I have a 95 Buick skylark custom 4 cylinder. I've been having horn problems for a while. Not that it'* a big deal, but I'm interested in knowing if I can fix it before I rig up a fix. So when I bought the car it wouldn't shut off unless you unplug the fuse. So I went to a junk yard a bought a center airbag/horn switch. Well of coarse the horns were bad as well so I got new ones, as well as a new relay. still nothing, recently my headlight switch stopped working so I replaced that.
Any ideas? I'm thinking a bad wire but where? Is this common?

You need a schematic.....need to find the wire coming down the steering column that grounds your horn relay......then ground that wire(can back probe it in the harness).....if the horn blows, the problem is in the steering column....sometimes the ground under air bag comes loose.....could be a bad connection at the multifunction switch or cancel cam ......this involves removal of steering wheel.....if you have no experience with air bags, leave it to the pros....

If the horn doesn't blow when you back probe the harness coming down the column, then check the relay circuit....

Well the ground for the horn is just a wire that plugs into a screw hole and that'* fine I've tried running a separate wire from battery to ground wire on the horn button. I was thinking about running a wire to skip the column. If that makes it work I could run a new power wire for the column. If it doesn't then it means either the power wire has a break or the ground is bad on the outside of car. Would this work? I plan on using homemade jumper wires essentially to test the wires. If it'* the outside is the problem I'll just use a jumper wire to run a new ground on the outside. Vice versa if it'* the power

sounds like a good plan
