My A/C works, fans work on all speed settings, car does not overheat, blower motor works... But I have no heat. Just blows cold air.

Coolant level is okay, heater hoses get hot too. Just no heat gets into the car.

Yep, this means the temperature blend door actuator is not working, I would change it out.
