Hey guys, doing the same to my 02 silverado...wish I had seen this post before(signed up today), I ran out to radioshack and picked up some 272-1141, 12v 25ma bulbs and soldered them into my hvac. Seems to work well but I noticed someone had better luck with a similar type but 6v, I'd like to know how that worked out...are they still lit, functioning properly? Guess I'll see how these perform tonight!

Add another one against the 12v 50ma radio shack bulbs. I got them to replace my burnt ones in a Sierra 2001 hvac control switches. They do work, but they are only about 1/2 the brightness of the original bulbs.
I wish I had read this before fixing mine. Now, I will have to get the 6v 25ma bulbs and re-solder them.
You must be correct about the "series" circuit voltage thing. Because when I put in just 1 replacement 12v bulb, it was the right brightness. But when I replaced all 4 of the top ones for behind the dial switches, they are only 1/2 brightness.
I only had 2 burnt out, but figured I might as well replace all 4 of them since I was doing it. My bottom bulbs for the a/c and defroster buttons, were fine, so I left them alone.
NOTE: I just found these replacement bulbs listed for sale on LMC.com website on page 141, if anyone else wants to look for them.
I'm glad I found silveradosierra.com, it's great to be on a site that actually has good information for a change!

Old thread revived...but good to see new members using the information. Although, it appears as one never came back after January 2012..

But welcome PickupMen...head over to the Member Intro forum and say hi, post some truck pics.

And if anyone else is wanting to do this, you can get the bulbs at Radio Shack, part #272-1141, at $1.99 each. I think you would need 4-6 to do all the HVAC lights.
