Electrical Need Help With Dome Lights

[Ty B]

Hey everyone I made this account because I need some help with my lighting. I don't know what happened but my dome light, map light, and stereo all stopped working AND IT'S NOT THE FUSE! I've checked that already. I believe it's the power circuit but I don't know how to replace the wire. Any help is appreciated

@Ty B

It sounds like you have broken a ground behind the dash. Have you done work back there recently?

Do you have and know how to use a volt meter? I can help trouble shoot if you do.
