I have spent the last hour or so going through the archives looking for possible reasons the interior lights refuse to function on my 528e. Rob Anderson gave some great advice, and I am beginning to wonder if perhaps a dead relay may be my problem and not a faulty dash switch.
Is there an interior light relay? If so..... Where is it? If anybody knows and has a digital camera, would you take a picture of it so I can find mine? Anybody know how to test it with a standard issue multimeter and a test light?
