I noticed that my front left low beam light was not working when I pulled in to my parking lot today. There's an independent shop nearby who does easy repair work, like change light bulbs. I went there over lunch. They put in a new bulb, but it did not work. We did a quick inspection of the old bulb, and it looked intact. Looking more, we noticed that neither the running light nor the low beam was working. However, the high beam does work. What is the most likely cause of this? I do need to get my car in for a recall issue (airbag), so will have the dealer look at this. Just curious what you all think it could be. Thank you!
