2009 9900i A/C

Hello everyone. I'm having AC problems on my 07 9900i. I bought it used AC Was decent. After 6 months or so it got warm and I haven't had any luck with getting the system to operate correctly. The rundown is I have changed every component of the sytem Apads module, freeze thermostat, evaporater expansion valve even relays and fuses. I still can't get the sytem to blow cold. It get cool but not cold. As long as I am moving 40mph or better It blows cooler around 65 degrees or so, as soon as I stop goes up to about 85 degrees depending on outside temperature also. I am at a total loss. I have had professionals tear it apart put it back still same problem. I have torn it apart put back same thing. Does anyone have any idea of what might be the problem, and how can I fix this issue.

 

Yes air seems to be flowing through fine. I blow out the radiator regularly.

 

Front actuator door works the rear isn't moving but it's open to cold air flow. Heater core is isolated and not producing any heat at all.

 

My fan operates as it should even when fan override is on I still don't have cold air at idle.

 

Mechanic did it last but when I did It i want to say about 45 low 275 high it was around 90+ outside when I did it.
