Hello, when changing air to roof vent, all air blows out driver side roof, passenger side makes a little noise but no air. Not sure where the blend doors are for rear AC. Thanks

 

Hello! I am having the same issue with my 2019 Sport. There is no air blowing out passenger rear roof vent.
I hope you were able to resolve the issue. If so, would you mind sharing the fix? Thank you

 

I pulled out the rear passenger ceiling vent by pressing the the small tab inside the vent. Pull down and towards the front of car to pull out. Once out, I noticed the door that swings open and close in there was stuck closed. This is why no air would come our. There is a little swing arm connected to the door that popped out and needed to be reseated. Fairly simple fix. I put a little grease in there so the door would swing open and closed easier. Vent snaps back in pretty easily and all working well now. That little swing arm can pop out again if you spin the wheel all the way until it locks in both directions. I found if I spin the wheel just until before it gets to the end/lock positions, there was no issue. If I fully spin the wheel either open or closed to the lock positions it would occasionally pop out again. See pics for little tab to pry open with small screwdriver and then pull out with needle nose pliers.

 

Thank you! I will try it soon and report back. Dealer wanted $2k just to diagnose it!

 

Thank you, thank you thank you! One caveat is that I needed to remove the vent cover using standard interior component wedges. Once I got the vent cover off, I was able to remove the interior compartment that you showed in the photos. The articulating arm seems rather complex and it disengaged from the small baffle/vent control, just like you said. Unreal that the dealer want to charge me two grand just to diagnosis! Thank you so much for your assistance.

 

Glad you got it resolved.

 

Worked great, thx
