I quess is that the spring plunger that is behind your horn button is defective. Remove the steering wheel to replace it.
Run a direct wire from the battery to the horn, if it works the problem is in the horn button or the fuse.

If everything checks out, replace the horn.

If you have a Eurosport version simply gently pry around the edge of the button with your fingers and it will lift off. If you have the standard version the horn button is held on with screws through the spokes from the back side of the steering wheel.
