Ferrari Mailing List: Horn problem persists, this is annoying.

[Michel Savard (mysavard]

I took the condenser out, clean it real good (saw a video on youtube). The 
sound is a bit clearer. But …….

I sit in the car and push the horn button: Good sound.
I put the key in, turn it just at “ON” and push the horn button: Good sound.
I turn the engine on, wait one minute, push the horn button: Good sound.
I drive away, 7-8 minutes later while on the highway, I push the horn button: 
No sound at all.
No sound at all for the rest of my sunday drive (35 minutes) celebrating a 
Ferrari win in Monaco.

I get back home, parked  the car, push the horn button, still no sound.
Turn off really hot engine, take the key out, push the horn and beautiful sound 
comes out right away. 

What’s going on ?

I haven’t checked the relay yet as one suggested.
