Okay so my 1981 FJ40 interior lights aren't working, not an issue as long as I drive during daylight hours. I can't see the instrument panel to guess how fast my flying brick is going when driving. Here in Alaska in the winter, kinda need to see that stuff. Oh and the radio isn't working either. Replaced the radio fuse, no joy. Any ideas where to start would be great. I have all the factory manuals, so I don't need schematics, just ideas.
