Brand new to the the forums. Heres the issue. When I start the car the dash lights look fine. When I turn on the headlights the dash lights go out. They work fine during daylight hours. Any suggestions??
When you turn on the lights - the instrument lights are supposed to
get dimmer. Sounds like a switch or connector problem.
Does this also happen when you just turn on the parking lights ?
See if anything different occurs when you have the fog lights on (before turning the light switch).
Was this working OK before ?
Also - do you have a Factory shop manual ? If not, get one. It will save you a great deal of cash in troubleshooting you own problems over time.
Thanks to all you Vette loves out there. The dash lights work just fine during the day. i first noticed the problem when I lleft for work at 5 AM. No dash lights when I turned the headlights on. Later, when I got off work I had lights so I turned on the headlights and to my surprize the dash stayed lit. So thats it in a nut shell. I'll try your solutions and get back with yoy folks later. Again thanks for the help. Keep cruzin y'all.
I thought I had this problem, then found my dimmer switch turned down. <<As VigMan states.
The light sensor adjusts the dash brightness for ambient light, as I found during daytime tunnel entry with sunglasses still on. For testing, my finger did not shield enough light to trigger (darken) it, but dark tape did. Mine works fine when operated properly. LOL
