If compressor still won’t kick on, try to manually engage it by injecting a signal to the compressor directly. If that still doesn’t work, compressor is bad. If it does work, you have electrical issue which will require you to trace the wire.

I also don't believe the compressor just quit. It's an input somewhere that's telling it not to.

Update. The system did take Freon. So I now have new codes. Which to me are pointing to an issue with the IHKA itself. Obviously not 100% sure my research is finding that it seems to be a communication issue. I very much appreciate the responses. This is the first time I’ve ever had AC issues with any car I’ve owned, and it feels defeating not just being able to diagnose it.
