fuses
My rear fuse box got flooded and Ive dried it out and all functions now except the infortainment panel. I don't know which fuse, switch or relay to check to see why I have a blank screen. The radio doesn't work, the other buttons or home button don't work either. Can turn it on or hear anything from the speakers. Any help on which fuses or relays or switches to check?

I see you have a 2019 Grand Sport from your profile. Note that fuse numbers have changed from year to year. You should download pdf versions of the owner's manual and infotainment manual if you haven't already.
Blank lighted screen or dark screen?
There are several fuses in the under hood fuse panel labelled HVAC, radio, center stack, and body control module.
In the rear I see amp and more body control module.
Since the center stack, AC controls, and radio are out I would start there. It should not be too hard to run down the fuses with a volt meter with ignition on (engine not running) or in service mode (hold the start button around 10 sec without your foot on the brake or clutch). Be sure to push the start button again to exit service mode. You can search the manual for more info on service mode.
I've attached the 2019 front and rear fuse box diagrams and schedules below.
