Default Please Help 2006 STUCK in accessory mode

Hi to everyone, I hope that one of you experts can help me with a very complex issue. I will spell out what happened.
I was detailing my Vette. It is a 2006 base model automatic with just over 22k miles. I have never had a problem with it except a random light for service traction system that has come up three different times and always goes off. The car does have the random stuck in park issue but always releases itself if I am patient and push on the shifter.
Here is what happened. I had the doors open, the hatch open, the hood open, the top off, and the windows down.
I Vacuumed the whole car, wiped the engine compartment, Wiped down the dash and controls including the switches, (using a barely damp with water cloth) cleaned the leather and the windows.
I removed the floor mats and reinstalled after vacuuming the whole car under and behind the seats.
When I was done I went to start the car. The starter engaged but did not spin or start. I pushed the button again and it clicked as if the battery was very low. I then tried three or four more times and only got a click. After the third or fourth time it stopped clicking and went into accessory mode.
The battery drained quickly and I ended up having to unlock the car manually and pop the door latch. At some point during this all the alarm went off and I silenced it with the FOB.
The car is still locked into accessory mode and wont time out, or stop draining the battery no matter what I do with disconnecting the battery or pushing the switch.
The Display says Accessory mode. I cannot access any other functions on the display. I tried to get the DTC's but none of the buttons ( reset, gas button work).
It's locked in accessory mode if the battery is connected.
The radio works, the windows work, the seats will move, the hatch pops, and doors lock and unlock with the FOB. The brake lights work, the horn, wipers, lights etc. all work. The panic button does not work nor does the HVAC system.
I have disconnected the battery and charged it over night. This had no effect when I hooked it back up still in accessory mode.
I had the battery tested it showed good at 12.6 volts.
I changed the batteries in both FOB's.
I went ahead and bought a new battery just in case there was a week cell in mine.
I have disconnected and reconnected the battery several times.
I checked every fuse in the car (both fuse boxes).
I unplugged both blue wire bundles under the passenger side kick panel and reinstalled.
I've put both FOBs in the glove box slot. I took out the console and checked both of the micro switches on the automatic shifter both make a connection and have continuity.
I've removed the ignition switch and reinstalled it.
I'm out of Ideas that iv'e gotten off of this forum and others.
Sorry to write such a book but I'm very frustrated and worried about getting this resolved. PLEASE HELP
