Horn wont blow

if you push on the horn button you usually hear a relay click. if you do the chances are good the horn is the problem. the clicking relay tells you the electrical is good from the horn pad through the relay and out to the horn. when you find the horn use a test light to see if you have power to the terminal on the horn. if you do then the horn is no good.

The horn switch is driven by relay so you will be looking for a relay that clicks on the power block. You might hear it clicking if you have the keys on. If you do not hear it, it could be your steering wheel button.

If you do not hear a click, then yes, you might have a bad fuse. They do not blow very often. Have you hooked anything else up to the truck that happened about the same time it stopped working?

if you take a test light and test all the fuses in the fuse box and if they are good then when pushing on the horn button you can usually hear the horn relay working(click).if it does then you need to check the horn itself.take a wire and run it from the battery positive cable and connect it to were the horn wire connects to the horn,it should blow(make sure of a good connection),if it does then it could be a dirty connection at the horn.if it doesn`t blow then the horn needs replacing.you can also use the test light and test for power at the horn wire at the horn itself to see if the horn is being feed power from the horn button to the horn.

if the relay is clicking when you push the horn button then i would say there is a problem with the horn, if you can get to the horn tap on it with a small hammer or unplug the wire and test it with a test lite

The click you hear is the horn relay -- this likely has either dirty / corroded connections or burned contacts inside the relay. If cleaning all relevant connections doesn't solve the problem, replace the relay. You can find the realy by having someone push the horn button while you track down the click.

Hi

this might help

Often the horn is a shared fuse with the car radio or interior light. worth a look, also the horn may be dirty inside and therefore wont sound, a good tap with a hammer might free it up again.

a bad ground in the horn button

that sound that uyou are hearing is the horn relay clicking. you will have to go directly to the source which is the horn itself. Try adding power to the horn itself, to see if it will blow. Looking at the age of the car, most likely it will be the horn.

Check fuse for horn and for dash lights. If the interior lights work then suspect dimmer switch for the dash lights. If you press the horn button do you hear a click under the hood or inside the car? If you do not then the fuse is blown and if the fuse is good then the relay may be suspected bad. If the fuse is good and the relay clicks then suspect the horn to be bad. If fuse is blown and you put a new one in and you push the horn and the fuse blows again, then disconnect the horn before replacing the fuse again. Then push the horn button and see if you hear the relay click if you hear a click the the horn is bad or wiring butmost likely the horn. If you have the horn unplugged and the fuse is good and you push thee horn button and no relay click suspect the horn button to be bad. Hope this helps.

Your horn buzzer is either broken, or it is not getting power. The click you hear is the horn relay. It is good that you can hear it.

To diagnose the problem, locate the horn module. It should be behind the grill in the front of the car. Remove the power wire. Get an assistant to press the horn button while you measure voltage in the connector. If you have voltage, replace the horn. If not, find out why there is no voltage. It could be a blown horn fuse or a broken wire. Good luck.
