Thanks everyone for your help. I turned the steering wheel back and forward a few times and it appears to be working now...I am thinking its a dodgy connection at the steering wheel. I shall take it for its MOT and if it fails on anything ( the forever pessimist) I will get the garage to do the necessary on the horn. If it passes I might take a stab at doing it myself! The prospect of breaking my nose brings tears to my eyes.....
I am feeling a bit brave since I renewed my house kitchen tap with no disasters
