If / when you replace the horn, here is a little tip.
When I replaced my lights, I had to pull the horn. The horn is mounted with a small nut (10mm if I recall) on the inside of the mounting bracket with virtually no clearance. Trying to remove it with a wrench without dropping it was a pain. Finding it in a gravel driveway afterwards was tedious. When reinstalling, I realized that the bracket is sufficiently flimsy so as to allow it to be bent inwards towards the engine compartment. I was able to get my fat fingers in there with no problem once it was bent. Seems disgustingly obvious in hindsight but live and learn.
