Horn in Sxara Picasso 1.6

Good afternoon:

as a complete nullity as far as mechanics are concerned, I request help (if someone knows) to change the close of my Xsara Picasso 1.6.-

I had to melt it on the celebration of a friend's wedding.

To demonstrate my knowledge, I indicate that I not only do not know where the horn is, but I do not even know how it is or what appearance has.

If it is very difficult to change it for another or not.

Note: I already changed the fuse, and still does not work.

Thanks anticipated.

I do not know the exact location in this model I think I could carry it behind the lower rejilas of the bumper examine whether they come out the typical form of a horn in how the shell of a snail (+ Ò - so that you understand me and get an idea) in almost all vehicles usually have a spin with patillas (for the current) and a support with a
screw I know this model, I hope I have been helpful in something

Thanks Imoggi, even if you don't believe it, it seems to me that you have helped me a lot.
At least I know what to look for and where.
