Have you check the fuses? Almost sounds like a blown fuse because so many things are inop. In your owner's manual there is a list of them and where they are located. If you don't have an owners manual, I believe National Corvette Museum provides them free of charge in PDF format.

Replace the fuse and see if you can get it into diagnostics mode. push and hold the up/down arrow buttons at the same time for 5 seconds. The LCD will display 00 Push auto fan and it will display AC codes.

Does it only do this when you press Auto AC (not fan switch), what about defrost or vent?

Also which specific fuse is it blowing?
