The rear fog lights on my 1999 E46 aren't working. The light on the dash board illuminates, so that rules out the fuse (checked them all anyway).
Checked the bulb and also checked the earth. All are fine. I knew the earth was anyway cos it uses the same one as the reverse lights.
Anything else I should be looking at? Or is it just a case of the wire has broke somewhere and its time to get the multimeter out?
