AC Blowing Hot Air: Codes B1476, B14AA, B14B8

I have a 2017 Prius Prime that is blowing hot air when the AC is activated. I do have access to a Snap On Diagnostic tool that showed the codes below:

B1476: A/C inverter load system malfunction
B14AA: Glass Humidity Sensor Circuit
B14B8: Refrigerant shortage

I have done a fair amount of research in this site as well as others, and it sounds like there is a common problem with the Servo motor. However, in another thread "Servo motor from hell" the codes in that thread were not the same as mind. I have also found some other cited issues related to the AC blowing Hot air when the temperature is above 85* and I believe that this applies in my situation as well. The other day the external temperature was in the high 70's/low 80s and the AC was blowing cool air. I'm not ready to say it was cold but it certainly wasn't hot. When driving home from work when the external temperature exceeded 85* it was blowing hot air.

Another code that was thrown for anti-lock breaks that I found to be interesting was:
C1241: Too Low or Too high battery volts.


I'm new to this forum but any help would be greatly appreciated!

Thanks in advance.
