Heater blows cold air. I have replaced the thermostat. The blower motor works and the heater controls seem to be working. Where do I go from here? Thanks Alan

Check to see if both hoses are hot under the hood first when warmed up. If they are one of your actuators may not be working, this can be eitehr electrically, vacuum or mechanically controlled. I'll send a generic pic along they are under the dash.
