I have flushed the radiator, replaced the thermostat and radiator cap. The car does not overheat. Blend door is functioning. But I still don't have heat. Any advise?

Check the heater core ,see if both hoses are hot , take the hoses off at the fire wall and see if water passes through .

With the engine at full operating temp, locate the 2 heater hoses where they go into the firewall and feel them to see if they are both hot to the touch. If they are both hot, the heat in that vehicle is controlled by a blend door that regulates heated air flow. it is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.
