So the title pretty much says it all, can't get my brat's interior lighting to work besides the dome. Would very much like to have that, what are the main wires for that? Also, my heating doesn't work, but I don't have my ac compressor connected, don't know if that's the problem or not. Anything helps

Thanks

Check the fusuble links under the hood in the little black box by the battery cable. There should be 4 links, 1 black (main) and 2 green, and a red. see if one is broken or missing. A modern 'J-fuse' can be substituted as a replacement

Previous owner hacked the wiring harness so shreds. Ended up unplugging something and it worked.
