I had the same problem in my 1992 Cougar LS. I simply replaced the headlamp switch. It cost me $12 and took me about an hour to do it. The switch is to the left of the steering wheel. You will need to take the dash apart, and replace the switch. It was the first repair I ever did to any car, and it was so simple and cheap, I'm going to keep fixing things myself. ! -Cricket
