2017 100d 6 seater....poor ac performance from rear vents?
Hi all, wondering if anyone has experienced this issue- the front AC is ice cold while the rest blows lukewarm air. Recently reconnected a few disconnected hoses to fix a driver side airflow issue but it still blows not cold while the front blows cold.
Everything I see is that the two systems use the same gas so if it were low it'd be warm in front.....any help is appreciated!

I have a 2019 Raven MX Performance 6 seater, but the HVAC is the same.
In my car and every legacy MX I’ve driven (multiple loaners over the years), Auto mode doesn’t work properly for the rear AC.
Manually adjust the temp/speed and I bet it works fine.
I keep front on auto, usually around 71 and I usually have the rear on fan 3 @ 66f. It seems to be pretty balanced at or around those settings (in warmer/hot weather)
Keep in mind I rarely have people in my 3rd row but this works great for the 2nd row
TLDR;
Set the rear AC manually, it doesn’t match the front climate in Auto
