From what I have heard, even if you purchased a new module from GM, the solders are lame on those units as well. <end of rant>
Thanks again Tim and Happy New Year everyone!

When my climate control head unit display went dim in early 2005, I didn't know about the simple fix on this forum, and had a GM dealer replace the unit. That was very costly up here!
And earlier this summer, that unit started going dim too, so the replacement units that GM is selling are just as bad if not worse than the original ones! You'd think they would learn and make them better but then don't care!
Eventually I'll get around to fixing it (definitely not in this brutally cold weather, I hate working on the car in the winter!), but mine hasn't gone completely dim yet and sometimes it'll go completely bright for a few weeks at a time, so it's not that much trouble for me yet.

following up on my earlier post about busting one of those surface mount resistors, i have quite a few extras of these now, so if anyone else screws up and needs one, feel free to PM me and I'll throw one your way.
thanks a ton to everyone thats contributed to this thread, this is terrific info!
