I'm talking about the incandescent light bulbs in the overhead reading lights, and the clear/red lights in the door (to warn rear approaching cars the door is open). Basically all the interior lights not lid when I opened my door. I have checked my fuse box and all fuses seem not blown. But I can turn on the overhead reading lights manually. I suspect could be one a relay switch control the lights is faulty. Can anyone kind enough to tell me the relay switch location inside my Porsche 996 cabriolet (2004 model). Thank you folks.
