The only thing on fuse 63 is the A/C compressor relay. I'd make sure that the system is evacuated and filled to the EXACT weight of R134 it's supposed to have, but I really expect that your compressor is dying. As for the distribution flaps, this is another issue entirely, and you'll have to remove the lower panels to see if the flap motors and arms are broken. Since you're not familiar with the system, and won't have a way to evacuate, vacuum, and recharge with the correct amount anyway, you might want to let a BMW pro deal with this.
