Hi guys,

The horn on my 07 Freelander2 TD4 2.2 diesel has stopped working. Checked the fuse and relay (can hear it clicking) and they all seem fine. Any ideas greatly appreciated

If you can hear the horn relay clicking, then it's most likely that both horns have failed.

Had exactly the same problem. Noticed one day horns no longer worked. Took bumper off, checked horns and they had seized. Full continuity on windings but no movement. Replaced with marco tornado air horns. Repositioned so not so prone to water ingress. Brilliantly loud. Scares the s&#t out of people now as so loud. Straight swap, just change the connections to horns.
