Check for 12 volts at he following fuses for the BCM:
Minifuse(s) #25, 23 both hot at all times
Minfuse #13 - hot with key to on.
Minifuse #14 - hot with key to start (must be in park for an auto, or clutch depressed for manual.
If those check good, I would make sure you did not damage the wiring to the star connectors.

The BCM fuse #9, and Accessory fuse #11, receive 12 volts directly from the ignition switch. I was concerned the ignition switch contact was short/burned. Doesn't seem to be the case.

Wiring to these 2 connectors looks good. is there a test for it?

Not really, except for isolating the different systems on the class 2 serial buss. Typically when class 2 has a fault(short) it will take down all communication. In this cases, if the only codes you have are for the BCM and HVAC, then it suggests the problem is isolated to those systems, which is why I had you do the voltage checks. There are a few things to check. Since the console wiring was disturbed, you can try unplugging the HVAC control head. Then check codes, and see if communication is restored to the BCM. Not trying a wild goose chase here, just trying to eliminate common denominators, based on what was touched.

I get the same codes with or without HVAC plugged in.
