Hi, I used my horn 5 times in a row last week & its not worked since, I am sure its fuse or something simple, I would like to start at the fuse but I got no handbook with it, there is a box in the engine & 1 under the dash, I have looked on the internet for fuse box diagrams that claim to be for the 2010 doblo on but they are not as the fuse arragement is so different, & the numbers on that don't match, does anyone have the correct diagram for 2011 Doblo cargo van, or even tell me exactly which one is the horn fuse. I even have a spare horn which has a better sound than this one but the connection is different again, which I can sort out once I have established that its not fuse or wiring.
