Ok, assuming you are correct, it could be a clogged heater core, blend door motor not changing the door. Have them checked

Is the blend door under the dash? How do you check it?

Yes, it is an electric motor and due to low voltage, it is monitored from a scan tool which can force the door to move back and forth.

TEMP. ACTUATOR POTENTIOMETER

INSPECTION (FRONT)

Temperature control actuator is installed in the heater unit case. The control switches and the vent duct switch will operate actuator to regulate the temperature and discharge air.
Verify that the temp actuator operates to the warm position when connecting 12 V to the terminal 1 and grounding terminal 3.
Verify that the temp actuator operates to the cool p0sition when connecting in the reverse.
