Under the bonnet. If location isnt obvious, get someone to press the horn button while you listen for it clicking.

What if it doesn't even make a clicking noise!Does that mean it's something more serious!

If someone can tell you the location of the relay (I can't off the top of my head), check there is power coming to it (when horn is pressed), and check the relay my putting power through it.

Check the earth. Could be self earthed (mounting point acts as earth) or may have a separate wire. If after-market, are they running off the factory button/switch! If possible, try running 12v straight to the horn from the battery to make sure its not the horn itself. A pretty simple way to rule one thing out.

Oh yeah, the switch.

Relay should be pretty close to the compressor. Can you track the wires from the compressor, back!

Whoever put the horn in coulda put the relay anywhere, not necesarily (sp) where he should have.It could be anywhere between the compressor and the button.

It just doesn't go, not even clicking when the button pressed.
