Air Blower wont work....

Hello, I have a 2000 Alero and my air blower wont work. I can hear the car make the sounds it usually makes when I turn the air on but nothing comes out. My AC light comes on, but the blower motor wont start blowing air. I have checked all my fuses, all of them are fine. I just had my blower motor replaced last winter. What could be my problem? Thanks

I would pull out the blower motor resistor, bit of a pita to do under the dash there on the passenger side against the firewall, but those always seem to burn out and you end up losing a few settings on the blower speed or you could lose em all.
