I replaced my front heater core when it had gone bad. The Rear Heat still worked when the front heat didn't work. When I replaced my heater core the heat worked great. The last two weeks the heat Front and Back is blowing cold I have replaced my coolant The Blend Door I can move Manually and that is not the problem I checked the Front Heater Hoses and Both are hot in and out going The Temperature gauge is within normal range and heats up fine.

Help!!

Good morning,

Make sure your coolant level is correct. A low level will cause this.

Check the thermostat for being stuck open not allowing the coolant to heat up.

Beyond that, the cores could be clogged with dirt and debris. Did you flush the system of all dirt and debris when you replaced the heater core?
