I just acquired a 2001, 85K/mi.-young C70 Cabrio and have been steadily "restoring" it. Out of nowhere my courtesy and map lights went out leaving me with the annoying and continuous chime. I traced the issue to a fuse (#15) and replaced it. It worked for all of 10 minutes. When I attempted to replace it again the fuse slot just sparks and blows the fuse immediately. It would seem that there is a short somewhere. Anyone out there have this problem - and more importantly resolved it? Any clues or spots to look? Are there any easy sure fire ways to find the culprit? Any help is greatly appreciated. I really love this car and am anxious to get it right. Thanks, Marc
