2001 Headlight problem

driving home and headlights start to go off/on, now they only go on for 1 sec every 15 or so and getting worse. There is a buzzing/clicking noise coming from behind both headlamps all the time, cant find relay, also dome light blinks constantly. Anyone have a clue before I start tearing things apart? thanks

the module behind the drivers kickplate did not fix my problem. I sent it out to be scanned and repaired. I was told nothing wrong and charged $50 for scan and $17 by the post office. If you find an answer to your problem please help me with mine.thanks
