SOURCE: Air Bag Sensor light on & horn not working

Without knowing exactly what the air bag code is, coupled with the known fact that the horn is inoperative, my opinion for a viable solution is to replace the spiral cable or, as commonly called, the "clockspring". This device is the main wiring connection between the steering wheel and the wiring harness. If the circuit(s) open,due to a failure of the spiral cable, the air bag light will be on, the horn will not work,and , if you have a steering wheel Cruise control, it too may be inoperative. Best solution: replace the clockspring. Best advice: Get the airbag DTC's checked, and if you have an open in the driver side air bag circuit, the clockspring is def the culprit. Given that you had chassis work, your DTC just may be the front crash sensor, and the horn may just be unplugged, or bad, This is the best I can do for you, given the info that you have provided,
Hope this helps, and thanks for choosing FixYa.

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: Need connector block connections for horn wire,relay to button.

The horn switch provides a ground. If you have no voltage at the horn wire, inside the steering whel, I would suspect a bad spiral cable, or clockspring under the steering wheel.

SOURCE: horn fuse keeps blowing out

Check the wiring around the horn and make sure nothing is touching metal...look under the hood at the horn and make sure everything is pluged in and there is no water on any plugs or wiring...Make sure the fuse is the correct number (ex: 10, 20, 25) If it is still blowing out the fuse then you after you do some checking then it is a short in some wires

Horn does not work, diesel engine. it is very faint, bell sound also very faint

Sounds like you may need to just replace your horns. Check for power at the horns while someone is actually pressing on the horn switch ( steering wheel). If you have power, replace horns. If no power, might want to check fuse and horn relay.

2000 Toyota Tacoma Horn Relay location needs replacing

1- The HORN fuse is located in the fuse panel on the driver's side under the engine hood. Of course, if it is "blown" replace with the SAME size or smaller and retest the horn.
2- Verify the horn itself (isolated) using one wire attached to the Main Battery + (POSITIVE) to the spade terminal on the horn. The horn can be accessed after carefully unclipping the fasteners connecting the front grill to the radiator area- just be careful- work slowly. The horn is naturally grounded to the vehicle frame.
3- If the horn sounds with the direct bypass voltage test move to the cab. when you depress the combo horn pad/airbag listen carefully for the relay behind the left under-dash area. If you hear it, then the relay is "closing" but it still may be bad or the voltage from the horn relay is not getting to the horn. I would replace the relay. However, there may still be a wiring problem to the horn.
4- The Horn Relay for the '00 Toyota Tacoma V6 4WD I worked on was BEHIND the cabin fuse panel on the far left driver's side (oh thanks guys). I went to the trouble of pulling down this relay/fuse block- it was not exactly "easy" but I am not a beginner and had the tools and my curiosity and sleuthness prevailed. If the new relay does not fix this issue my next step is to replace the wire from that relay to the horn. Again, not easy but not impossible either. Take you time, use the right tools and materials & check your work. The only other option was mentioned earlier- drop in a new momentary switch (lighted?) into the dash and run a new wire. I would NOT use switched power so it can be used without the vehicle running... I think it is safer. This is a view of the interior panel dropped down. One of the relays can be seen- the grey cube with a empty relay socket just to the right. Why they put these here- is anyone's guess.

Car horn will not switch off i pulled fuse out what is problem

It's either the horn switch in your steering wheel or the relay that powers the horn.
Relays are usually on the firewall or fender wells, both under the hood.
Relays plug on and off easily. Any autoparts store will tell you if you have one on your model.
If it is in the steering wheel, best not to mess with it, if you have airbags.
If no airbags you can try to remove the cover in the middle of the steering wheel and
check the horn switch there. Sometimes these are hard to work on and because you look at the steering wheel constantly, it is a visual bummer if you cant get it back right.
If you want it working correctly, have a shop fix it. If you wish to make it work
yourself, you could go to Radio Shack and buy a Momentary contact switch with
at least a 5 amp rating. All you need to do is connect one side of the switch to ground
(any metal screw that screws into metal-no plastic!) and connect a wire to the other side
and run it up, thru the firewall to the horn. Figure out which wire is the negative on the horn and
unplug it from the horn. Connect your wire to the horn terminal. Now the horn should only work when you press the switch. If the horn has only one wire and it is Positive you may have to run a hot 12 volt
wire from the switch to the horn. Be sure to add a fuse to this setup at the input to the switch. You can
find a 12 volt positive wire under the dash that has power when the key is on. Tap it and add the fuse then connect it to the switch. Run another wire to the horn and you are done. It may sound complictaed but it's not and it will work.

Push on the horn and I here a ckicking under the glove box but the horn does not work

The clicking is the coil side of the horn relay....That pulls in the contact which carries the heavier currant needed for the horn operation.
To work on this fault you'll need an electrical test meter or light....
  • Locate the actual relay by having someone press the horn and NOT hold it down
  • The clicking will lead you to its position.
  • Unhook it from its bracket and with the meter check that the switching side of the relay is closing when the horn is pressed.
  • If not replace the relay.
  • If power is going across the switching side go to the connection on the horn at the front of the vehicle and check the power output there
  • If you have power there, check to make sure the earth contact to the body is intact.
  • The earth contact is usually through the horn button via a contactor on the steering wheel assembly.
  • I would think that that is fine as the relay is operating.
  • if all power is coming from the relay and the horn is grounded correctly, replace the actual horn.

Toyota Tacoma '03 horn sticks

If you are getting water in the fuse box, it could be shorting the system out and in turn the horn would blow. Some manufactures put 2 fuses for the horn too. One for the horn and one for the horn relay. That is another one, maybe the relay is bad or wet. Hope i put some light on your answer. Good luck!!

Horn not working

Three things to check here... First find the actual horn assembly... generally under or near the front bumper or radiator support... pull off the wire and check for power with someone depressing the horn button... if you have power there then it's your horn assembly... could just be rusted to the point of being frozen... I have fixed these by spraying WD 40 into it and tapping on it... If no power then check the horn relay... either get another one from the junkyard and plug it in or put a temporary jumper wire (12 gauge wire) in the large terminals where the relay goes and try the horn... if it blows it was the relay... if still no horn after these tests then it's the switch under the steering might need a puller tool to remove the wheel the most likely problem in that case is a damaged horn ring (transfers juice from the button in the wheel to the horn circuit)... Hope this helps...;-)

Where do I find the horn switch on 95 Jeep Grand Cherokee?

 You should check to see if you have power at the horn first. If you do, you need a new horn. I believe there is also a relay involved. Sometimes these are interchangable. You can take a relay like the one for the A/C and swap it with the horn one and see if the horn works. That will at least eliminate the relay.

Mitsubishi horn doesn't work

first check fuse, should be hot all times (12v) to see if its blown should be, its in the engine compartment relay box, from there check power to the horn relay on both sides should be red and yellow wires going to it. check the wires for power and the relay, from the relay the wiring will split from the there to the horn one way and to the horn switch the other way,check to see if you have power to the horn, it should read .1-.3 volts then when you have someone push in the horn it will close the relay (if horn switch is working that is) and you will have power to the horn on the power side, if you get power to the horn but it does not sound either the horn is bad or the ground from the horn is bad ,horn is located behind bumper if i remember corectly looks like a black seashell, this is every component in the system and if there is not power to the horn switch then that is where your problem is at and why the relay is not closing to power the horn and give sound. any other question about more indepth wire tracing please feel free to let me know.
have a good night and good luck
