Check with a voltmeter that current actually reaches the horn connectors. If it does receive electricity, then the horn has blown..(no pun). If it doesn't receive electricity then the cable has been severed somewhere between the fuse and the horn.

SOURCE: horn just went out

sounds like you have a bad horn or a wire has come off the horns can you feel the relay click when you press the horn inside the car? 

the horns (two) on cars are usually located forward of the radiator and behind the grill.  Sometimes they are better reached from below the car.  And usually you need to remove some plastic shield to get to them.  The fuse is in the fuse box and should be marked as is the horn relay.

When you receive advice from this website you have to understand that without the item in front of us, we are only able to provide "a best guess" as to what the problem might be based on you description of the defect.  If you haven't described a clear and precise description of the defect you decrease the chances of an accurate reply.  Thank you.

SOURCE: The Horn

This sounds like it could be damaged wiring in the steering column. Would suggest a qualified repai shop, especially if the vehicle is equipped with an airbag.

SOURCE: I have a 2003 ford mustang with no working horn.

The horn relay is inside a fuse box under the hood (drivers side). There should be 5 relays. The horn will probably be mounted near the frame (under the engine).

SOURCE: WHERE IS THE HORN FUSE ON 2003 OLS ALERO

There are 3 fuse boxes on an '03 Alero. The block with the horn fuse is under the hood. If you're at the front of the grill looking under the hood, the fuse box is on the drivers side closer to the windshield. It is rectangular (about 6" by 8") and has a fuse symbol with a little lightning bolt on it. The star knob is the only thing that holds the cover on.
The horn fuse on mine is #21, a larger gray 4 prong fuse. Good Luck with that one.

Horn has stopped working on my 2006 Ford Explorer. The fuse seems to be fine. What could be the problem?


I would suspect an underhood fuse, the steering wheel clock spring, or a wiring problem. It's cheap to triple check all the fuses. The other two will require some troubleshooting to figure out. Since the horn works with the keyless entry, the relay, the horn, and its control wiring seem to be ok.

Horn aux outlet cruise dont work


the horn and aux outlet use the same power circuit, I bet if you actually take the fuse out and replace it with a good one it will work.

I am assuming that you just looked at the fuses, sometimes a bad fuse will look good, but transffer no current.

Horn in 1990 Cadillac Seville doesnt work


If you hear the relay clicking,and even faint horn, check the connections on the horns themselves, there are probably two. If they seem okay then take a piece of wire and jump from +power to the horn terminal. Be prepared because if it works it will be very loud, and I know more than one person who's hit his head on the hood doing this. If it doesn't work, replace the horns. Hope this helps. Cheers.
