Hot air blowing out Vent when stopping
I have had a problem in my Laredo with the air vent pushing out hot/warm air when making a sudden stop or just as I take off from a stop, or stop and go. Almost reminds me of the dreaded blend door issues from the WJ's. My Limited doesn't do it.
I'm guessing the vacuum must hold the door in place and when the vacuum gets too low it allows the door to move and allow the hot air to move into the vent. Just a theory.
I'm taking it into the dealer today and have them check to see if there are any codes from the HVAC. I know there used to be a way to check the codes by pushing the buttons but I have no clue with the 2011's.
