cold air draft on pass side no matter what setting the cc is set at:(

[xspsi6]

I have never noticed this as I live in Florida where it never gets real cold however I am traveling to Chicago where it was below zero some nights and just really noticed this and it coming from the passenger vent closest to the window so I have googled the issue to no avl but maybe someone here can chime in on a possible cause so I can get it fixed before i leave Chicago.

I've got this problem too and I have no idea what causes it. When I close the vent the center-right vent goes cold.

ive got it as well.

cold air comes in when the fresh air is on but not with recirculating.

My thoughts are that there is a a leak in the HVAC unit and the cold air coming in from the outside is pressurizing the system before the blower fan and coming out by your feet.

Hmmm so this is a semi common problem with these 3rd gens so when I get back to Florida I will dig in to fixing it as I cant deal with little issues in my near flawless truck which I love and treat very well.

I have the same issue. Does anyone have access to an exploded diagram of this system?
