Is that a yellow light that is located behind the vents under the dash pad? I have my interior stripped right now as I fix previous owners wiring splices, etc and I can accross it. It is a 1" square peice inset to the underside of the dash and has what looks like a yellow light in it. It has 2 wires going to it in a factory harness. Can't locate it in my GM service manual. What is it? What does it do?

possibly one of the lights for the HVAC control or counsel, if it is small that is.

I've also seen that called an ash try light, since that is the area where it projects.

That is it pulled out.

its a light but on most they dont give off any good anount of light. they have em there cuz its not a well lit aera on the camaro . just put an led in there

I recently put a blue LED in it and put it on a separate switch with some LED's I mounted in the heater vents...

Theres more mystery and drama around that bizarre light than anything else on these cars!

All we have is speculation about what it's for. COncensus seems to be that it lights up the HVAC/radio area.... but it doesn't do a very good job of it.

I sure found it mysterious. Guess it comes on with the dash lights then? Hmm, will have to keep an eye on it when I get these wires all sorted out.

It's meant to illuminate the console at night. It's meant to be only bright enough to help your eyes easily find the locations of the ashtray and shifter, etc, without being to bright to be irritating at night.
That's correct, it does come on with the gauge/dash. It's a gentle light, but if you think it should be brighter, check to see if it even works. If it does, the bulb hole may be filled with dust/dirt.

'89 was the first year for that light.

Cool!
That I did not know.

pre 89 had a different sytle then cuz i have an 87 and i have a different stlye one

It must have been added because the only pre-'89 I've had with a light there was an '86 Z28- and it had the dash from an '89 put in it.

my 87 has this light too...

It appears as though what models and years, exactly, had this light is still up in the air.

I need to get one of those. . .lol mine is missing. I feel like I'm missing out. I only noticed it after I bought my car. While cleaning it I felt a big azz hole under the dash and wondered what it was for. . .

My 85 doesnt have it and my friends 88 does not have it.

My 87 GTA and the 89 GTA I stripped for parts, both have the same kind. About 2" long, 1" wide, and rounded ends.
