The Dispatch | Expert | Scudo Hub

New member, found the forum whilst searching for wiring diagrams for the Dispatch. Looks a great place, thanks for accepting my registration.

I'm trying to fix up my buddie's 2005 diesel Dispatch at the mo, his horn isn't working.

I replaced the indicator stalk a few weeks ago for him because the indicator switching was intermittently faulty. I bought a mid-price non OEM replacement stalk off ebay & it worked fine once fitted. All functions ok including the horn push switch on the end of the stalk.

Couple of weeks later & he tells me the horn stopped working, after having been fine straight after the stalk replacement, a day or 2 ago.

Looked through all the fuses in the main underbonnet fusebox, they all seem ok. Likewise looked through all fuses in the glovebox panel, again, all ok.

I found a horn mounted to a strut in the passenger side front wheelarch, in front of the wheel. I don't know if this is the standard location for the horn, is it possible this horn is an aftermarket / alarm thing, with the vehicle's 'main' horn being located elsewhere? (somebody told me the 'real' horn is hidden away behind the bumper, below one of the headlights)

I did try to prise off the connector from the horn I did find, to see if I could test the wires for 12V if I pressed the horn button. The connector wouldn't budge - so the metering will have to be done tomorrow now I've found my flat screwdriver to try and persuade the connector off.

Is there a replaceable horn relay on these vehicles, or a non-replaceable relay soldered up inside the guts of the fusebox? Or, is it wired without a relay at all?

Any info / thoughts appreciated. Neil
