How does the horn work?

Most passenger vehicle horns are electrically powered, and mounted near the inside of the front bumper. When the horn button is pressed, electricity is allowed to flow through the horn circuit, through the fuse and relay, and into the horn. Once there the electricity is converted to sound waves, and the horn sounds.

Failure of the horn will simply result in loss of horn functionality, or a weak horn sound being emitted.

Can I drive with a horn problem?

A failed or ailing horn should not affect any other components. However, horns are legally required safety features, and may cause the vehicle to fail a safety inspection if inoperable.

How often do horns need to be replaced?

Horns rarely fail on newer vehicles, as they have no moving parts. A frontal collision, or salt and water intrusion from inclement weather are more likely to cause the horn to fail than age.

I've searched through the fourms for an answer but didn't find anything I could use so far.

I purchased the grand cherokee a year ago and during my entire ownership the horn has never worked. I push the horn button and i can hear the horn relay 'click' but that's all I get for noise. My question is: where is the horn located? I'm begining to think that I just dont have a horn at all because i've searched under the hood for hours and i havn't seen anything that resembles a horn. I've purchased a replacement and now i just need to know where to look for the cable(s) to hook it up.

This is a 2001 grand cherokee. Automatic, basically the base model with no real add on features (no fog lights or anything that doesn't come standard). Any help would be greatly appreciated. I know i'm a newb, but i did give the forum's a once over looking for my answer so i'm sorry if i missed some obvious post about this.

I drive in Boston and i've become this passive driver that has no retaliation other than flicking my highbeams. I need a horn!!! ;)

The horn is behind the bumper on the passangers' side. To look at the horns (one high and one low tone), place a blanket on the grround, lay on your back and look up behind the bumper. If you have fog lights, the horn is in the same compartment/general area.

I do not like buying parts from the dealer but, I bought mine from the dealer so the the waterproof connectors would match up. The horns from Autozone and other parts places will work but the connector will have to be modified.

If you haven't fixed it yet be aware that most aftermarket horns are ground by the body not by the factory wire. The wires you need will be dark green with a red stripe and black. The dark green wire is positive and black is negative. The factory horns will work with other factory horns but aftermarket will need slide clips installed. It shouldn't take you more than 1 hour at most to do this job. I just recently did my 2002 because it had no horn also, due to being in an accident. I bought the Jeep because it was cheap and I had a ton of parts for the 99-04 WJ. I replaced my horns with horns from a 2005 Dodge Charger because they are louder, and the brackets (after taking the lock in tab off the bracket) fits perfectly behind the grill at the hood latch mounting support brackets. I mounted them just behind and below the grill. Those will be 10MM bolts holding them on at the bottom but you do not have to remove the bars completely. Let me know what you do! I love hearing from DIY mechanics!

The horn is an important safety feature in your Jeep Grand Cherokee. Driving your vehicle with a broken horn can be dangerous for you and others on the road. If the horn does not honk in your Grand Cherokee when you press the button on the steering wheel, it can have various causes. What these are and what you can do about it, we explain in this article.

Some of the common causes that stops the horn from working normally on your Jeep Grand Cherokee are blown fuse, bad relay, faulty horn, corroded or worn out connector, broken wire, broken clock spring or bad horn button.

1. Blown fuse

The horn on Jeep Grand Cherokee needs electricity to work. In case of a faulty fuse, the circuit is interrupted and the horn can not work.

Check your Grand Cherokee’s owners manual or the fuse box cover to find the exact location of the fuse for the horn. If the fuse is blown, replace it with a new one with the specified amp rating.

Comparison between good and bad fuse.

To check the fuse, pull it out of Grand Cherokee’s fuse box using a fuse puller or needle nose plier and hold it against the light. If the metal strip is broken in the middle, the fuse has blown. You must replace it with one of the same amperage and therefore the same color. It does not matter in which direction you insert the fuse.

2. Bad relay

Relays are electromagnetic switches that are used to switch electrical loads on and off. A bad relay can also be the cause of horn failure on your Jeep Grand Cherokee.

A horn relay is rectangular or square shaped with 3 or more legs at the bottom.

First of all, you should find out where the horn relay is located in your particular model of Grand Cherokee. The information may be listed in your vehicle’s owners manual. Typically relays are located in the engine compartment or under the steering wheel on the left-hand side. If you are lucky, the wiring diagram will be drawn on the facing. Before starting the replacement, you must always disconnect the vehicle’s battery.

As soon as you have identified the relay for the horn, you should check whether there is an identical relay in the box, typically you can use AC relay to test the horn relay. With this you can easily test whether the electromagnetic switch is actually the cause of the malfunctioning horn on your Grand Cherokee. Most relays are plugged in, but they can still be relatively tight. Be careful not to damage anything when removing the relays. Remember: The battery should be reconnected after replacing the relay – otherwise no current will flow.

3. Bad horn

A broken horn could be the reason why you can no longer honk on your Jeep Grand Cherokee. Horns rarely break down, they can last decades and can even outlive the life of the vehicle. Still, it can fail depending on how often you use it. In particular, if the horn is working but sounds off, it’s because one of the horns has worn out.

You can test the horn on your Grand Cherokee by checking the voltage at the connector or with a test light.

4. Broken wire or bad connector

The horn sits at the front of your Jeep Grand Cherokee where grime and other small particles can build up over time. This can lead to corrosion on the connector resulting in poor conductivity. You don’t necessarily have to replace the corroded connector, in most cases the connector can be cleaned with WD-40. For safety reasons, make sure the battery is disconnected when cleaning the connector, and the connector is fully dry before you plug it back in.

If you don’t see any corrosion on the connector of your Grand Cherokee, then its time to perform the voltage test with a multimeter, or you can also use a test light. Turn on the multimeter and insert the probes into the connector, one at each point making sure the metal part of probes don’t touch each other – otherwise it will short out and blow up the fuse, and may cause damage to the vehicle’s electrical system. After inserting the probes, ask a friend to press the horn button in the vehicle. The multimeter should read 12+ volts, if it reads 0 volts then it indicates conductivity failure in the horn system: a broken wire, bad connector, broken clock spring or faulty switch can be the cause other than blown fuse or bad relay.

Multimeter should show 12+ volts at the connector when you press the horn button on the steering wheel of your Grand Cherokee. If it shows 0 volts, it means the horn is not getting any current.

Rodent Damage: If bite marks or the like are discovered, there is a high probability that a rodent has let off steam in the engine compartment of your Grand Cherokee. Then it is important to carefully examine all other cables and hoses for damage, including electrical wires for the horn.

5. Broken clockspring

The spiral cable or clockspring is a spiral-wound special rotary electrical connector in your Jeep Grand Cherokee which allows the steering wheel to turn while still making an electrical connection between the buttons on the steering wheel, including horn button, and the vehicle’s electrical systems. The clockspring is located between the steering wheel and the steering column. The clockspring contains delicate wires that can get damaged during servicing or due to overuse if the vehicle has put on too many miles.

If the clockspring is damaged in your Grand Cherokee, you may see other system malfunctions as well. For example, the airbag warning light may illuminate in the instrument cluster, or other buttons on the steering wheel may stop working. But in rare cases, it is possible that only horn wire in the spiral gets damaged.

It is not feasible to repair a damaged clockspring. They are relatively inexpensive and once found defective should be replaced with a new one.

6. Faulty horn button switch

Another reason for non-functioning horn can be failure of horn button in the steering wheel of your Jeep Grand Cherokee. Over time, depending on how frequently the horn has been used, the button may eventually wear out and cease to function.

Conclusion

There are many reasons why the horn may not be working in your Jeep Grand Cherokee. When looking for the reason, you should always start with the most obvious cause, blown fuse or faulty relay.

In any case, it is advisable for laypersons to visit a workshop as you can easily do more damage to your vehicle, especially to the electrical system. An expert mechanic can diagnose the issue while you sip coffee in the waiting area.
