My 1992 Acura Integra with a b16a3 is haveing a weird headlight problem. When i turn on the headlight nothing happens untill i turn on the "high beam/fog light" switch then it turnes on the headlight but not the middle lights. the high beam/fog lights dont work. but the head lights only work when i switch on the high beam/fog light swiutch. What is causeing this?
