Try honking the horn with the cover open. If you hear a sound, but much weaker than usual, it suggests that that some tubes are impaired but some still work. in fact, on your Ford Mustang there are several trumpets that carry sound.
Step two, try to track down the horn. You will find it near the radiator at the front of your car, near the grille. The grille is the small grille at the front of vehicles that allows air to enter while protecting the parts of your Ford Mustang.

Once the horn is identified, we will try to disconnect and reconnect the connecting wires in order to perform a new test. To do this, take the two connected wires, pull them out by their ends towards you. There should also be a horn fixing bolt that you need to unscrew. Then clean it all up with a brush or something, then reconnect it all. Try honking your horn again. Does it work?

You should also take a look in your vehicle owner’s manual for the fuse references of the horn fuse that you must identify precisely.
Once the fuse is identified, you can remove it using a pair of pliers. To verify if it is burned, examine the metal part. If this one is blown, your fuse has blown on your Ford Mustang. It must therefore be replaced. If it looks new, it should not be questioned.
You can find this fuse in any car shop or garage. Test the horn again after the fuse has been changed. Is your horn working again? Congratulations! If this still doesn’t work for your Ford Mustang, check your dashboard and specifically your airbag indicator light. If this one is on, there may be a link. Actually, it can have an impact on the rotating switch, a part that acts as a relay between the steering wheel and the horn. However, for an airbag indicator problem on your Ford Mustang, it is recommended to go to a professional as it is more challenging to manage alone.

Conclusion
