Check voltage at horn end. If that does not work check the fuses. Check both sides of the fuse as to check all good

And what landrover do you have?
What makes you think it’s the switch?

91 defender 90. Power at the fuse, no power at the horn.. missing link must be the switch?

so replaced the horn.. still nothing. Opened up steering column and found the main connector to the indicator stalk with horn etc.. no power there on the purple black wire which I’m assuming is the horn cable as same at horn and at the horn fuse (still has 12v at that point)
Any ideas? Break in wire? Cheers

Is there a horn relay? One of the five relays below the fuses??

Did you test the old horn or the new one? Is there 12v at the connector when you press the horn button?

Horn should not be on a relay.

Logic tell me to connect a wire from the horn button, out the window, over the wing and to the horn.
If it goes "beep" then you have a break in the wire, if it goes 'clack' then you don't have enough current either (a) arriving at the horn or (b) going to earth (which needs a clean) or (c) the horn is faulty (they do rust up and die).

If (a) connect a wire directly from the battery to the horn switch.
If that works ... if not get a new switch.
(b) clean the earth, ie where the horn attaches
(c) get a new horn.

Do not be tempted to get a dual tone air horn or some other/similar, overly loud, monstrosity.
