Car Horn Not Working: Causes
A dead horn is a small fault with a safety (and roadworthy) impact. A Cranbourne West specialist explains.
What it usually means
A horn that’s stopped working is usually a blown fuse, a failed horn unit, a broken clock-spring in the steering wheel (the ribbon that also feeds the airbag — often with an airbag light), or corroded wiring/relay.
A dead horn plus an airbag light points to the clock-spring.
What you should do
Get it fixed — a working horn is a legal requirement and a roadworthy item, and if the clock-spring is the cause, the airbag circuit needs attention too.
We test the fuse, relay, horn and clock-spring to find the fault.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.

Car Horn Not Working: Causes — FAQ
Usually a fuse, the horn unit, the steering clock-spring, or wiring/relay corrosion.
Yes — a working horn is required. It’s usually a quick fix once found.
The clock-spring feeds both the horn and airbag — a break affects both and needs prompt attention.
We test fuse, relay, the horn itself and the clock-spring in sequence.
