Based on this being a radio station thing, and me not finding anything obvious like a car horn psycic app or anything I am assuming this is a cheap radio station set up.
You have to determine the cause first. Check the horn switch and contacts, fuse, relay and the horn itself.
The horn itself has failed The horn contacts/switches on steering wheel are dirty or broken The horn relay has failed The horn circuit fuse blew Wiring and or connections are corroded or broken
Reconnect your horn and turn your key to unlock the door this will disable your alarm.
I have the same car and had the same problem. It is just a fuse. You may notice that your gas tank doesnt open either. The fuse box is located next to the gas pedal and there is an extra fuse inside the box. Read the manual to figure out which fuse it is but after you change it, the horn and gas tank will work fine.
On my 98 Accord EX, the horn contacts in the steering wheel became corroded. Now the horn only works when I press the horn button and rock the steering wheel. Honda said that it would cost over $800 to repair it because the contacts are integrated with the air bag and the whole thing needs to be replaced. I may spray it with electrical contact cleaner from Radio Shack. If that doesn't work, I'll drive it into the river.
If a Lincoln Town Car's horn whirls then the horn is broken and will need to be replaced. The horn is located in the bumper towards the front of the car.
Electrical problem, Bad button/horn.
I think the fuse is not good
Most mechanics would agree that if your car horn does not work, there are no large problems with the car you should be worrying about. Consider the car horn to be an extra item, not connected to a cars engine or main mechanic system. A car horn is however, important to communicate with other drivers, so it is very important to stop by a mechanics, oil change, or even tire retailer to get the horn fixed.
My 1995 town car horn does not work, sometimes it work one times when I start the car. I have a 1994 Town car and my horn and cruise only work when the adjustable steering column is in the lowest setting. Haven't figured it out yet.
no power to the relay, whats the point of a horn when the key is off?
A horn might not work on a 1996 Honda Accord because of a blown fuse. There is also the possibility that the wire was cut or damaged. The horn is part of the security system. A used car might have the horn wire cut because the previous owner was annoyed by the horn blaring when someone came near the car.
START BY CHECKING FUSES M
I invented the car horn
Push the car horn button....
What is the decibel level of a car horn?
You should in the UK, as your car will fail the MOT test if your horn does not work.
