All my power windows, locks, mirrors, and key fobs do not work. All fuses are good. I checked all three boxes. Drivers door connections appear good. What controls all these functions and what is most commonly the cause of this please?

Closely inspect the wiring harness in driver door jam
check for power and ground at the driver door window switch
if have power and good ground have to suspect and scan BCM for codes and fault ,as it possible to be a BCM failure
