How to replace the horn fuse?


Most of the time it is not a fuse, it is the relay. Horns use alot of voltage to work , and therefore use a relay to close the circuit to make the horn blow. some relays are under the dash, some behind gloveboxes and a few in the engine compartment. You give no make or model of your vehicle so I have no Idea where it would be. You will need and electrical schematic of your make and model to locate the relay.

Horn does not work, horn buttons are good, horn contact in steering cololm is good, battery level is good, can't find a fuse in fuse box for horn.


if you take a test light and test all the fuses in the fuse box and if they are good then when pushing on the horn button you can usually hear the horn relay working(click).if it does then you need to check the horn itself.take a wire and run it from the battery positive cable and connect it to were the horn wire connects to the horn,it should blow(make sure of a good connection),if it does then it could be a dirty connection at the horn.if it doesn`t blow then the horn needs replacing.you can also use the test light and test for power at the horn wire at the horn itself to see if the horn is being feed power from the horn button to the horn.

Your problem is most likely a defective clockspring assembly. This is also called "spiral cable assembly" it is located just under the steering wheel on the steering column and makes the connection between the main wiring harness and the circuits for the air bag and the horn. I cannot give you wire colors because your question did not mention year, make, model, engine size or whether the vehicle is equipped with cruise control or not. (cruise control makes a difference in the clockspring assembly used on your car.)

Anyway, the air bag and steering wheel has to be removed to fix it.

My horn on my Buick Skylark will not work. It blows every horn fuse we replace. How can I get it to work?


You may have a short circuit in your horn button causing the
fuse to blow when you press the button or in the horn itself.

1. Locate the horn under the hood normally in the front of
the engine compartment.
2. Once you locate the horn, disconnect the wire from the
horn.
3. connect a VOM (Volt Ohm meter) to the horn's wire.
plus(+) side to the wire and negative (-) side to ground
or some metal part on the car.
4, set the VOM to dc voltage and have someone press the
horn button. You should read 12 volts on the VOM, if
not you have a short in the horn button, if you do mread 12 volts
you have a short in the horn. Replace the horn....

1995 LeSabre: Horn honking randomly. Is there a way to use the existing horn and run a wire to a separate switch to the inside of the car? The cost to replace the switch is too high since it located in...


You can by-pass the horn pad on the steering wheel and install an after-market Horn Button to operate the horn, and you can purchase an after-market Horn Button from most auto part stores for under five dollars, and there are a few different designs that you can choose from.

You will also need enough ground wire to wire the horn button into your vehicle, and most likely a few wire connectors, and that can all be figured out once you actually see the Horn Button that you purchase.

To install the Horn Button:

First locate the turn signal switch wire connector and it should be on the lower right side of the steering column.

Then locate the Horn wire, it will have battery voltage at the wire and when the horn wire is grounded the Horn will operate or sound, and usually GM used a Black wire with an Orange stripe for the Horn wire at the vehicle wire connector for the turn signal switch from the vehicle wire harness, and the wire usually changed to a solid Black wire on the wire connector from the turn signal switch. However that is not always the case, and the wires should be tested to be certain of the Horn wire.

You can connect a test wire to a good ground and quickly make contact with the wire that you are testing and when the Horn sounds then you have found the right wire. (make contact for only a second and do not ground the wires that you are testing for more than a second or you could blow a fuse)

Once you have successfully located the Horn wire, then on the wire connector from the turn signal switch, cut the horn wire about three inches from the wire connector for the turn signal switch. (or at least enough to connect a wire to the cut Horn wire from the turn signal wire connector)

The rest is simple, you just connect one of the wires from the Horn Button to the cut wire from the turn signal wire connector, and then connect the other wire from the Horn Button to a good ground, and then test the operation of the Horn Button, and if the horn is working with the new Horn Button then mount the Horn Button where you want it to be and the job is complete, and you should then have a fully functional horn again.

I have made you a wire diagram to help assist you, but it is only for a referencre and the wire colors might not match, so be sure that you actually test the wires to find the actual wire for the horn. Let me know if you require any further assisance.

On my 1972 duster,when i blow the horn,the fuse blows and the tail lights go out also. the same fuse runs both.what could be the problem?


This sounds like the horn may have a short in it somewhere. Does the horn blow at all? Try this: Make sure you have a good fuse installed to this circuit again. Disconnect the horn and place a volt/ohm meter set to DC volts on the horn connections. If there is just 1 wire going to the horn, put that wire on the red wire of the meter. Put the black wire of the meter to a good ground, preferably the negative battery terminal. Now press the horn and see if there is a reading of around 12 Volts. If so, replace the horn. If not, and the fuse blows again, check the wiring for a fray/short to ground. When you're looking at the horn of course, make sure the positive lead isn't shorting to ground as well.

I hope this helps! Let me know if you need any more assistance! :)

1988 Ford Crown Vic Horn Relay Location


The horn relay IS NOT located in a box toward the front of the engine. It is located just behind the radiator overflow reservoir and attached to the inner fender next to two other relays. It is the only one without a plastic cover over the top of it. FYI, our Crown Vic horn didn't blow, and the cruise didn't work. I changed the relay and still no horn. I decided to check the horns themselves. Found wires disconnected from terminals. Touched wire to horn terminal and horn blew incessantly. (previous owner had disconnected horn rather than diagnose why) Pulled the horn "button" from steering wheel and disconnected the wire leads and horn quit. Disassembled the "button" assembly. Foam had degraded over time between the contacts. (Ford has discontinued this part). Cleaned and replaced foam with Scotch foam mounting squares with holes punched out over contacts (2 layers thick). Re-assembled and viola! Horn and cruise control both work! Relay was bad as was horn button.

Horn doesn't work in my Mitsubishi Mighty Max Pickup


First could you do a couple of test to confirm what is actualy wrong?You will need to buy a test light/probe to confirm power to the horn etc,the tester is cheap and a good addition to any self diagnosis you do on the vehicle.Try running a wire from the horn positive terminal directly to the positive side of the battery to make sure the horn actualy works.Also make sure it is securely bolted to the car,not loose as its bolted down tight to give the horn the earth it needs to work.If horn doesnt work when directly connected to battery you will need to replace it and problem solved but if it does work then you will have to check the power to the horn button cant remember exactly but I think its the centre of the steering wheel.Make sure the wire coming through the centre has power.Let me know how you go and if problem still exists let me know.Horn is usualy located at the front of the vehicle either behind grill or in the engine bay near to the headlights.good luck.
