I know the fuse and relay are under the bonnet. The fuse is OK but I can't budge the relay..

Anyway, is the ECM in the passenger footwell involved at all with the horn?

I know that the ECM needs fixing so perhaps this is causing the horn problems (as it did with the wipers!)?

Otherwise, I can just buy a new horn/pair of horns !
