Horn doesn't work

Try connecting power directly to the horn and see if it goes off. If not, it would seem it needs replacing. If it works, maybe the horn switch on your steering wheel is broken. A simple process of elimination.

when pushing on the horn pad you may hear a click noise this tells you the circuit is good from the horn pad to the horn relay and out to the horn. find the horn and check for power at the horn terminal when the horn pad is pushed. if it lights up then replace the horn. if it doesn`t then you will have to check for a wire problem from the horn back to the relay. but horns are usually the problem.

Check the horn ground. By pass the relay and feed the horn at the relay terminal. Could be a bad wire from the relay to the horn.

You can replace the horn. Check to see if the wires connected to the horn have power. Check with a test light. If power is present then the horns are bad.

the battery may be faulty,just because the lights & horn work doesn't mean that the battery is enough power to start the engine the battery may have a weak sell that breaks down when you engage the starter try turning the headlights on & then try to start the engine & see how dull the headlights become,if they almost go out the battery is very low or faulty......hope this helps......cheers.

There will only be one fuse for the horn. Find and check the horn relay. If that works check the wiring and the horn switch..

Check that the horn itself is not worn out. If it's not sounding when grounding out, or it has a history of being faint in volume, then replace the horn.

Horns do go bad over time due to atmospheric moisture causing the contacts to corrode.

fit a new one ,end of story

The horn probably got water in it and this caused it to rust around the electro-magnet inside causing it to seize up. Replace the horn.
