Did you check for a heater control valve if not check if it has one and start there if not-backflush the heater core both ways-get a garden hose and do the job right-if it continues -replace the heater core

Do you have a repair manual if so check if it has a heater control valve something similar like below.
Test it if it works replace the heater core
