For windows check items in pic then see if switch is getting power or not it may be a broken harness in door causing problem. Sunroof use the same relay but have it scanned to see if the body module or sunroof module is problem.

Check items in pic they are separate you may have a bad relay you'll have to find it as it's taped in harness. Could be a bad switch as well if yo have pwer to switch an dnothing coming out of it then the switch or module is bad an dit's all one piece.
