You have mentioned fuse and relay are good when activating the horn buttons does the relay sound/click. you can verify the horns are good by jumping connectors 3 & 5 of the relay socket with a fused jumper wire if the horns sounds the circuit and the horns are good. Terminal 2 with a DVOM to ground when activating the horn buttons would test that circuit. If that fails you have a faulty clock spring assembly or what is called a sliding contact.

Get two seperate wires and connect it to terminals of the horn then connect it directly to the battery and see if it will work. if not, then your horn is busted.

SEE IF YOU CAN GET A TEST LIGHT AND HAVE SOMEONE PUSH HORN AND SEE IF POWERS UP. TRY BYPASSING SIGNAL WIRE AND POWER UP HORN TO SEE IF HORN IS THE PROBLEM. IF ALL GOOD THEN IT'S IN HORN PAD,BUT IF RELAY IS GOOD AND FUSES IT MUST BE HORN,NOT UNCOMMON.

SOURCE: 1999 toyota corolla Horn doesn't work.

Usually the wire from the steering wheel is Green w/Red and the wire to the horn from the fuse box is White. There is only one fuse, sometimes shared with the emergency lights. Check to see if there is power to the horn itself with a volt meter.

SOURCE: volvo S60 2005 horns not working

Remove the wire connector from each horn and attach a voltmeter or test light. Have a helper push the horn button while you check for voltage. If there's no power getting to the horns you have to work your way back to the relay checking for shorts. If there is power try holding the horns metal mount against a good ground like an engine bolt or the sub frame. And with wire reconnected have your helper try the horn again. If it sounds then clean rust away from mounting bolt and car (rad support or grill bracket), and look for a loose or broken ground strap to the rad support (from either the battery or engine). If both horns still don't work either they're clogged with snow or dirt (bring them inside to defrost or clean out), or they need to be replaced.

SOURCE: My 1996 jetta horn does not work. Fuse / relay okay

hi did you also checked the horn itselfs. when you take out the horn and look at the back you will see a adjust srew with sealingmastic on it. you can remove the sealingstuff and try to adjust the horn. this only works if the coil is not broken. but first you have to check the connection inside the steeringwheel. make sure the switch in the steeringwheel is making contact to earth. if this all doesnt work you have to buy a new one goodluck.

Horn doesnt work all fuses and relays are good


If you know the fuse and relay have power, you should be able to jumper the relay and make the horn blow. The horn pad on the steering wheel usually grounds the relay. If you can jumper the relay and make the horn blow, the problem may be the horn pad or the clockspring in the steering column.

The horn relay is in the fuse/relay box under the hood. so the fuse is HOT on both sides? you should hear the horn relay click when pressing on the horn switch. there may be other relays in that fuse box to swap with and see if the horns work, if the relay clicks, its "usually" good, but the contacts may be bad. if the relay clicks, check for power at the horn. DARK GREEN wire, if it has power , then check the black wire, thats the ground. If it has power and ground, but does not work, the horn is bad.

Horn doesn't work at all check fuse was good relay was good???


If you're sure the relay is good the only thing left would be to check the wires that connect the horn/s to be sure they are making good contact as they are exposed to the outside elements and may have corroded or come loose. You can also check the power to the horns with a test light while having someone push the horn button. If there is power there I would still suspect the horn relay.

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.

The click you here is the horn relay, You need to find the horns and check for power at the wire connectors. But you probably have a bad low and now a bad high not horn. since the relay clicks your fuse is good so that eliminates the fuse.

The click you hear is the horn relay -- this likely has either dirty / corroded connections or burned contacts inside the relay. If cleaning all relevant connections doesn't solve the problem, replace the relay. You can find the realy by having someone push the horn button while you track down the click.

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.

2004 Hyundia Elantra. My horn does not work either.


if i'm looking at the right diagram, the horn-a/c fuse & horn relay is in the underhood fusebox. if your
a/c clutch is working then you have power there. short of diving in with a multimeter or computer-safe testlight,
i would listen for the horn relay to click when the horn button is pressed. that circuit is hot all the time and the horn switch
grounds the horn relay. if you hear a click then most likely you have a bad horn/s. if you don't hear a click then you have a
bad horn switch or bad clockspring in the steering column. and .... there's always the possibility of just having a bad
connection somewhere in that circuit. if you see another relay with the same part number as the horn relay,
try swapping relays. good luck ........
