Is the dash clock connected to the A/C in some weird way? The only solid evidence I have is that the compressor in my 7 started failing and whenever it blew the fuse for it, my dash clock would go out. Also all of the 7 owners near me without A/C in their car do not have working dash clocks, and the only ones that have a clock... have working A/C. Just a thought, but if there is a diagram that someone wouldn't mind pointing my dumb face to that would be the best!
