Check the hoses on the heater core once the vehicle has reached operating temp. if one is hot and the other cold or just warm heater core may be plugged and may need to be flushed or replace. Also make sure system is purged of air

Fan is blowing but no heat is coming out

check the heater core and change the thermostat

if the car is over heating then the heater core is bad if not then it is definitely the thermostat

if it still continues then check the heat control panel
