Recently, I had a body shop repair my car and over the time they had the car, the battery got drained for some reason and I experienced a few electrical issues afterwards (outside temp not reading, trunk not opening, etc). Now everything is solved but the passenger side low beam.
First I thought it was the bulb but I swapped the bulbs side to side today and the result is the same.
Where do I start? I would love to fix it but just not sure where to start looking,
Could it be just a bad battery?
Thanks,
I am having a similar issue. My passenger-side headlight is out. Not just the actual forward projecting Xenon, but the entire unit. Halo Eyes, high-beams and low-beams are out and the whole corner of the car is dark at night minus the right blinker should I activate the turn signal switch motioning a right turn. The fog lights operate normally. Very first time I have seen condensation inside of the the headlight assembly too. I am sure it's related but not sure why or how. I have disconnected my negative post for a while to clear the computers, but maybe not for long enough. Got a car wash with undercarriage jet-spray done almost 2 weeks ago but this started yesterday so I don't think that's the reason. Would my alternator be able to short my headlight assembly control unit? If so, would simply replacing the control unit resolve the issue?

Could it be the need of an alternator and/or battery replacement? The lights worked perfectly until I had a power glitch while driving on a long downhill behind a slow driving Smartphone user who felt it ever so amusing to continuously tap her brakes or purely ride them all together. These big-boy cars don't like SLOW. Coasting now dims my digital display as well... Any suggestions are greatly appreciated ahead of time. Any Indie-Shop here in the Atlanta Metro with a quick-fix... HELP!!!
