Is this a 4.9 car, or northstar? Grasp the hoses that feed the heater core, they are behind the passenger front strut tower. Are they hot?, one will be cooler than the other to show heat is being exchanged. If they are not too hot, then the core might be plugged. If they are hot, check behind the glove box, there is a linkage rod. When you change temperature, this rod should move. You can also disconnect the rod from the white clip and move the blend door yourself. If it does not move when temp is changed, the actuator may be faulty.
