NEED HELP! I keep on blowing the same fuse!
It started a couple days ago, on the freeway, all of a sudden my stereo just losses power. It was to late to start to work on it so today I put a new fuse in and it blew again, I tried this two or three times.
The fuse blows right when I turn the ingnition to the "on" position. It's the #1 fuse that keeps on blowing which powers the radio, cigar lighter, rear defroster, glove box light, folder rear headrests, and the rear compartment.
I think that maybe some wires somehow got crossed behind the radio but don't want to pull it out if I don't have to. It is an aftermarket unit that I installed myself around 2 years ago. I'm just wondering if anything else related to this fuse would do the same thing.
UPDATE: I took out the stereo and capped all the power wires dealing with the stereo and the fuse still blows, so I doubt that it has to deal with the stereo but I have no other place to look. Everything else dealing with that fuse has not been touched and I don't see how those other devices would blow it anyway. I really don't know what it could be, I was fairly sure it was the stereo but now I can't say for sure. I want to get this fixed before I drive to Vegas or I'll go crazy!

You might be able to find it with an ohmmeter if the fuse is out of the circuit by going to each unit and testing.

Yes, no answer.
In this issue and my more recent headlight issue it just comes down to electrical gremlins. To solve this issue I cut the wire that was burning up causing the fuse to blow, don't really know why it was behaving like it did or what it went to, but 60k miles later it hasn't appeared again.
