If none of the power windows work, trying checking The engine fuse panel, Fuse # 110 and Passenger compartment fuse panel, Fuse # 14.
If both of these have power on both sides with the key in the run / accessory positions, next swap the Accessory Delay relay in the cab fuse panel ( relay #5 ) . You can use the trailer tow battery charge relay from the engine compartment as a test relay ( same size, full size Ford ISO relay ).
The radio could be a separate problem at the same time ( unless this was changed by the PO to run on the accy delay circuit ).
The fuses for the radio are in the cab fuse panel, fuses 1, 8 and 20. Test with the key in the run position.
Check fuses first to see that you have noon of them blown.
