Q: Horn starts blowing by itself

asked by on

I can push the horn button and it will blow. Whiting a few seconds it starts blowing.

My car has 15100 miles.

The most common cause of the horn going off all by itself is the horn buttons inside the steering wheel are shorting out and need to be replaced. They may be heat or cold sensitive when the problem happens/ It is the extreme temperatures that caused the problem and needs horn buttons or assembly to be replaced.
