I've read a few posts on various sites giving advice about accessing the horn on Boxer and Ducato motorhomes. All this stuff about crawling underneath and scraping your arms to shreds is utter rubbish. The horn on my 2003 Peugeot Boxer (Ducato is the same) suddenly died, I checked the right fuse, it was fine. Easy access to the horn is this: take out the 4 x 10mm hex screws on top that hold the front grill panel in place, gently pull the panel upwards to remove it...put it somewhere safe where it won't get stood on. Use the same 10mm spanner or socket to remove the two 10mm hex screws that secure the headlamp unit, there is also a ball and socket fixing to the right hand side...give it a good yank and the whole headlamp assembly comes away. There is the horn looking straight at you! The 2 terminals looked a bit powdery so I wire brushed and sand papered them. I reconnected, smeared a little Vaseline around the terminals to prevent further corrosion, I gave the horn a push and YABADABBDOOO I have my horn back! I also tweaked the little Philips screw on the horn body and got a louder clearer sound. Took me all of 15 minutes. Good luck, hope I've been helpful!
