Not yet, I should go pick up the shut off valve. If I have it in hand maybe I'll get it done soon. I know the hot weather will come.Mid 40s in KC today,Hi! Any updates on this?

there's nothing else it could be ,ive been doing hvac for 23 years , a not cold enough air issue is low freon ,to much freon ,or incondesables in the system taking up space that the freon is suppose to occupie , making it read like there is enough psi in the system
true as I do residential / comm ac ,no blend doors lol, but if u r getting 50 degree air out of the vents or even 44 ,ac air will never be cooler than that , unless the evap coil in the dash is undersized and can't keep upYou need to also consider blend door actuators in Auto mode playing a role AND bad design when folks have 10 degree vent temp differences

Auto ac is different, you have that heater core that always has hot water running to it. Then the blend doors letting in heat to adjust your ac temperature. There's a design flaw or a malfunction that's letting in hot water to blend with our cold air. I'm going to install a hot water shut-off valve inline in my heater hoses to confirm my theorythere's nothing else it could be ,ive been doing hvac for 23 years , a not cold enough air issue is low freon ,to much freon ,or incondesables in the system taking up space that the freon is suppose to occupie , making it read like there is enough psi in the system
I have a rebel crew cab with pano roof it cools greatbig truck big cab ,not enough capacity

Well, my Mustang would blow 42 degrees out the vent on a 100 degree day.the air temp coming out of the vents should have a 20 degree delta , ie 80 degrees out 60 degree air
This is incorrect. Those are only 3 possible reasons for air that is not cold enough, and only apply to the mechanical side of the system, There are other mechanical issues that can cause issues outside of contamination or charge. r1234yf requires an inline hx between the low side and high side, which makes trouble shooting them difficult because you can't get an accurate measurement on the sub cool or super heat for the system to try an get an indicator of other issues like a plugged condenser or plugged expansion valve. Pressure on the high and low side only tell part of the tale sub cool and super heat fill in the blanks at to what is really going on with the system as a whole and because of the heat exchanger on this system you can't a total super heat let alone the super heat coming out of the evap coil.there's nothing else it could be ,ive been doing hvac for 23 years , a not cold enough air issue is low freon ,to much freon ,or incondesables in the system taking up space that the freon is suppose to occupie , making it read like there is enough psi in the system
but all u guys r not gonna have plugged condenser ,and its rare to have a bad expansion valve ,let alone all of u guys have a bad expansion valve ,also a bad expansion valve will make the head pressure shoot thru the roofThis is incorrect.

and make the vapor line freezebut all u guys r not gonna have plugged condenser ,and its rare to have a bad expansion valve ,let alone all of u guys have a bad expansion valve ,also a bad expansion valve will make the head pressure shoot thru the roof
my point is if the air is 50 coming out of the vent its doing all it can ,it could be undersizedand make the vapor line freeze
My AC sucks. I just got a new Infinity QX for my wife and it is a freezer. I have to turn the air down after a few minutes or get too cold. The RAM never cools down.
Hi Lydia,Hi Cygnus A,
We understand why this may be disappointing. Have you tried addressing this with your dealer yet? We would like to have this documented and looked into further if you would please send us a private message at your earliest convenience.

Me too. Noticed it this week, the first real warm one since I got the truck. Worse AC of any car I have had.My Rebel AC takes forever to cool, And it’s not cold enough.
I hope that you are wrong! We have 100+ degree weather most of the summerIt is pretty bad... even if you had the HVAC flash.
I am beggining to think that FCA cant fix this...
