Neither low beam works on my 323i. I hate to buy a new xenon bulb and find out that isn't the problem.
How can I troubleshoot the lights? I inherited the car from my daughter when the engine overheated.
She doesn't know when the lights failed, I think she'd been driving with high beams, so I don't know
the circumstances of the lights failing. What checks can I do to the lights, ballast, igniter, LCM?
I looked at the fuses in the fuse box and no blown fuses.
