Weak airflow from rear passenger vents

My 2023 1794 has the rear a/c vents for the rear passengers in the back of the center console but no matter what HVAC mode is selected or fan speed, the airflow from these vents is very low. Does anyone else have this problem or am I not setting something correctly?

 

Make sure you haven’t turn back air off with switch above center console

 

Which switch is that? I can’t find a switch specifically for the rear vents nor is there any mention of such a switch for the rear in the owners manual. The modes switch only affects the front passenger vents from what I read.

 

Bottom row of buttons right side if it lite up vents are off

Littleschipper -- Yes! I agree and noticed same, the air flow IS a problem and the fan control button for the front also controls back but it is NOT enough flow and .... my 2023 1794 has the "Outside air mode switch" in this location not the one here posted by TB2 which I assume is a different trim.
Hmmm....

 

I have 22 1794 hybrid

 

Okay, I figured out why the air is so weak. When I first thought there was a problem my daughter was in the back seat and I asked her how the airflow was (her first time in the truck.) She said she could barely feel it. So, from the drivers seat I reached behind me to the passenger side rear vent and confirmed low flow. That’s when I tried manual fan speeds, mode switch positions, etc. nothing seemed to change it. Then today I turned on the a/c and jumped in the back seat to get a different perspective. The problem was the vent blades to direct the airflow were almost vertical, practically closing the vent! I pushed the vent direction tab all the way down and voila! Air was flowing profoundly better. From the drivers seat I couldn’t see the position of the vent control and only feel the air blowing. There isn’t much leeway with how much the vent control is pushed up before airflow is restricted. So when it’s a hot day and the a/c is on, pushing the flow direction tab up very much to send air up into the cabin rear diminished the flow. It appears the best flow is when it’s pointing to just above seat level. Thanks to everyone who looked at this and they were wondering why their vents were working fine, just figuring I’m the village idiot. Doh!

Correction:
The vent tab was moved sideways, not vertically, to control the flow. All the way to one side shut it off and it was almost completely closed before I got in the back to see for myself.

 

Thanks!! Solved my issue. Had passengers in my truck for the first time yesterday and had no airflow in the back. This post fixed my issue. appreciate your response to the OP
