I have an 05 mini cooper S convertible that I just got out of winter storage. The battery was unhooked during the winter. The convertible top opens to its first step ("sunroof"), but is completely dead to opening after that. No sound at all. Also, the back side windows don't go up or down. I have a feeling that it might be a fuse that got blown when disconnecting or connecting the battery. Any other ideas? I've tried opening and closing the front windows, which didn't do anything.
