Air Conditioning blowing warm air on 2009 A4 - anyone else had this happen yet?

It was about 70 degrees on Saturday so I turned on the AC, but it just blew warm air.

Wondering if anyone has had this happen or has had similar codes…hoping it’s just a replacement of the sensor. Havent seen a DIY on that anywhere, so if you’ve seen one, please link it up.
