S4 b8 a/c issue

[Lighting]

Did a complete evacuation of the system, flushed, vacumm and reloaded the refrigerant. A/C doesn't blow cold, it's not a control issue because when I raised the temperature the heat blows hot but if lowered it doesn't blows cold. Double checked the pressure of the system, added the right amount of refrigerant gas and lube also there are no codes. I'm overlooking something or are there any adaptation that needs to be done. I purchased the car a few months ago and it's been great and very happy with the performance. Any and all help will be appreciated.

Are you on manual fan control and is the AC button illuminated?

Buttons iluminated and module control as it should. Raise the temp and heat come on, fan working good and all the vents control operating properly.

Well that pretty much exhausted my knowledge of A/C on these cars, hopefully someone else knows!

What are you using to scan for error codes? Standard scanner not specific for our cars don't always pick up climate control issues.

I had my A/C Pressure Switch Sensor go bad and it immediately fixed the problem. Per the suggestion of my OBDELEVEN scanner.
