Horn is not working

Informational, low priority

car horn silent · no sound when pressing horn

Symptom description

Pressing the horn button produces no sound at all, or only a weak, distorted sound.

Common causes

  • A blown horn fuse
  • A faulty horn relay
  • A worn clock spring (the coiled cable behind the steering wheel that carries the horn signal)
  • A failed horn unit itself

What to check

Check the horn fuse first (see the owner's manual for its location) - it is the cheapest and quickest thing to rule out.

Can you keep driving?

Safe to drive, but fix it promptly - the horn is an important safety tool for avoiding collisions.
