I hate being that jackwad but here's the fix. Is the same fix to make sure the back isn't 10000F in cruise. Open your vents. I know the air blowing out is cold. Let it blow cold, in 30 seconds or less it'll burn like a hair dryer. Every problem with the 900 ecs is tied to the captain and FO not opening those giant air vents because the lines are cold soaked for the first 10-30 seconds of blowing. If captains can additionally point their air vent down (chest level, not to the floor) and to the left so the air wraps around you and blows around to the temp sensor behind you on the floor you're gonna be shocked how quickly the temp regulates in back. Leave the ecs screen up, do what I said, wait 120 seconds, the temp in the cockpit will raise or lower (whichever you were trying to do) in earnest. The sensor will essentially come up to a normal temperature and then the ecs will start blowing colder or warmer air depending what you were trying to do beforehand.
Left pack off for all door open ops (boarding). If it's 15f or less outside keep the cockpit door closed as much as possible during boarding with the left pack off. Additionally, it's not approved anymore (when I was there) , but run in manual mode at about 30c on left pack on if it starts getting Montana or Canada cold. It keep you from death.
Keep the left pack off with your air vents open in cockpit until after engine start during pushback and you won't get dragons breath in the back of airplane.
Alternatively keep making it awful for passengers and flight attendants in the back.
