My car failed inspection today for a non-working right front side marker bulb of all things. The mechanic said it is NOT the bulb or fuse and recommended taking it to the dealer to find the problem.I went to the dealer today and they said bring it back next week because they might need the car all day. What else can it possibly be and will it be a major repair? After all, we are talking about a light bulb !!!

I am SO frustrated. Thank you.
