look out the fuses,if they are good then check the blowing motor (blowing fan) connector for current if that is also good then may your blowing motor is faulty.

If you think the blower motor is coming on, if you can hear the fan turning, there may be an air vent door that is not working. you will have to remove the airbox located under dash and check the air door nearest the blower motor. Does air come out of the defroster?
