How to repair a horn?

[adil]

Is it possible to repair the horn of a car without under supervision of any expert?

The horn completely stopped or the horn volume is really low?

 

If the volume is low, then you have to open the hood and check for the horn connector near the radiator and fix the connection problem. If the horn is not working completely, it means the fuse is gone. You need to fix the fuse.

Good advice lonely. I had this problem two years ago - my horn completely start working although I rarely use it. I had to fix it at a car repair shop.
