Have you tried putting a 12 volt feed to them, that would tell you if its the horns or not!

No, put a 12v direct feed to the horns, to double check that your horms actually work

I had the same problem last year in the ML. When I went to check for a voltage and make sure there was a good contact, the terminals on the horns (both) just fell apart. I got 2 new ones from the local factors for +/- £10 ea and it's been fine ever since. They get covered in a lot of crud where they are located, so I'm not totally surprised after a few years they needed doing.
