If the blower works check for coolant in the cooling system. Test operation of thermostat. Check heater control valve for proper operation if equipped. Pressure test cooling system to ensure system holds pressure (this will help you identify a leak, if any. If car does not over heat and cooling system is in good working order, then the heater core is clogged.
If the blower does not work Check fuse, relay, wiring for short to ground, apply direct battery voltage to blower motor. If blower motor turns on and fuse/relay and wiring are ok replace the switch.
