I have an odd situation. My abs and esp light come on when i turn my headlights on. Not always but lately more often. Sometimes with the headlights off but almost always with them on. I noticed that there is a little light that flashes on my **** that is used to turn the headlights on. It just always flashes. My hazard relay clicks often too. I replaced it and it still makes that buzzing noise off and on. I noticed that buzzing from the relay started when i needed an alignment. Had that done and it went away for about 8 months and started again so i replaced but still buzzes. Had my mass airflow replaced last year too. Any help would be great
