When looking for relays, the most common spot is in the relay fuse compartment under the hood, either near the battery OR near the firewall in most instances.

However when troubleshooting any electrical problem, checking all fuses in both the passenger and engine compartment is crucial before moving on.

Use your owners manual or a Haynes or Chilton manual to determine which fuse is resonsible for which circuit or the information is usually located on the inside of either compartment cover.

Good luck.

How can you use wire going to the horn from the relay and put on a push button switch


Find the wire at the bottom of the steering column that comes down from the horn button, or locate the wire at the horn relay.. Cut this wire and splice it to a wire that goes to one side of a push button switch. Connect the other side of the switch to the metal chassis of the car, which is ground. A metal part of the dashboard frame will usually work.Then when you press the button, it will activate the relay and sound the horn.

Horns not working,original relay 43yrs old !


You hear clicking at horns, and not the relay? Maybe the horns went bad, or maybe you need to check and clean the connections there.
Don\'t know why the cab light went dim, unless the horn wire was trying to make contact?
Yes, TJ, the horn wire should be hot. You are grounding that hot wire when you press for the horn. That hot wire comes from the coil side of the horn relay. Press for horn, it grounds the coil side of relay, and the relay can pass power to the horns.
Now back to the clicking no-honker horns: power gets to the horns when relay is energized, and there has to be a good ground for horns to work. I don\'t know if your horns are case grounded or a wire from horns goes to ground, but check the ground there. If case grounded, pull horns off and clean the ground. Also might try a known good horn. Keep at it, sounds like you are almost there.

My 2001chrysler town and country van horn does not work


Check the horn relay to see if it works. Most cars use the same relays for multiple other functions. Check the part number on the horn relay and find another relay that is working that has the same part number. Swap out the horn relay with the known good relay. If that doesn't work, check all the wiring in association with the horn. If all the wiring is sound, then it is probably the horn itself, but that is very rarely the case.

My horn just stopped working on my 88 f-150. everything is still connected to the horn box under the hood. what else could be wrong with it?


Horns die like crazy on these. put power to the horn and make sure it works. The horn button is possible too the clockspring connection at the steering wheel. Find the wire in the harness under the colum that works the horn its black and it's on one end of the connector. with a test light hooked to ground, touch the wire and it should light dimly and the horn relay shough click. if it does the horn is likly or the fuse is blown two wires at the horn one shold be hot all the time and the other becomes grond pushing the horn button if thats good the horn is bad

No horn on my '95 Grand Marquis. I have the owner's manual and one place it says location #5. Then on page 341 it doesn't list #5. Found other wrong references. How do I fix the horn? Fuse in #5 looks...


Your horn works off of the engine compartment fuse box. There will be Maxi fuses and regular fuses in it. The regular fuses there is one 15 amp fuse that fuse is for your horn relay. I don't know what direction they go in but it will be the 5th fuse in that row. Right next to that row of fuses there will be a row of Maxi fuses they should go in this order a 50, 50,40,30,50,40,30. In this same direction of fuses the # 2 relay in this order is your relay for your horn. If you remove this relay you should have 12 volts on 2 of these wires. There should only be 4 pins that are used in that relay even though it has for pins. The 2 power wires both work off of the #5 i5 amp fuse in the engine compartment. If you have power on 2 wires at the relay when it is removed then you will need to chack all the other wires where the relay is for a ground when someone holds the horn button down for you to check. If you have a ground when the horn button is depressed then the other terminal that is left in the relay that you removed I need you to take one of the power wires that has 12 volts and jump it over to that other terminal that is n't the ground wire for your horn when the pad is depressed. If the horn goes off then every thing is ok with that circuit then the relay has probably failed switch it with a simular looking relay in the engine compartment fuse panel then see if your horn works properly. If you don't have a ground at one of the terminals when someone holds the horn pad down. Then the problem is probably between the horn pad and the relay more then likely it is your clock spring in your steering column. Let me know if you need any more information then this.

Need to find the horn relay in a 1993 ford mustang gt I tested the horn and all fuses. I don't have a wiring diagram and chiltons doesn't show the horn circuit


94 was a new model freshening and I have 94. may be similar.

Horn Relay and fuse is in fuse box in engine compartment, driver side in front of strut tower.

Horn System The horn system includes:
  • Dual horns (13832) (one high pitched, one low pitched).
  • Horn blow switch (13A875) which grounds the horn relay, which energizes the horns .

Horn won't stop blowing


If you can locate and pull relay, do that, if not, pull wires off at horn if you can, otherwise pull fuse. If you have other relays same in area of horn relay (same number on relay) try one of them in that horn spot to see if maybe it's just a stuck relay.If you pull fuse for horn, you may find out something else on same fuse, so make sure you check everything else is working.

1985 Toyota Pickup Horn


Probably the switch in the steering wheel, or fuse, but usually horn fuse works other things too such as cig lighter or radio. If everything else is working fine, then to troubleshoot you'll need a testlight. I would start with the wiring harness where the steering collumn plugs in and decipher which wire is the horn wire. Put the test light clip on +power, then check the wires on the collumn side one by one, pushing the horn button on each one. The horn switch is the wire that makes the light blink when you push the button. If you try all the wires and none make the light blink, then its probably a problem with the horn switch in the s. wheel. Does it have an after market steering wheel? Because aftermarket wheels often have crappy horn switches in them. Also could be a horn relay if it has one. If you listen carfully while pushing the horn, you should hear the relay faint clicking. If you hear this, then the switch is working, but the relay might not be. Follow the sound to find it if you hear it. Test all sides of the relay with your light. Should get power constant on one term, and the other two should light when the horn button is pushed. Hope this helps. Cheers.

Where does the 2 wires from the horn connect to on a 1994 Jeep YJ


You should really have the service manual at hand; they will contain color coding of all of the wiring. Either Haynes or Chilton will have all the electrical diagrams and the most serivce work you can do at home on the mechanical stuff. They cost between 20-30 dollars US and can be had at auto parts stores. 

Many horns are not directly controlled by the horn button but by a relay on which the horn button works.
