Just wondering what the normal heat operation would be in the Range Rover sport with Auto selected. Last month when the weather was in the 50s, my heat kicked on and it seemed to be blowing from the dash vents. The last two days it's been in the 30s and I notice quite a bit of blowing noise up towards the front window vent before the water temp warms up. After the water temp warms up, the hot air is blowing out of the front window vents. Is there any rhyme or reason as to which vents the Auto climate selects? Another weird thing I noticed is that when I hit the button to activate the dash vents, both the front and rear window defrosts came on.
