Admittedly, I have not read my owner's manual thoroughly as of yet...but when I have the A/C on, if the Manual Rear is not activated on the dash, hot air (I mean HOT) blows out of the second row air vents while cold air is blown out of the dash vents. When I activate the Manual Rear Control button (i.e. green light is "ON") the second row will blow cold air to temperature the second row dial is set. What's up here????
