Best answer (according to cold in Utah)
cold in Utah from United States 11 years ago
I figured out it was the thermostat. The upper house was cold, thus the thermostat was shut,, The noise that sounded like a blower,, was the fan on the truck. Turns out it is a very intelligent system , The truck has a brain, that when the thermostat is stuck and senses the truck engine is hot,,, it does all it can to put all efforts to cool the engine. Thus it increase fan speed to a very high speed and shuts down all demands to the cab,,. It shuts down the defrost to conserve energy and to protect the engine... a good thing... I learned a lot and I hope this helps the next person... I am used to old school V8's that you tune by ear. This was a real cool lesson, no pun intended :). I feel very good about the technology our cars have built in them. Mahalo,, Thank you
