The turn signal issue might be the rear lamp holders, check the brown wire for heat/corrosion. The A/C issue is the final stage unit, check this link: http://www.realoem.com/bmw/showparts.do?model=BN53&mospid=47713&btnr=64_0820&hg=64&fg=40
No defrost could be no power or a bad grid, turn it on and attach a meter to the electrical leads at the sides. Right mirror may need a new motor if it is totally dead.
