kind of confusing reading that.... but I'm going to assume the modes work correctly. Temp on full hot, blower on high there should be a noticable difference in heater hose temps.... think of it as a mini radiator with one hose being the inlet, and the other the outlet. If both hoses are the same hot temp, I'd suspect the heater core is restricted. Another thing you can check is the blend door motor. This motor is located under the heater-A/C housing directly over the floor panel transmission tunnel, and can be removed from the passenger compartment without instrument panel or heater-A/C housing removal. You can leave it plugged in while it's removed and turn the temp knob and see if it moves. It will also allow you to check the door sweep manually.
