I came home and tried to turn my A/C on the unit came on but nothing comes out the vents is it the blower motor if so, if we replace it how much would it cost?

Did outside unit come on and not the inside unit? Have you checked your filters. If it's the furnace blower motor you are most likely looking between 100 and 200 dollars for just the motor. Could be more or less, but that's a ballpark.
