Hopefully i can help..


The horn itself will be usually be behind the bumper - often you need to get under the vehicle and look straight up at around the passenger side is where they often mount these and then see what the connection is like to it..sometimes being prone to outside elements bad contacts to the horn itself wouldn't be unusual/the horn body itself is the earth so check that too its mounting point - so maybe try and inspect that..if you have voltage meter or test light even check there is actually voltage reaching the horn itself when you press the horn in the the van - if its sending a feed to the horn then you can asume the contacts on the steering wheel are ok.the fuse obviously as already checked/relay in the engine compartment if i recall and the rest of the wiring to the horn itself..if a voltage feed is getting to it each tie you press the horn in the van - then the horn is pretty much suspect and needs replaced..I do hope this helps

hello Robert i did'nt even know there was a relay in the engine compartment how do i locate it

are you still there Robert.

Robert, UK Qualified Car Technician replied 2 years ago.



Ok.. You need to find the engine bay fuse panel the relays will be situated in there..unfortunatly i can't seem to find a specific diagram for that age of van but usually you can tell which relay it is unless printed on the lid - by listening for it to click when the horn is depressed in the van once you know which one - then you can pull it and swap it over with another of the relay of the same - and then retest it that way if it still doesnt work then its pretty much the horn itself..but try locating the horn body and see if it does get a feed - if it does each time the horn is pressed then that rules out the feed circuit being at fault and the horn itself being at fault..I do hope this helps
