Ok confused
Ok I just got off of Just Answers app and the person told me the reason my rear windows don’t operate is do to a bad BCM in my trunk.. Can that be right ??? I mean I have power at the plugs but he said it sends the single to operate, I thought that was the RVC job trough the CAN-B …

you need to open the front first and then start to open again and the back go down. or, just hold the buttons down...the front go down and after a slight delay the back one go down. If you tried that and they didn't go down, I have no other suggestions.

You're welcome...I've seen other posts on this site asking how to get the rear windows down, and other replies similar to mine to answer them. probably one of many reasons the rear windows don't operate

What do the rear windows do? Do they operate when opening/closing the roof?
Do they move when opening a door?
do they operate when you use the window switch on the door? (open side window, then operate switch again to operate rear window.
The rear windows are controlled by the VariRoof module.

Nothing to do with the BCM!

My issue has had me stumped for almost a year summer is coming and I want to get my top fix but my issue starts with my rear windows they will not respond to the door switches, center console switch. RVC module ( they won't normalize ) I'm using a autel 808 scanner and can see I think most of the functions the windows have power a both ends ( motor and RVC ) but there is no signal from the RVC ( I have replaced the RVC & Reaf SAM ) I have checked several grouning points . I can operate the windows with the plug from RVC unplugged
