SOURCE: 99 CAVALIER HORN RELAY LOCATION

If your horn isn't working and it isn't the horn itself the next thing to check is the horn wire in the steering wheel under the air bag. The little clip breaks off in time and the horn wire pops out. To repair you can remove the wheel and replace the part but I usually grind in a new notch in the old plastic and re attach the wire and it will work again.
Test the horn itself first. Just remove the connection to the horn and attach 2 wires to a live battery and tough the 2 sides of the contacts on the horn. If it blows the horn is good. If not replace the horn before you go any further.

SOURCE: where is the horn located

open the hood, look straight down and you will see it in front of and to the right of the radiator, beneath the driver side head light assembly. Save your self some time, pull the two wire plug connector off and jump the horn directly to the battery with a jumper wire made from an old extension cord. If the horn honks, it is good, if not, go get a replacement at a junkyard and replace the it. Look in your owners manual for fuse panel locations, there is a small one under the hood and a larger one to the left of your passenger's knee under a velcro panel. The horn relay will be plugged into one or the other.

Have had 1989 Lincoln Mark 7 LSC for 5 years she never failed to start. One day she wouldn't start thought mabey she was out of fuel put in 2 gallons. Still no go. Found fuel pump was not running. Shutoff...


Generally a relay is used instead of a fusses. Look under hood for a relay panel.. substitution is the easiest way to find failed relay.
I had similar symptom on my Towncar....found that adjacent relays were same part number. Pulled the horn relay....substituted it for the fuel relay...then replace with a new one.. Did not leave the defective one in place of horn relay. There may be other circuits on the same relay. Be careful !

I have a 1990 oldsmobile 98 and every day i have to get a boost to start it. what's the problem


it is the automatic load leveler that pumps air into the back shocks to level the car so it rides better when there are lots of people or weight in it. it is in the frontof the car opposite the battery, just disconnect it. had the same problem on my 1990 olds 98.

Horn and cigar lighter not working on 1982 corvette - need wiring diagram


Visually inspect horn make sure its not corroded and wiring is on it tight. Then use a voltmeter and when horn button is depressed 12v should register on the meter. If 12v are there and horn doesn't sound the horn is defective. If 12v does not make it there then its either the relay or clock spring (located inside steering wheel) most likely. A visual inspection should pretty much do it with the clock spring (corrosion ,wear of contacts). Relay must have B+ going to it at all times and coming out only when horn is depressed. good luck

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!
