I have a 2003 C230 Kompressor with 165 000 km, and my horn stopped working a few weeks ago. The relays are okay all the fuses are okay no error messeges on the dash so i don't know were the problem is.. Has anyone had this problem and what can it be?

Thanks:

 

I have a c320 with similar problem. One of the (two) horns stopped working. Is there a way of fixing it quickly or is the $$$ route the best option?

 

I tested both horns today with my booster pack and they work perfectly... I changed the relay for the horn, but my horn doesn't work when i push the horn.
I think there is some kind of electrical or wiring problem.

Does anyone know what it can be?

Thanks:
