The rear fog light in my BMW E46 2001 is broken.
Obviously, I first tried replacing the bulb itself, but the old bulb was still fine. I tried with a new bulb anyway, but the light didn't work.
I visually checked the wiring in the trunk and especially the connection from the trunk to the car, and everything seemed fine. The housing unit is completely clean, by the way.
When I turn on the light in the car, the dash indicator does come, but the light itself does not. I'm not sure where to look anymore, since the bulb and the wiring seem to be the two major culprits.
I looked on the internet for answers, but I always come across the same answer: check the wiring. Which I already did. At least visually.
Is there anything else I should check? Any particular fuses (I looked on the diagram and I can't find any fuses specifically related to the rear fog light), or other weak spots in the wiring? Any other suggestions are obviously welcome as well.
