No dash lights. Fuse box?

None of my instrument panel lights worked. I looked at the bulbs first and saw that they were still good. Ended up being an old rusty light switch dimmer. Turned the dimmer back and forth many times to get some of that surface rust off and all of the panel lights worked. Might be something to try if you have an old switch like me.
For the headlights? I'll try that out
