I have a heating problem with my truck I have replaced the thermostat with OEM 192 degree and removed all the air from the system and my truck runs and low temp in between just inder half way to the 210 degree mark while driveing at freeway speed. I have no antifreeze order coming from the heater core and no leakage in the system anywhere but when I turn the heater on high it blows cold air but whenthe at fan speed 3 it barely blows warm air what can I do to fix this? been cold in MN

Feel the heater hoses are they hot? If yes then blend door problem. An accuator is not closing off core for heat. How is heat at low speed ? You could try the cardboard in front of rad.

heat at low speed does esnd out hot air but the speed is so slow that is doesnt warm up the cab. I am unsure if the hoses are hot will have to check.
