Five Common Car Horn Problems

Your vehicle can have different types of car horn problems such as sounding lower than it should, no sound at all, and sounding louder than recommended. These problems can arise due to several factors such as blown fuse, broken support and corroded wiring, causing problems in the proper functioning of the horn and causing defects in the steering wheel contact.

When the horn suddenly stops working, drivers will only find out when they need it most. To save yourself from the surprise, check out the list of common causes of horn problems in cars to have a safe journey.
Blown Fuse
Generally, the most common car horn problem is blown fuses, so this should be the main point when looking for the problem. Car horns function with electric power; therefore, if there is a blown fuse the electricity cannot get through and ultimately the horn will stop working.
The possible causes of a blown fuse include a short circuit, overloaded circuit and damaged wiring. You can check the car’s fuse box to confirm it further.
Bad Horn Relay
Another common car horn issue is bad horn relay. Horn relay is a component of the car’s horn circuit. If your horn fuse is working, then there is a high chance that the issue is with a relay. You can find a horn relay in the main fuse box, right into the engine compartment.
Though the defective relay cannot be inspected visually, you can simply swap it with the identical horn relay and honk the horn to check if it is working or not.
Corroded Wiring

Being responsible for receiving the electrical charge, corroded wiring can impair the proper functioning of the automotive horn and cause it to suddenly stop working. Thus, you can replace or clean the wire to check if the horn is still working or not.
Expanded Airbags
A malfunctioned car horn can also be caused due to expended airbags in car. The airbags expand sometimes and interfere with the horn operation, causing it to fail. However, if there is something wrong with the airbags, then you can easily detect it with the airbag dashboard light. If you find any issue with your car’s airbag, then get it changed on an immediate basis. You can easily buy car airbags and other car parts for sale in the UAE at different prices.
Defective Horn Switch
A horn switch is usually placed on the steering wheel. This contact is responsible for activating the horn when the driver presses the steering wheel. Therefore, if it is defective, it is even necessary to remove the steering wheel to repair it.
