Mine does the same thing. With the climate control in auto when you first turn the ignition key on the climate control comes on and sees a big difference in the temperature inside your truck and the temperature that you want it to get to so it goes into a maximum cooling mode which is high fan speed and defrost vent outlet position. I find it rather annoying when it is in this mode so I just raise the temperature set point up a couple of degrees above the actual temperature so that the fan slows down and it starts blowing air out the front dash vents instead of the defrost vents. Once it swings over I lower the climate control temperature set point and it will stay blowing out the front dash vents at a slower fan speed.
