I have a 1985 V6 Fiero the car has been sitting a while. The Dome lights go on. However, the Horn and the Lighter do not work. Is this possibly a Fuse that could be the issue? I checked the Fuse and looks ok and the Dome light works. I thought the Horn, Dome Light, and Lighter work off of One Fuse is this correct?

Anyone thanks!

Check all the fuses....Fieros are wired weirdly and you get some weird reactions when a fuse blows. The symptoms will show up on other circuits for some reason

Horn, radio and radio all are 1 fuse - marked batt I think

BATT fuse, as Phil said.

Fieros are not wired any differently than any other GM product from the era, nothing weird about them at all.

Weird enough....I blew that same fuse. Lighter, and stereo stopped working (as you expect) ....dome light stopped work also...lights on front of stereo stayed on all the time(not expected)

My SE has the same problem. I ended up running a new wire directly from the battery (with a fuse holder) to the battery power for the radio. I've never been able to find the battery wire for the radio, the one that powers the memory.

You can run a wire from the fuse box for the main power for the radio so that it functions as it should on the accessory circuit. What looks like half a fuse holder is a blade terminal socket. Just plug a male blade terminal in where it says "RADIO" next a half-fuse socket.

At one point I had run a wire from the lighter socket to the memory power for the radio. That worked for about a week. Then it shorted out, blew the fuse, and never worked again.

Some people said the lighter socket itself is the culprit and should be replaced. I disconnected my wire from the socket thinking that was the problem, but it didn't help. Putting a new fuse in just wastes another fuse. The Ogre has a page related to this under ghost power or something like that.

It would be nice to know what's going on...

The radio has two sources of power, one from the battery for memory, the other is switched. Lose either one and it doesn't work.
