Check the operation of the blend door on the passenger side below the glovebox. Verify the HVAC controller is sending commands to the blen door actuator. If the coolant level is correct, the thermostat opens and closes as it should, and the blend door works, the heater core could have debris. Does it have Dex-Cool that is older than 3 years in it?
