Suggest you recheck the fuses under the dash and in the engine bay ... can't help beyond that. Find a local auto electrician as they are generally mobile and usually cheaper than a garage.

update managed to check fuses to day and found horn switch on sterring wheel faulty and its not making any contact when putting pressure by pulling up the top of the horn cover on stereing wheel then pressing horn it works and sounds im thinking its faulty air bag horn switch contacts dont look to good on sterring wheel either removed it to have a look put it back now nothing any clues it has a multy plex system bsi and ecu onboard hard wired system ive been told .all fuses checked and working even horn worked brefly by pulling up on the top of the horn cover  then pressing horn still with the cover forced up

If it's multiplex then the airbag unit clips on ... two rectangular holes at back of steering wheel and you wiggle a screwdriver around to release it. Disconnect battery and leave it for 15-20 mins for airbag system to discharge though before fiddling.

I'm not sure but you may need a new comm2000 unit ... I don't think the contacts are accessible from memory .. (I had the airbag off a few years ago to replace the airbag squib .. this that fires it).
