Greetings all, 2004 645ci. The low beam cap came off of passenger side headlight some time ago and moisture collected in housing. There is a green light blinking on headlight control switch and the neither headlight will auto-level. I have tested the bulb and ignitor, no problems. Im thinking the ballast got wet and died on me but, if the headlight control module died as well. Why would it effect the drivers side. Also, whats the difference between the control module on the side of the headlight and, the one in the footwell???.....PLEASE HELP.
