Hi
Thanks for the advice but after been nagged by my wife to take the car in to dealers in they did a test and said their was a leak from the windscreen into the dashboard where water was dripping and had collated under the dashboard. They took off the windscreen and dried out the water, then changed the windscreen seal and bonded it. All was fine and well and they put back the old relay. I have a relay spare as I am stuck with it now. Their conclusion was their was water dripping onto the curcuit of the headlight which was cusing a short all the way to the fusebox and the headlights, so if this happens to anyone it could be this rather than the relay. once again thanks
