2005 645ci low/high beam Headlight problem
I had moisture in my driver headlight and my headlight finally died. I assumed it was just the bulb so replaced it and still no light. The angel eyes and "flash pass" light both work. Next I replaced the xenon control unit and no light. All fuses seem to be fine. I decided to swap the whole driver side headlight assembly with the passenger one and boom let there be light. Both headlight work perfect in the passenger headlight harness but neither work on the driver side harness. Any advice would be very much appreciated!! Thanks.
