horn blows constantly when stated; need to disconnect to fix; help needed.

Remove the horn pad and see if it stops.

When my horn pad disintegrated, pieces of it were grounding out causing my horn to go off. I also had issues with the screws coming loose on the horn pad and also grounding out.

Same happened to me.
The slipring behind the steering wheel was worn out.
Cheap part and easy fix.

Umm... don't get stuck in traffic behind any Hell's Angels!

Make your brakes louder LOL

Seriously, it's a wiring short behind your wheel.
