If it isn't blowing air our of the vents, check the fuses in the fuse panel. If the fuses check out of, you will need to check for power at the blower motor. You can do this with a 12 volt test light that avaible at any parts store. Check the wires that attach to the motor. If you have power, your motor is bad and needs to be replaced. If you have no power, you have a short in the circuit. Check the resistor in the blower housing. I've seen a lot of these go bad recently.
