Surprisingly the manufacture date on the new one was from 2010, so I'm hoping they've put better bulbs in this one. Finger crossed.

Is it safe to say that you can?t pop the covers off and replace the bulbs back with normal bulbs?
Thanks,

Re: Instrumentation Illumination Question
Nope...those little, fragile bulbs are soldered in place.

Greaaat... damn GM. Guess I?ll pull the panel out and send it out. There?s a company we use that does all sorts of repair work to instrument panels, speedometers, radios, etc, etc...
Just out of curiousity, how much was your replacement unit?
New or used?
Thanks,
Mark

Re: Instrumentation Illumination Question
I went with a new one...I think it was just under $200. So far, so good, all buttons still lit.

Re: Instrumentation Illumination Question
Thanks bud, I appreciate it. For under 200 bucks, it?s not worth me taking it out and getting it repaired. I?ll have more in it than that repairing it and shipping.... not to mention downtime.
Thanks,
Mark

Re: Instrumentation Illumination Question
I know this is an older post and apologize for bringing it up again, but I was just wondering where you all bought your new AC controls at? In an earlier post tonight, I mentioned that I am working on replacing several items in my dash due to bulb issues, and this is one of the items needing replacement. I looked on gmpartsdirect, and they wanted something like $270. Eventually, I will have to replace my guage cluster too (a bulb is out behind the speedo and I have recently lost my PRND321 lighting as well...it is there but just extremely dim). Thanks!

A few things...
I think (it?s been a while since I pulled mine apart) the PRND321 has regular light bulbs behind it, I can?t remember if they?re LED?s or not. Perhaps someone one here can verify.
The lights on the speedometer can be repaired by someone that works on them.
When I put the diesel in my mine, I needed to replace the gauge cluster with one out of an HD2500. He was able to reprogram, change and fix things I didn?t know you could do on a gauge cluster. (I found him on ebay)
The buttons on the steering wheel can be replaced by popping them out. (I know you didn?t mention it but I?m on a roll...lol)
And last but not least, you may as well suck up the 270 bucks. I was unable to find anything else... not saying it?s not out there, just for the brief amount of time I looked, I didn?t find anything.
Good luck.
Mark
