Most passenger vehicle horns are electrically powered, and mounted near the inside of the front bumper.
When the horn doesn`t beep when you press the horn switch, the most common cause is the fuse. The fuse may be in the cabin or under the hood, but this information is available in the owners manual. Check the fuse, and if it is burnt out you can replace it with one of the spares in the fuse box.
The fastest way to make a malfunctioning horn stop honking is to pull the horn fuse or the horn relay. Failing that, if you are unable to immediately locate the correct fuse or relay, pulling the main fuse or disconnecting the battery will also allow you to address the problem without damaging your hearing.
The horn works using electric power and, just like any other electrics-dependant part, it has a fuse. If the fuse is blown, you`ll simply need to replace it.
If the horn makes no sound or sounds different, or if you cannot hear a click from the relay when the horn is pressed, replace the horn relay.
Most cars on the road today have two horns, with both controlled by a single horn unit located under the hood. Lift and secure the hood, find the horn, typically fastened to the front firewall or behind the vehicle`s grille, and unbolt the unit.
Car horn switches, or buttons, are typically mounted in the steering wheel. Some steering wheel buttons are mounted off to the side of the steering wheel, but most are located directly in the middle of the wheel. Most horn switches are normally open, which means they only close when the button is pressed.
Locate the car horn, which is usually either behind the car`s grille or on the radiator core support. The horn usually resembles a fuse, with wires coming off it.

The headlights wont shut off and the horn keep honking when I turn them on.
ANSWER : It sounds like you have a rubbed through wiring harness or two. All the components you mentioned are switched on the ground side. That means if there is a short to ground on the switch side before the relay, then the light will turn on. This would lead me to think that there is a rubbed through harness in the steering column. This will not blow a fuse though.

The light or horn will simply turn on without you moving the switch. The fuse for the taillights and dash lights is a different concern. A short to ground on the positive side, after the relay will blow a fuse. It will only blow the fuse when it is switched on. This could mean a short in any positive wire in the taillight circuit. There are a lot. Every switch that illuminates when you turn your parking lights on could be shorted. Any taillight or parking light circuit, too.

Here are some tips. There is only one way to find this type of problem – it will have to be visually traced. Follow the harnesses with your eyes and look for damage. Use the clues that the car is giving you to narrow your search. The wires will need to repaired after the problem is found. If you need help having this diagnosed and repaired, a certified technician from YourMechanic can inspect your electrical system and let you know what fixes need to be performed.

I have a 2013 Hyundai Elantra with keyless entry/start. Lately when I push the ignition button to start my car the horn honks.
ANSWER : Hi there. Most of the time this occurs when the key fob battery gets low. If the battery is replaced then it should be fine. If the battery does not help then there may be a programming issue within the security system and the ignition switch. I usually either try another remote or I replace the battery and test it. If the problem persists then I check the computer programming to make sure that it is properly registering the fob. If not then it may need to be reprogrammed. Some of the time the module needs to be replaced. If you want to have this starting problem checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

2006 Jeep Commander horn problem
ANSWER : Hi there. Check the wiring from the horn button to the horn and see if there is any loose wiring or any burned wires. If all the wiring looks good, then the issue is within the steering column. The horn plate could be going to ground before the button is pressed making the horn active all the time. If you need further assistance with the horn not working correctly, then seek out a professional, such as one from Your Mechanic, to help you.

Horn honking when locking the car
ANSWER : Hi there. Yes, I believe your Toyota dealer can customize both the "On/Off" and buzzer sound level for "signaling" like you mention. Pg 493-495 of your Owner Manual outlines customization which your dealer can make to default settings. These include "normal" signaling methods (light flicker, sounds, etc.). This might be worth checking with a different Toyota dealer, or calling Toyota Customer Service for more in-depth help with this.

Will the front shocks and struts for a 1999 hyundai elantra fit on a 1999 hyundai accent?
ANSWER : Neither the strut assembly, nor the individual assembly components, for those two models in that year do NOT interchange in any parts catalogs and thus these parts cannot be interchanged on the two Hyundai models. YourMechanic can obtain the correct struts for your specific vehicle and professionally install them. If you desire that service, please request front strut replacement and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Horn honks randomly
ANSWER : Hi There,
There should not be any connection between your tires being low and the horn honking intermittently. The cause of the horn honking randomly is likely related to a short in the electrical system. The horn switch in the steering wheel activates a relay when the horn is pressed, which then triggers the activation of the horn. I would suggest having an expert from Yourmechanic come to your location to diagnose and inspect your vehicle.
