2004 Dodge Neon Buzzing sound from turn Signal

I have a buzzing noise that is coming from my turn signal, the turn signal also operates my head lights, high beams & fog lights.

My fog lights are stuck on even if i dont' pull the switch (turn signal) to turn them on. My fog lights are my day time running lights, so evertime i start the car this buzzing noise happens and it only stops when i turn the headlights on.
