Locate the 2 hoses/pipes going to the heater core. Going from engine compartment through firewall. Run engine to normal operating temp. Then turn blower on full in hot position and check both of the pipes/hoses are getting hot to the touch. If not check/replace thermostat and flush coolant system. If they are getting hot. Let me know and we will got to next test?
