Gauge Lights Out

spradling · June 21, 2004

The panel gauge lights (speed lights, AC lights, stereo lights) turn off when I turn my headlights on. When the headlights are off, the gauge lights are illuminated. Strange problem. The "ELC PWR" warning light is also visible. Any thoughts?

Are you sure that the "brightness dial" is turned to the right? If it is turned too far to the left, they will go out when the lights are turned on.

agreed

I was just wondering- did you check this?

I also agree . . .

Here is why . . . if you have your brightness dial all the way to the left and your headlights are on, it turns the instrument cluster lights off. If you shut your lights off, the instrument cluster will light up. This is because it is assuming that you are driving in the daytime, and it is more difficult to see the cluster in the sunlight, so it lights it up automatically. I think this is the reason?

Anyways, let us know if it worked.

Thats what I think. If it is turned to the left all the way- it "thinks" he/she wants his dash lights off. Hopefully he/she is not trying to repair them, because it seems like it may simply be switched off.
