No AC or any air on 2007 328i

I am faced with a ventilation problem. All lights on.... no AC, no defrost, nothin.. After doing some reading I decided that I should replace the final stage resistor on my 328 as this was apparently a common problem.... nope, all lights on, no air blowing at all.... Do i need to replace the blower itself... anyone else have this problem, or am I missing something?:dunno:
