My rear fog light came on whilst driving with lights on and noticed that the fog light light had come on the dash. Tried to turn off but couldn't, so stopped and checked of fog light was acutally on at the rear of the car which is was. Tried everything I could,but still can't get it to switch off. Bulb has had to be taken out for now but need to know what to do to fix the problem. Hope you can help.
