Hi dear sorry for the problem
This could be caused by these five things; Low level of water, The blend door is not fully closed, thermostat not opening up, Heater control valve is bad, Bad heater core. Make sure the radiator is full of water. Change the thermostat and flush the radiator. Then check or remove the heater control valve. Last replace the heater core. Good Luck!!!
