A functioning horn is an essential safety component of any vehicle on the road. The horn assembly refers to the system that allows you to sound your car’s horn. This usually includes the horn button (located in the centre of the steering wheel), the horn relay, and the horn(s) which are usually located under the bonnet.
Below are the top three symptoms that could indicate you need to replace your horn assembly:
Your horn makes no sound when the button is pressed
Your horn is too quiet to be heard by other road users
Clicking sound from the horn relay
Our certified mechanics will:
Inspect the entire horn assembly and identify the part(s) that need replacing
Disconnect the battery
Replace the necessary parts, either the button, relay or the horns
Reconnect the battery and test the horn
Hey Fixter, can I drive with a failing horn assembly?

When the horn button (usually located in the centre of the steering wheel) is pressed, an electrical signal is sent to the horn relay, allowing power to flow to the horn(s) which are often located under the bonnet. This circuit is known as the horn assembly.
A functioning horn is an essential safety component of any vehicle on the road. As a driver, you’ll use the horn to warn others of your vehicle's approach or presence, or to call attention to a hazard on the road. In fact, if your horn is missing or broken and does not sound when pressed, then this will result in an MOT failure. So to avoid hassle and money in the long run, it's best to have a broken horn replaced as soon as possible.
In an ideal world your horn assembly should last the lifetime of the car, but there are instances where this is not the case. Just like any other electrical component in a vehicle, there will be times when the horn will need replacing due to corrosion, bad wiring, water damage or a faulty relay.
The functionality of your car horn will be checked as part of your MOT. A faulty or quiet horn is classed as a minor on the test, however if your horn is inaudible to other road users this will result in an MOT failure. To avoid the hassle and cost of an MOT fail, it’s best to have your horn fixed as soon as you notice an issue.
Car horns are located just under the bonnet so they’re exposed to rain, debris and other nasties. If this dirt or rain gets into the horn’s innards, it can short out the circuit and break the vehicle horn (and blow the fuse in the process). However, a horn assembly consists of multiple components which could also affect the functionality of the horn. For example, a broken car horn can also be caused by a bad horn switch in your steering wheel, a broken “clock spring” under the steering wheel, a faulty horn relay, or bad wiring.
As soon as you notice that your horn is not as loud as it used to be or if there is no sound at all, you should have the horn assembly looked at by a mechanic as soon as possible. Without a working horn you could be a danger on the road and your car will almost certainly fail its next MOT.
Usually, there a few signs you can look for:
Your horn makes no sound when the button is pressed
Your horn is too quiet to be heard by other road users
Clicking sound from the horn relay
Burning smell from under the bonnet
During the repair our certified mechanics will:
Inspect the entire horn assembly and identify the part(s) that need replacing
Disconnect the battery
Replace the necessary parts, either the button, relay or the horns
Reconnect the battery and test the horn
A horn assembly is built to last the lifetime of the car, but there are instances where this is not the case. Just like any other electrical component in a vehicle, there will be times when the horn will need replacing due to corrosion, bad wiring, water damage or a faulty relay.
No, you should get your car horn fixed to ensure you are safe on the roads. It is both unsafe and illegal to drive with a broken horn, as it is an essential safety feature in your car. Failing to replace a broken horn will also result in an MOT failure.
