too bad people that actually know what it is dont speak up...ive had this problem forever too.. after awhile it just stops..but now my dic doesnt light up at all and my blower resistor went out..only works on high. but the dic is still working i can tell because when light is on it you can still see it, it just doesnt light up. but when i turn on the blower to high it will stop working, it will just keep going on and off yet all my headlights will work
