My horn quit - not the fuse.

[m3ga_band_g33k]

Hello everyone!

I have a 2008 Yaris Hatchback and the horn has more or less quit working. 95% of the time it doesn't work, maybe once or twice every other week or so I can make it sound, and even then it sounds really weak and kind of peters out after a few seconds if I hold the horn down. The fuse is fine, what else should I check? I was in an accident back in February that may have knocked something loose, the horn quit about a month after this accident.

Any ideas would be great.

Thanks!
