Relay fuses or electrical diagram for interior

Trying to find out what the "relay control center" controls on the vehicle listed above Ram Van 2500. I'm having issues suddenly with no turn signals (but hazards work), the radio won't turn on, and the windows won't move all at once. I'm thinking it's a relay as those are mostly different fuses. (Other thoughts are appreciated).

An interior electrical schematic of the radio and windows would help to see where there are cross overs between the elements.

I found the exterior electrical diagram someone kindly posted dealing with turn signals.
