Horn does not work

the click is the relay working. proves the earth return circuit is working on the horn button. horns are powered at all times, it is the earth that makes them work. check for power at the horns.

push on the horn button you should hear a click noise. is so then the circuit to the relay and the relay is good. then you find the horn and check for power to the horn with the horn button pushed. if you do then the horn is bad.

It could just be that your horns are bad and need replacing. You got to the horn relay and have somebody push the horn buttons while you hold your fingers on the relay, if you feel it click the your buttons are good and you have bad horns.

Your horn is hooked to a relay. The relay is activated by the ground wire that comes from the horn button. If the fuse is ok then you need to check the relay and the horn switch. You may have a dead relay or a bad contact from the switch.

There is a 10 amp horn fuse either in your cabin fuse box or the engine compartment fuse box. If it is not the fuse, you will need to troubleshoot to find the cause. First, find the horn relay (usually in the engine compartment relay box) and pull it out. Have someone hold the horn button down while you push the relay back into it's socket. The relay should click as you push it in. If it clicks, your problem is probably in the wiring to the horns. You'll have to trace the wires from the horns to the relay box to see if the connector went bad or what happened. If the relay doesn't click, you can try replacing the relay, but the problem may also be with the horn button. To troubleshoot the button, you need a 12 volt test light. You can get one for a few bucks at a parts store or WALMART auto tools isle.
Use the test light to interrogate the relay socket. Remove the relay from it's socket. connect the clip of your test light to the positive side of your battery and then probe all of the relay socket terminals while someone holds the horn button down. One of the terminals should turn the light on bright. Some of the terminals may light it dimly, but at most one will make it bright. If none makes it bright, your horn button is not working or the wire from the horn button to the relay box is cut. If you have questions, please let me know. If you want to understand the relay, see my post at http://www.fixya.com/cars/r6022358-relay_check

Check fuse for horn and for dash lights. If the interior lights work then suspect dimmer switch for the dash lights. If you press the horn button do you hear a click under the hood or inside the car? If you do not then the fuse is blown and if the fuse is good then the relay may be suspected bad. If the fuse is good and the relay clicks then suspect the horn to be bad. If fuse is blown and you put a new one in and you push the horn and the fuse blows again, then disconnect the horn before replacing the fuse again. Then push the horn button and see if you hear the relay click if you hear a click the the horn is bad or wiring butmost likely the horn. If you have the horn unplugged and the fuse is good and you push thee horn button and no relay click suspect the horn button to be bad. Hope this helps.

simple circuit, but can be hard if problem is switch in steering wheel. First check fuse and relay at fuse box. relay should click when horn button on wheel is pushed. If relay doesn't click, either button or relay is bad. If relay clicks, test for voltage at horn. You can use a simple test light available at the auto parts store if you don't have a voltmeter. If there is voltage at the horn, replace horn.
If relay does not click, replace relay to see if that fixes your problem. If new relay doesn't fix, you have a bad switch in the steering wheel or possibly bad wiring. cannot help you with switch as it's different on every car. any questions--let me know.

I replaced the horn relay which is located inside of fuse panel under the hood of car on the firewall, have someone push button to be able to hear a clicking sound coming out of the correct relay, then trade out relay of the same and see if horn works

You have to test the wiring between the relay and the horn. First make sure that you have 12 volts at the relay terminal that feeds the horn, then make sure that the wire on the horn is getting the 12 volts when you push the button. Finally make sure the ground is good where the horn is mounted. If the ground is bad, run a ground wire from the engine block or battery to the point where the horn is mounted.

If all wiring is good, then you need a new horn

If you hear a click the power is working the relay. If no click under dash, possibly bad fuse or relay. If you hear relay, test horn. Unplug horn and run a 12V jumper to see if it beeps. If it doesn't, try to redo the ground and then test. Then if that doesn't work, replace horn.
