After posting to the group and trying to research Body Control Module or Control Module, I went back out and all the lights were back on, everything was working as it should. I pulled it into the garage and turned it off... but...

This morning I went out, started it up and everything was fine. The A/C unit was set to HEAT and FLOOR and the fan was off. As soon as I turned the fan from OFF to MAX, instantly all of the lights went off and the shifter says 2nd gear but I'm still in park. I tried to turn off the truck and it still runs (as before).. while the key is in the OFF position, this time I turned OFF the fan on the A/C unit and as soon as I did the truck TURNED OFF!!

WTF????????????

I can't drive it until I know what's going on. I don't want to get stuck somewhere or all of a sudden the truck's lights go out or I'm somewhere and I can't get the truck to turn off...

Please, someone brainstorm with me!!!

This is my daily driver

Reminds me of the old joke...
Patient: "Doctor, it hurts when I do this"
Doctor: "Well, don't do that!"

Seriously though, at least you have narrowed the search to the climate control system. Good luck.
