Answers :

Your run temperature is within spec. Your problem possibly is in the heater core itself.

Check the hoses going to the heater core and make sure both are warm when the car in at run temperature and the heat is turned on.

If one is cold and other warm you have a flow problem in the heater core that must be corrected.
