Hello, the vehicle's dashboard light is not coming on with the head light on. The radio too has refused to power. I have checked all the fuses they are in good condition. What could have been the cause?

Hi,

Has anyone else driven it lately? As far as the dash lights, have you checked the dash dimmer switch (if you have one)? Someone may have moved it.
As far as the fuses go, did you check both the under hood and under dash boxes with a test light or volt meter? Is anything else not working?
I know I'm hitting you with questions, but I see no immediate commonality with the two systems. A common item in many vehicles is the cigarette lighter/power outlet circuit that is also involved with other electrical systems. Please see if it is working.
Other techs may jump in if they have other info or have come across this before.

Yes, I checked the both the under hood and under dash with test light. Could I have a circuit diagram for this?

Hi,

I noticed it's been a couple of days since you were here. As far as the wiring schematics, I attached them below. I cut it in half to make it readable.

Let me know if that is what you needed. It is for the instrument panel/lights.

Let me know.
