Horn wiring
 

Hi, I have a Mazda 323 (2001) and the horn soused like
It had larengitys until it eventually stopped working. So I disconnected the horn and tested it on a 12 volt battery and it worked.

The horn relay clicks when the horn is pressed on the steering wheel.

Any advice would be greatful.

Thanks

Maybe the horn had a bad ground connection. Maybe the relay is on its way out or the wiring from the battery to the relay to the horn has increased resistance. I would check in the same order.
