Recently my 1997 GM battery went dead. I found that if I pulled the number 8 fuse the drain would stop. That fuse operates, door locks, interior lights, etc. Anyone have any suggestions. I pulled the door panel and unplugged all the door electical connections and that didn't help. I wonder if those mysterious courtesy lights are putting out a little juice after they go out. The test light flickers or pluses when checking the drain. Thanks
