I understand exactly what you are saying. I had previous vehicles that would wait for the air to be warm before blowing also but most of my vehicles would start blowing before the air actually felt warm. It may have been warmer but sure didn't feel like it. I also have current vehicles that start automatically with the defroster on and the heated seats on when the temp outside is cold enough to get ice on the windshield and the ac comes on with the cooling seats on when warmer outside. I wonder if the EX has different settings than the SX. I also have a sync setting on mine along with an auto. I am starting to think I am lucky that the AC/Heat stays synced and stays in the same state, on/off, it was left the previous time the Telluride was used. My owners manual reads like that also. The rear ac/heat will stay off at the next restart if it was turned off before stopping the car. It will come on and be synced at the same temp as the front at the next restart if it was set before turning the SUV off previously. If these posts are any indication of the way most acts I thinking I am very lucky.
