From what I can tell you can’t reasonably keep the ac working in these cars, the hybrid batteries are always failing and there are recalls for fire risk to contend with.
Even though the car runs fine without the hybrid battery once it fails the 12v stops charging.(sound familiar) and no one has come up with a way to bypass
I really would like to get it for an injured relative to use as a winter beater (body is rust free, just high miles) but it’s just too risky to try and keep one of these running and on the road

Late to reply, but a bypass to get the 12v charging again should be relatively easy. The altermotor will have 3 phase lines between it and the motor drive unit, which rectifies it to DC and connects to the battery, which then connects to a DC-DC converter.
I have verified all Honda DC-DCs just turn on and work once they start receiving power, whether it's a 2000 or a 2015. If 12v isn't charging, it's because a relay has disconnected HV from the DC-DC. You can either bypass/short the relay, or just connect the high voltage lines straight from the motor drive to the DC-DC.
If for whatever reason GM's DC-DC required an ECU to turn it on, and it's inactive until that happens, there are aftermarket units available in whatever voltage and current range you want, starting around $100, and you simply connect them to the output of the drive unit.
