Ok, ever since a penny fell into my lighter, just about all of my interior electronics haven't been working. Basically, the dome light, power locks, light in the center console, lighter, and the light above the radio aren't working any more. I've checked all the fuses and it's not that. I'm guessing it's something nasty down inside that's burnt out. Anybody know what it is or how I could determine what shorted out using a multimeter? I have removed the penny, btw.

 

Everything that powers what you posted is through the accessory fuse. It should have blown when the penny shorted (I'm guessing) this circuit to ground.

I know you said that you "...checked all the fuses and it's not that...", but I can't help but think that it's still the fuse. Even if it looks good, is it possible that it's not making good contact, or "blew" and you cannot tell by just looking at it?

 

Har, that was it.. Good call, man. Thanks.
