don't work? why not

It's not the horn itself as i've tried this. May be a fuse? but i think they are all ok. any other symptons??

 

check if your brake lights still work. if not, then it's the fuse as it controls the brakes & horn. 20 Amp inside the car .. 3rd from the end on the middle row as you look at it next to the pedals!

cheers
