SOURCE: heater blower went out?
Either the blower went bad or the heater relay went bad. This does not sound like a heater core problem unless you where smelling a SWEET smell when it was running.

You have one of two situations. One would be a burned out resistor group within the heater box, this controls the voltage flow to the blower motor. The resistor group is a small(about 1 1/2 inches by 3/4 of an inch rectangular plate made of black or biege plastic with four push on connectors. This is usually located on the passenger side under the dash on the heater box. The other possible location is on the passenger side firewall under the hood Look for signs of burnt plastic first, then remove the two mounting screws and look at the inner parts. Most likely you'll find one , or more of the windings are broken. Thank you, Dana

The problem usually stems with the blower motor resistor,high speed by-passes it and there-fore the controller is sending power but the resistor has gone open and the speeds can't be regulated.

Testimonial: "Very helpfull. than you"
Sounds like low speed coil in the Blower Fan resistor block has failed. The Blower Fan Resistor Block is usually located in the air ducting adjacent to the Blower Fan. The Resistor Block consists of 3 or 4 coils of special resistance wire attached to terminals which connect to the wiring that comes from the fan switch and then to the Blower Fan. The block is on the output side of the fan unit so that the airflow from the fan past the coils inside the duct assists in preventing them from overheating and burning out.
Access to the Resistor Block is from under the dash. To replace, remove the multi-pin connector and then undo the screws holding in the block. Check air duct for leaves and dirt which may have caused the coils to fail. .Replacement is the reverse procedure

I think that one still uses cables to control the blend doors and vent doors. Are you sure those are working and/or connected.
Also when you replaced the thermostat and heater core did you bleed the cooling system? With the engine cold remove the radiator cap and let engine idle up to operating temp while keeping the radiator topped off with coolant.
Are the hoses going to the heater core hot?
