Well, when I bought my car, this problem came with it. all of my fuses work and my car functions properly except for my *courtesy* fuse (horn, interior lights, door chime, power locks, etc...) When I put in a fuse, within 20 seconds it will blow, or as soon as I tap the horn it blows. I still do not know if my horn even works. So guys, the question is, how would I go about fixing this the most simple way possible?? I've been told it was a bad ground or a possible short in the system. If this is true, where can I find this ground or short and fix it??
