    Get one of those little 12v test lights. You know the thing that looks like a screwdriver with a point on it and a little clip on the end of a wire sticking out of the handle. Take the wire off the horn and stick it on the point of your test light. Then put the clip to a bare metal part of the car. Get someone to press the horn button. If the light comes on then the problem is with your horn. Get a jumper wire and put 12v straight from your battery to the + on the horn. (make sure the body of the horn is still touching the body of the car) If the horn does not sound then the problem is with the horn. If neither of these tests work then either you are not doing it right or both your horn and wiring are broken :) Hope this helps

    Do you have power to the horn when you use a test light and push the horn button?

I just wired a new horn on my 97 Nissan and it won't work. I had wired the same horn weeks prior and it only worked for a week. The relay and fuse are good. Should I check the sterring wheel?


Make sure all your connections are good. If the horn relay clicks when you push the horn, you're getting power to it but you might not be getting power out. Get a test light and make sure you have juice at the relay going to the horn and at the horn connections.

My horn does not work on my Kia Sedona 2005. Fuses are all good. Any help out here in cyber world???


lol, yeah, I'm here in cyber world.

Did you check for voltage at the horn fuse? Even if the fuse is good, if no voltage the circuit is still dead. From the fuse, the voltage goes to horn relay. the horn relay has two sides, a load side, line with arrow head, it shows open in the diagram, when relay is energized, that line with the arrow head moves to the other terminal and carries voltage to horn.

The control side of relay looks like a coiled up line, that needs voltage and ground to energize the relay. One of the grounds for the control side of relay is the horn switch on the steering wheel.

It may be possible to use jumper wire across load side of relay, between the proper two terminals and the horn may sound. If so, I think the problem is the wiring in the steering column.

Why isn't the horn working?


What is year--make--model? Check applicable fuses, check wiring circuit in steering column. Have to disarm air bag where applicable, before fooling with steering column.

The relay circuits need voltage and ground, w/o more info I can't look up the wiring diagram.

2000 VW Jetta TDI my Horn just stopped! I don't know which relay to start by, The fuse is good but no V at horns Is there a wiring diagram to be had?


There is a "clockspring" wiring spiral in the steering wheel to accommodate the rotating steering wheel with controls on it. If this breaks, you may lose some or all functions controlled by stuff on the s-wheel.

2003 dodge caravan airbag good horn doesnt work,so i jumped horn relay horn worked .so i now know relay to horn is good clock spring wiring horn pad?fuse compartment on wiring diagram has horn relay 20 amp...


if you check the wire that comes from the horn button to the relay for voltage when the horn is pushed and have voltage then you have a bad relay,if not then you probably have bad contacts in the horn pad area or even the clock spring itself.

2001 chevy astro van horn does not work already replaced 20amp fuse any suggestion.


really need more information. does your air bag light stay on, if so your clockspring below the steering wheel could be bad. disconnected the wires at your horn and with a test light see if the light comes on at the wire while someone presses the horn. if it does the horns are bad. there should be a horn relay under the hood for the horn. it could be bad. i hope this helps.

1986 Chevy Caprice Classic Horn not working


Diagram should be on the inside of the fuse box or relay cluster lid/cover. If Test light has 1 wire and a sharp tip? Yes, but only if you push the horn button too ;-)

My guess is that the horn lost its ground, but you can check this with the light. The horn only beeps when both GROUND and Pos 12v are present. The horn button gives the relay 12v to close, and the relay gives the horn 12v to operate. The ground is always connected.

Connect tester clipwire to 12v source (battery, headlight (has to be on) and touch its tip to metal of car. Does it light? Good. the tester is working and the 12v is a good source.

Touch one of the 2 horn connection or wires (poke it thru the plastic - why tip is sharp). Does it light? Touch the other, does it?

If both light, (1 will be brighter) we can assume the horn coil is good and it is getting a good ground and I was wrong (it happens... but not often). The side that is BRIGHTER is the ground wire side.

Now have someone mash the horn button. Do you hear a tiny click? That is the horn relay. If not, look for the horn relay fuse and replace it. If you DID hear the click, the relay coil is good and is trying to switch 12v to drive the horn.

Now is time to locate and replace the horn fuse or the relay may have bad contacts. Look at the other relay part numbers in the cluster and see if there is a match for the horn one. Swap it out and try the horn.

Hope this all helps. To 'test' the horn, touch the dim side again anf listen for a scratching sound. That is the 12v going thru the tiny bulb in the tester (a resistance) and trying to drive the horn.

Good Luck!
