Does the fan operate on the heat side? If yes the problem is probably in the selector door for heat/AC.
If the fan doesn't operate at all check the connector for 12 volts while on high speed. If you have power but no fan then it is likely the blower. They are not real fun to change, you can get the repair info on the www. Eautorepair. Net site.
