I got an '82 in April this year, with a few known problems that I am in the process of fixing. I discovered one night that none of the dash lights were working. Had the main (headlight) switch replaced, so now the speedo and tach light up, but the lights for the gages don't. The light in the AM/FM radio works and the light above the heater/AC controls works. All of the gages and the clock work fine.
Questions:
1. Are there light bulbs for the gages?
2. How many?
3. How can I check/replace them?
4. Could it be a bad ground problem?
5. How do I check?
6. Could the circuit board behind the gages be the problem?
7. How can I check?
8. There is a fuse for gages, but I assume that is OK if the gages are working. Is this valid?
9. Is there a different fuse for the gages lights?

Thanks for any help,
Dave

There are light bulbs for the gauges...about a half dozen. They're in twist sockets. Your fuse must be OK since the speedometer and tach light up...they're on the same fuse.

The easiest way to check things out is to remove the panel...not difficult. Your radio is on its own power supply and built-in light.

My bet is on your printed circuit or where it's connected behind the panel. The contacts are very flimsy and after enough time and vibration it loses connection. That's what happened to my '78 a few months ago. I changed the printed circuit and no more problems.

Even if it is the printed circuit or where the wiring harness connects, put all new bulbs in while you have the panel out...removing the panel isn't a big deal, but something you don't want to constantly do. It would be a good time to change to a quartz clock or convert your original clock to quartz movement.

Thanks. What did the circuit board run you? I assume you bought a new one.

The printed circuit runs about $125 and is generally available from any of the Corvette supply vendors. The new ones you buy are probably better quality than the original, they seem to be made of thicker material than the originals. They're not difficult to replace...once you have the panel out, it's pretty obvious how it's done once you see it.

I'll take the panel out and check the connection to the PC board.

Thanks for the help!
