Identified Causes
Blown Horn Fuse
70%The fuse protecting the horn circuit may have blown due to an electrical surge or short. This is a common and relatively easy fix.
Faulty Horn Relay
60%The horn relay acts as a switch for the horn circuit. If it fails, it will prevent power from reaching the horn itself.
Defective Horn Button/Clock Spring
50%The horn button on the steering wheel or the clock spring (a coiled electrical connector behind the steering wheel) could be damaged or worn out, preventing the horn from being activated.
Failed Horn Unit
40%The horn itself, which is an electrical component that produces the sound, may have failed due to corrosion, internal damage, or simply reaching the end of its lifespan.
