Test your car's electrical system with a different horn, other than the possible faulty one or test the horn itself, outside the car with a different power source, this is to isolate which is faulty , the car's electrical system or the horn itself, if horn is faulty then replace it, if not check your wirings.

Testimonial: "Thank u guys for the suggestion tore the steering wheel apart a figured out it was missing parts. So here goes aftermarket horn. I did check output and it was 0.00. That is when I took steering wheel apart. Noticed wire hanging. Couldn't find a pic of how it worked. So I will put aftermarket horn on it. After all I am a expert wireman. Thank you guys for your help and happy New Years to you and yours"

SOURCE: where specifically does the AC

When you take the cover off the relay box, flip it over. There should be a detailed diagram on the inside of it. You should see the initials for A/C and and Horn, Horn may be labled as H, or will say Horn.
Please let me know if you need further assistance.

SOURCE: 1986 Toyota Pickup Instrument lights and tail lights out

Even though the relay is activated,I assumed you checked the out put?Also,You checked the voltage at the light sockets?With a meter,or test light ,check the fuse for the cluster lps,adjust them to dim,and to bright,the meter should act accordingly on the fuse.If it does not,replace the dimmer control,or head light switch,witch ever controls them.This may allow continuity to the tail lights as well.If the fuse is dead for the cluster lights,replacing the dimmer control,or head light switch will solve the problem,or,from another fuse ,supply voltage to the cluster lp fuse,one that is only hot with the key on,cause if you do this the dash lights will come on,every time you run the vehicle,day,or night.

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.

How do I connect a hooter (horn)from beginning to end please.


If you intend to use stock horn button, wire from it needs to go to a horn relay. Big amp wire from battery goes to one side of relay, wire to horn out of other side. Good idea to put fuse in there somewhere.

2000 VW Jetta TDI my Horn just stopped! I don't know which relay to start by, The fuse is good but no V at horns Is there a wiring diagram to be had?


There is a "clockspring" wiring spiral in the steering wheel to accommodate the rotating steering wheel with controls on it. If this breaks, you may lose some or all functions controlled by stuff on the s-wheel.

Need a fuse box diagram for a 2004 mercury sable. Horn stopped working


1) Check for power to horn unit with steering wheel horn switch depressed. If power present, replace horn unit.

2) Check horn switch operation. Repair or replace.

3) Check continuity from driver's horn switch mechanism and horn wiring. If faulty, then trace wiring back to fuse box and relay assembly.

Make sure you haven't skipped any steps before attacking the fuse box issue.

I have a ford F150 2001 and the horn wont work.


Could be the fuse for the horn, the horn relay or the clock spring in the steering wheel column.

Best to start with jumpering the horn relay, to check the horns to the fuse.

Take a jumper wire, and jumper across the normally open contacts in the horn relay socket ( listing in the owners manual ). This is shown as the red line in the picture below.

If the horn does not work with the jumper wire, check the fuse ( engine compartment fuse # 7 ) with a meter. IF the fuse has power on both pins on the back of the fuse, next is to install the jumper and test the horn connector for power & ground ( Yellow w/ light green is from the jumper in the relay socket and black is ground ). If you do not have power using the Yellow w. Light green wire & the black, try another ground, to see if it is an issue with the ground wire. This is to a ground lug on the passenger side inner fender.

If the horn does work, check pin #2 with a meter set to continuity from pin #2 ( diagram above ) and a known good ground. While checking this, have someone press the horn switch on the steering wheel. If you do not get a low resistance (

I can not find horn fuse or relay


The first thing is to check the fuse and if thats sokay then check the horns they may be bad, if you use a testlight and have someone push on the horn button and see if theres power to it, if theres power then the horns are bad if theres no power and the fuse is good then you may have a bad horn relay or a problem with the horn buttons or a wire in the steering column,okay lets start with the fuse location, the fuse box is located on the leftside of the dash behind the trim panel, i have enclosed the fuse box diagram and circled the horn fuse which is in location #14 and is a 20amp fuse, take note that the horn fuse is the same as the lighter and glovebox light and power antenna, so if those things are working its not the fuse but you can check it anyway,the horn relay is located on the pass/side of the dash to the right of the glove box under the dash,there you will see a relay box with alot of relays, the horn relay is slot # 2, i enclosed a diagram of its location and the relay spot, hope this is helpful .goodluck.johnjohn2_65.gifjohnjohn2_66.gifjohnjohn2_67.gif

Hi my grand voyager se 3.3 has lost it's mind. my cruise and horn dosen't work. The abs and airbag light is on. When it warms up the transmission will not change gears. I have changed the output speed...


I'd check those issues one at a time. Note the horn wiring diagram. I got the horn diagram because it is simple. The fuse is hot all the time, not only check the fuse, use a test light and check voltage at the horn fuse. The fuse and horn relay should be in power distribution center under the hood. If you pull relay and use jumper wire between terminals 30 and 87, with terminal 30 hot all the time, the horn should sound, If it does, problem is on control side of horn relay, left side, has to have voltage and ground. Top wire is voltage, bottom wire is ground. The wiring in steering column--clockspring--horn switch are all part of ground for the control side of relay. If the steering wheel has an airbag, have to disable and be careful with it when testing horn wiring circuits in the steering column.
Granted, your other problems maybe more involved? Check for applicable trouble codes

The horn in my 99 ford f-150 isn't working. I was wondering if there was some common problems with this and how hard it would be to diagnose and fix the problem.


You can start by checking the horn fuse in the engine compartment, fuse # 7.
If this tests good with power on both sides using a meter, next jumper the horn relay, normally open contacts. The horn relay is relay # 205 in the engine compartment fuse panel, it is the half size ISO relays. use the picture below, to find the correct pins in the relay socket to jumper with a wire.

IF the horn works with this, I would suspect a problem with the clock spring in the steering wheel. Do the other items in the steering wheel work ( cruise control ) ?

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!
