Mazda Horn Is Not Working

A couple things can go wrong with the horn in your Mazda - most commonly, it may be blowing in a lower tone, or none at all. Either way, it is likely that you can fix the horn yourself. Here are the steps needed to fix your Mazda’s horn.

Mazda Horn

Low Volume

  1. Open the hood on your vehicle and ask someone to press the horn for you. If the horn sounds, but is low, then one or more of the horns on your vehicle have stopped working.
  2. Look behind the radiator core support and locate the horn.
  3. There will be a wire connector that attaches to the horn. Remove that connector by pressing down on the lower end of it and pulling the wiring out. It is like a fuse. Take the mounting bolt and lugs off. Clean the connection components and then reconnect them. Try the horn again to see if this resolves the problem.
  4. Replace the horn if cleaning does not work.

No Horn

  1. Open the fuse box and check the fuse for the horn. Your owner’s manual will tell you where the fuse is located.
  2. Use needle nose pliers to take the fuse out of the box. If you can see that the metal strip inside it has broken, then the fuse is no good.
  3. Replace the bad fuse and try the horn again.
  4. If the fuse is not bad, but the horn still does not work, check the dashboard to see if the airbag light is lit up. An airbag problem can cause the horn to stop working. If it has expanded, it can interfere with the clock spring that provides power to the horn.
  5. Replace the horn if the airbag light is not on and the fuse is not bad.

Note: If you find that you need to remove the airbag, you must take your vehicle to your local dealership since that is a part that cannot be removed or fixed by anyone other than professional technicians.
