    If the furnace heating up? If so the blower motor or blower motor circuit is at fault.

    If the blower is running and no air is coming out the registers it might be a belt drive blower and the belt is broked or slipping. A very dirty air filter will also cause this problem. A dirty A/C coil will also cause this problem. Anything that restricts air movement can cause this.
