I have an issue with my interior lights on an fn2 if anyone has experienced the same. The other day I changed all of my interior bulbs to LED. As I was installing the rear one I noticed a small spark and all of my other lights stopped working. I've pretty much worked my way through the entire interior fuse box (including) the ones for the interior lights but can't see any blown. I've also changed several for new ones but still no joy. HELP!
