The local dealer said the bulbs that light the climate control buttons at night are not sold separatley, the whole panel must be replaced. I went to radio shack and found a bulb part# 272-1154. It is 12 volt 50mA. After soldering it in I can say that it works fine. Hope this info helps someone else.

Kinda like the stereo bulbs.

Most of the time they consider items like that "non serviceable." Hence why they wanted you to buy the whole console. Most anything light powered can be replaced.

Same thing the local dealer in my town said to me when I needed some door panel clips "we dont have the clips, but we will sell you a new $400 door panel", and then I made the mistake of going to the dealer to ask for DIC bulbs, "we don't carry those but we will sell you a new DIC", although they did call a local NAPA store that carried the bulbs for me. MAn, I used to be able to buy GM hinge bushings from this same dealership years ago, I guess they just need to tmake MORE money, and not piddly wiht the little things.

I did some digging in my photobucket album, I had to replace almost every bulb in my digital HVAC control. Radio Shack had what I needed, several house later with steady hands...I got it done. Everything worked, and still works, so it was worth the effort.

GR8, I did this on a friend's dispaly over the weekend and shortly after starting to de-solder the bulbs, we noticed the same dark (burn) spot under the glass display, as seen in the lower right of your display on your photo here. Any ideas what caused this? We are pretty sure it wasn't there before we started.Originally Posted by GR8racingfool

Yeah, I replaced my HVAC bulbs and fog light switch bulbs with LED's.

this thread will come in very useful for my future endeavors

Are they the same bulbs for the heated seat switch?

SnowDrift, if you are asking about the bulbs that backlight the seat heater buttons, I think you can use the same bulbs. Maybe somebody else will chime in.

The illumination light appears to be the same, but the bulbs for the hi and lo are much smaller. There's a Radio Shack in a town I have to go to tonight and I might just stop off there to look at their selection.

GR8, what's the black spot in the lower right corner of your display screen on your HVAC controller? Did something cause a short when replacing your bulbs?

97 and 98 DICs used the green
99 and 00 used red factory.
I also believe the button placement was different

Found this existing thread... Thanks to the OP. Yes that helps. I currently have to do a fix. I've seen these bulbs on a video, and the brightness looked the same, but the physical size looked smaller (like the smaller ones in the radio). - Any recollection on that?
Extended post:
I want the lighting to remain consistent, and that is why I am being so picky. Now that Radio Shack is gone, these are not as easily available (and leftovers may only exist on E-bay). As I have found, these are specified as Radio Shack; 12V, 0.050A, bi-pin; P/n 2721154 replacement; 4.5 mm(?).
I have also found Eiko's 40910-7371-Miniature-Automotive-Light-Bulb/176064795; 0.48 watt - 0.04 amp - 12 volt - T1.75 - Bi-Pin (G3.17) Base | Eiko Incandescent Miniature ; Automotive Light Bulb; Average Lifetime: 10000 hours; Lumens (light output): 1.51 [halogen].
There is a difference of 0.01 amperes, but the Eikos are halogen, so the brightness might be equal. Bulbs are currently about $2 a piece.
I am not interested in LEDs (not going to get into replacing all of them and dealing with dimming problems due to LED dimming needing SMPS (switch-mode power supplies), PWM {pulse width modulation) and adding resistors to get to the right forward voltage (current).
FYI, I scavenged one out of a parts-radio, and the bulb was physically smaller. It's doing the job, but I'll have to do the job again since an additional other intermittent problem really isn't fixed. - A tap will get it lighting, and I think it may be a busted filament that just makes contact after tapping. I checked the circuit board, solder connections and resoldered the connections, but the problem remains.
Anyway, this is my knowledge and contribution on this, and any comments/experience is appreciated.

Sure you don't need 3mm grain of wheat bulbs? What part is broken, exactly?
01-04-2018
These are the incandescent bulbs (5?) in the HVAC controls cluster (no separate sides control, no automatic control). The grain-of-wheat bulbs look similar to what is there except without the seating collar. I was looking for if anyone knew what the original factory lights are and what their name is.
