How To Change Car Horn

Horns are typically placed in front of vehicles, where they have constant exposure to rain, dust, and road chemicals.

Now, whether your horn is dead, or it has just gotten a weird sound, you may want to change it. Of course, one obvious option is to refer to a mechanic. That is an easy solution; however, it may cost you way more than what it deserves.

So, why not change the horn yourself. You will save some money, and who knows, you may also end up enjoying it. Keep reading to learn how to change a car horn in 6 simple steps, even if you are a complete amateur.

Learn How To Change Car Horn In 6 Steps

Step #1: Preparatory Works

Before replacing the car horn, it is important to follow some safety tips. However, you don’t need to panic; there is no potential danger in replacing a car horn. We are just trying to be super protective.

So, the first thing would be to wear protective gloves. Again, your hand will touch nothing dangerous; gloves are to prevent your hand from getting dirty or being scratched. 

Next, make sure that your workplace is not slippery. Of course, this has nothing to do with horn replacement, it is just a general safety rule. Also, if available, wear non-slip work boots.

After that, disconnect the negative battery cable and put it somewhere safe. This may be the most important safety step. If not disconnected, it can result in short circuit currents of hundreds of amperes and heavy sparks.

Finally, remove the horn circuit fuse from the fuse box, and you are ready to change the car horn.

Step #2: Remove Front Bumper Cover

To remove the front bumper, you will first need to unscrew and remove the beauty cover. There are some misconceptions about this. Many people think of the beauty cover as the bumper itself; however, it is made to conceal the real bumper and give your car a nice look.

When you are done with the beauty cover, you will reach the bumper. The bumper is held tight by plastic clips. Pry out these plastic clips; you can use a screwdriver or any other tool with a flat shaft. Once the clips are exposed, pull the front bumper cover away. 

Step #3: Remove The Dead Horns

It is easy to locate the dead or damaged horns. If your car bumper is away, they will be right in front of you. Carefully disconnect the electrical plug connections connected to the horns. 

Usually, horns are attached to a holder, which is tightened to the car. First, untighten the holder from the car. Of course, you will need to unscrew it. Then, disconnect the horns from the holder; you will need to unscrew this too. Once you unscrewed the horns, gently pull them to see if they depart. 

If you have unscrewed the horns from the holder completely, they will depart. However, because they have been fastened together for years, you may need to use some force. There isn’t much to do with dead horns; thus, once disconnected, you can throw them away.

Step #4: Install New Horns

In this step, you will basically undo what you did in the third step. First, fasten the new horns to the holder. Then, put the holder in its position (front of the car) and screw it. Try to be creative, there may be times when your new horns don’t fit the holder. Try out different positions; you will find a solution. 

Once you are done with fastening horns to the holder and to the car, it is time to install new horns. Connect the electrical connections to your new horn and make sure they are tight. Before proceeding to the next step, once again check if everything is screwed. Especially check the holder; it shouldn’t be loose. 

Step #5: Time To Try New Horns

Connect the horn circuit fuse and run a functional test. There is a great chance that the new horns will work. However, if they didn’t, the reason could be either a loose electrical connection or that the new horns don’t function.

To check a loose electrical connection, first, disconnect the circuit fuse and then aim for tightening the plugs. Once done with the tightening, connect the circuit fuse and run another functional test. If the new horns didn’t work this time, too, then probably your new horns are broken. 

Step #6: Clean Up The Mess

Hopefully, your new horns function properly, and you would be satisfied with their sound. Then, your final duty is to get your car together. 

You will need to place the front bumper and its beauty cover in their original positions. Placing is way easier than removing; so, if you were successful at removing them, you will do this more easily.

Make sure that both the bumper and its beauty cover are screwed tight. After all, you wouldn’t want them to fall when you are driving. Also, be extra careful with the beauty cover. It is delicate, and you can scratch it easily. 

Wrap Up

Various incidents may lead to your car horn destruction. Regardless of the reason, once damaged, you will surely need to change it. While referring to a mechanic is an easy solution, it is not cheap. Not fun too.

Thus, we suggest you learn how to change a car horn, and do it yourself. It is pretty easy and straightforward. And fun. First, follow some safety tips. These tips are just to make sure nothing bad happens, even if you are super unlucky.
