2004 307 1.4 hdi horn problem

My horn was not working, I guess it was this, I removed it as my master described it, cleaned it, put it on. My leg doesn't work again. I checked the fuse, when I press the horn, the relay sounds like a click, but there is no sound in the horn. Either my horn cortted, or there is something in the installation. When I connect the bulb to the cables going to the horn, the horn does not work when you press the horn because ..

What do you think?
