How To Fix a Car Horn In A Few Easy Steps?

You are here to figure out how to fix a car horn. Well, you have come to the right place because it is imperative to have a car horn that works for a few reasons. First, having a working car horn can help other vehicles around you and pedestrians know you are around. This way, you can prevent accidents and awful collisions. Secondly, a horn can be perfect pulling in the driveway and alert your family you are ready to go. Still, there are times when a car horn fails at the worst times. Hopefully, this will not happen to you at the direst of times. However, if your horn ever does fail, you need to fix it as soon as possible. Check off these individual component steps to make sure that you get your horn working again soon.

Fix A Car Horn

Looking At the Fuse

The owner’s manual can help you find the fuse box with ease. In most vehicles, the fuse box is close to the driver’s side dashboard. Other times, you can find this near the engine bay. Once you find the fuse box, look at the back panel of the box. There is a diagram that can show you where the fuse for the horn is. If you cannot find a diagram, check the manual for more info. When you find the right fuse, pull it out with pliers.

Having A Relay Check

After you have checked the fuse, while still having an issue, you need to look for the horn relay. Under the hood of your vehicle, you can find the relay box. Unfortunately, the only way to figure out if the relay works or not is to replace it with another relay. Luckily for you, most businesses will swap out relays with you to give you the identical one. If the relay works after a replacement, but the horn still does not work, it is time to move onto the next step.

Relay Switch Test

The relay switch should be next on your list. By using a multi meter, use the Ohms measurement to proceed with the relay switch test. When you remove the relay, use the multi meter probe at the car’s battery negative terminal. If you have a family member or friend around, they can help you press the horn button on your steering wheel. To this point, if you see “out of limits” on your multi meter, then your relay switch has gone very bad. A replacement should be at hand. However, if your relay switch is good to go, it is time to move onto another possibility.

Horn Switch Workability

After the relay switch, it is time to move onto the horn switch. Unfortunately, this step is going to be the most difficult to fix. The horn switch is in the pad of the steering wheel. First, remove the wheel pad to get to the switch. However, you will likely run into an airbag after removing the pad. You should be very careful when working on this. If you do not feel confident working on this step, it may be time to take the vehicle into a trained mechanic who can get it done quickly. Still, you will have to fork out some money to make this happen.
