    First, try jumping the horn from the battery to see if it functions.



    If the horn works, it's probably the horn button in the steering wheel malfunctioning.

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

cut back the positive wire enough to check the voltage on good wire , not just at the plug. if you still have bad voltage check the ground to see if you are getting decent continuity! if all is still no good replace the wire from the fuse block to the horn. this is not as scary as it sounds and then you'll be back on the road good luck

horn is under the hood. usually right against the grill or mounted on fender well. fuses for horn can be under the dash, or in fuse panel under the hood.

SOURCE: horn does not work

If the relay clicks then it sounds like its working you will need to locate the horns and make sure they are connected if they are then horns are bad.

OK, try to use a test light and connect the horn lead to ground to see if there is current, and to see if it sounds. If it does, then the wiring is fine to the horn itself. The relay may click, but are the contacts ok? Maybe swap out the relay for a new one.

2007 cobalt horn relay location


The relay is located in the under hood fuse / relay box . Marked HORN PCB relay , If you change it out an horn still doesn't work ,you can test to see what is missing right at the relay . Two of the pins at the relay socket should have battery + , one should be open an the other should show ground 0 ohm's . If you look on the side of the relay there is a diagram of the pins. 30, is Battery +, 87 goes to the horn . When you push the horn button on the steering wheel it causes the relay coil to energize closing the contacts in the relay sending power from pin 30 to pin 87 down to the horn turning it on ! Pins 85 an 86 are the control side , one should have battery + an other should be open , till someone pushes the horn button . You can test for power with volt meter an test with ohm meter for ground on the one , an a open on the other one, an have someone push the horn button an it should change to 0 ohm's .

My horn no longer makes sound i checked the fuse it is fine


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.
Hope this helps... Dale

Horn does not work. Clicks when button is pushed.


Check the wires on the horn. Wiggle them while someone activates the horn button. Next connect a hot wire from the battery directly to the horn. If there is no change the problem is probably a bad horn.

My horn is not working at all on my 2005 prius??? What to do??


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

I just bought a 2000 Saturn SL 4-dr sedan. It's in great shape, but the horn doesn't work and the dashboard light don't work. Is this a simple fix with replacing the fuses or dash light or is it a little...


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.

Bought an 2004 honda accord and the horn does not work. What is the procedure for repairing this issue?


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.

Horn not working changed relay fuse is good.


Could be the horn button on the steering wheel, (When you push the button on the steering wheel do you hear the relay click on?). Other than that the horns are bad or the ground wires on them are corroded. (Pull the signal wires off the horns and try to sound them with a wire connected to (+) positive on the battery, be careful, you can get a shock engaging a horn with power.)

1996 Saturn SL. Horn doesnt work. Fuse is ok. Can't find horn under hood.


it is behind bumper drivers side. I believe there is a relay in the horn, making the horn unique and origional replacement required. if it has three wires in it then it has built in relay.
