What are the reasons for the Octavia's horn not working?

Octavia's horn not working reasons are: 1. The horn fuse is blown; 2. The horn relay is not engaging; 3. The steering wheel clock spring is broken; 4. The horn switch circuit contacts are not properly connected. The horn is the audio signal device of a car. During driving, the driver uses it to issue necessary sound signals according to needs and regulations, warning pedestrians and alerting other vehicles to ensure traffic safety, as well as for urging and signaling. The Skoda Octavia is the first sedan under the SAIC Skoda brand, with body dimensions of 4572mm in length, 1769mm in width, and 1462mm in height, and a wheelbase of 2578mm. In terms of appearance, the Octavia adopts Skoda's new family design language, showcasing a simple, fashionable, and elegant styling, with exquisite details adding the finishing touches.

I've been driving my Octavia for several years and also encountered the sudden horn failure. The common causes usually boil down to these points: Most likely it's the broken clock spring (that small component connecting steering wheel buttons) inside the steering wheel - replacing it solved my problem last time. Secondly, it could be a blown fuse - just find that 15A mini fuse in the black box near your left knee in driver's seat and replace it. The horn itself might be faulty too - if you don't hear the honking sound when pressing it in garage, it's probably broken. Wiring connection issues or relay failures are also quite common. I suggest first checking the fuse and clock spring yourself. If still unresolved, just spend about 100 yuan at a repair shop to fix it - safety comes first.

Last time at the repair shop, I helped a friend fix an Octavia horn malfunction. The typical causes fall into a few categories: First, mechanical issues, such as worn or stuck steering wheel contacts—just disassemble the steering wheel and clean the metal plates. Second, electrical problems, with blown fuses being the most common, especially during short circuits on rainy days. Then there's the horn itself reaching the end of its lifespan; I've seen cases where the sealing ring aged and let water in. Lastly, interference from aftermarket installations, like accidentally disturbing wiring when installing a dashcam. In actual repairs, 80% of the issues are related to contacts or fuses, which can be diagnosed by checking circuit continuity with a multimeter. It's advised not to tamper with the airbag module yourself.

Several Octavias in our neighborhood have experienced horn issues. Old Zhang's car suddenly stopped working after a car wash, and upon disassembly, it was found that the steering wheel contacts had oxidized. Mine failed after rain, and the problem was traced to rusted connectors at the base of the horn. Another neighbor's car had a signal failure due to a modified center console. Essentially, the faults fall into three categories: signal transmission interruption (clock spring/contacts), power supply issues (fuses/relays), and terminal faults (horn failure). Problems are most common in winter, especially after car washes when accumulated water freezes and causes short circuits. In such cases, avoid slamming the horn repeatedly to prevent relay burnout.
