I hate to revive an old topic but I need assistance. I've got an '04 Mini Cooper where the moon roof leaked into the drivers side floor. I've reconnected the tube as this thread suggests, dried out the floor and re-sealed everything. Initially all of the electronis worked fine. Now however, my tach with all of the components on it, no longer works and neither does my AC. Everything else is OK. The car runs, drives, etc. Brake lights and turn signals work although you can't tell from the inside. I removed the fusebox and cleaned the connections. All the fuses are OK. The one problem seems to be the Tyco brand connector with about 20 wire running in and out of it that was totally submerged below the fuse box. It's got a white piece that slides over to open it up. Blue copper crap was coming out of it and when I mess with it, some stuff comes back and some does not. I'm being told by a garage that I'll probably need a new BCM but that doesn't make sense to me. It's on the other (dry) side of the car. Any thoughts as to what to try next? Any help would be greatly appreciated. Thanks!
