I just bought an 02 Z06 and I drove it at night for the first time last night and all interior dash and panel lights work as expected when the low beams are on, but when I switch to High beams, the only lights on are the dash high beam indicator, radio clock display (not the buttons), and the temp control display (not the buttons).

Is this normal?

Not normal.

I just took a look at the wiring diagram

After the turn signal switch the high beam circuit has a tap off to the instrument panel lights circuit which grounds out at G201. This may explain the weird interaction.

I'd try two things. Try some electronics cleaner into the headlight turn switch stalk. They are notoriously unreliable and a good clean often fixes various snags. Also you can try to clean up the ground (G201).

Thank you very much for looking into that for me DeeGee!

If that doesn't work there are a few more things that guys have tried to fix it with but yours is an unusual one.

I agree with DeeGee to. You might look at G102 at the front right frame rail. I think the headlamp controller grounds go through it.
