Default C6Z no instrument dash lights or high beams

I have no dash lights when my head lights are on. My dash lights only work when my head lights are off. The control for lighting and dimming the dash lights does not work when my head lights are off and my dash lights are working. another issue is I have no high beam only low beam. Any ideas on how to solve this issue would be greatly appreciated. I could not find a fuse that was associated with any of the issues. Thanks Mike

The first thing I suggest when there's any electrical glitches with these cars is to disconnect the battery for a little bit, then reconnect it, and while your at it clean your battery posts. Often times this will reset things and get them working properly again.

The only idea to solve your problem is to take your car to an automotive electrical repair shop...this is something we can't solve over the internet as their are too many variables and if you have no electrical diagnostic experience so much the better.

Likely not your issue, but a failing multi-function turn signal switch can cause all kinds of crazy lighting issues.
