    Most definitely! That year I think the horn, interior lights and cigarette lighter are on same curcuit.

    It's a 20 amp fuse labelled Horn/DM if I'm not mistaken. I blow that fuse all the time because I have a short or something with a cig lighter. every few times that I go to plug my radar detector into it, it blows the fuse, then the cig lighter acts weird. When the overhead lights should be on, the cig lighter has no power, but as soon as the overhead lights are supposed to go out, the lighter comes back on. Weird quirk that I haven't gotten around to resolving with a new cig lighter socket and a relay to pull from the battery directly or something like that.
