Last week I saw the green LED illumination in my HVAC display had gone very dim. With no obvious fix I did a search of CorvetteForum and found it's a known problem for C5. The fix involves dismantling the HVAC control unit and re-soldering a group of tiny components. Cutting a long story short I bit the bullet, worked through the fix and now the green HVAC display is back to the same brightness as the clock/radio.

The burn on my thumb stands as testament to my soldering skills!yikes

Details here for anyone who has the same problem, http://forums.corvetteforum.com/showt

My HVAC power supply board (1999) was the same as the image posted by EnglandGreen. It seems there was a design change but both layouts suffered the same inadequate soldering when manufactured. Thanks to CorvetteForum and the power of the internet for this fix.

Sounds like it's a very common problem then. Happily my DIY fix seems a good 'un!
