If you have flushed the heater, I assume you did this by removing the hoses from the thermostat housing. If there's still no heat, check
1. the thermostat is actually present. If not, put one in. If the radiator core is in bad shape, or blocked, replace the radiator.
2. the thermostat is not jammed open. If so, replace it and use a new gasket under the cap.
3. Verify that the water pump belt is not loose.
4. Remove some dash panels to get access to the heater core valve. Check that the valve is actually turning when you adjust the dash control.
