Best I can guess is you may have fried something reconnecting the batteries. Im guessing there is an expensive fuse that has popped. My other '08 had a bad wire and fuse that needed to be replaced.

Do u know what fuse and wire it was? I checked all the fuses, jcase fuse, and mega fuses and relays under the hood and inside truck. Also replaced all the important fuses with brand new ones just in case

It was the mega fuses. And the wire from the fuse box to wherever.... hope this might help somehow.

Gotcha. Thanks ya I changed one of them and the others were good. I’m almost positive it’s my BCM. I lost communications to almost all of my modules. I bought a $350 Innova 5160rs scan advisor professional code reader with RepaorSolutions2. It’s pretty badass for the price. Anyways for some reason I have a bunch of water under my drivers side carpet and the insulation is soaked and water puddled up all on the wires running along the floorboard. Not sure if that has anything to do with it and could’ve got my BCM wet. Is there a test I can do to see if the BCM is working properly and be able to find out if that’s it or not? I took a cpl short videos but won’t let me upload on here to show what my dash is doing when I turn the key to on and all the water on floor and wires. FML nothing can ever
be easy!

I'm at a guessing point same as you and I don't want to be misleading.

As far as the water it could be the hole(s) on the roof.

My '08 leaks from the satellite antenna and my yellow markers in the middle.
