Controls? Modules? Why make it so complicated and mysterious???
Very simply, you have a bad switch. You can get one from a salvage yard or a new one from the dealer or parts store. Takes about a minute to replace. There are no exotic mysteries or black magic going on!
A power window switch is very simply a DPST (double pole, single throw) momentary contact switch that is hard wired to the battery and the window lift motor. There is also a power relay that provides power to the switch. Here is the diagnostic: If one or more windows operates, the master switch on the driver's door is receiving power. If one or more of the remote windows does not operate from the master switch, but operates from the remote switch, the master switch is bad. If windows ONLY operate from the master switch, then the window lock on the master switch is activated, disabling the remote switches.
Over the years, safety features have been added to make the power windows safer for young people. A relay is used to cause the windows to be powered only when the ignition switch is in the ON or ACC positions. Another relay was also added to allow the windows to be operated after the key is turned off - untol a door is opened. This allows closing the windows without having to restart the car.
Also - and somewhat less common is the wiring at the driver door hinge area. There is a wiring harness that goes from the door to the body for operating electrical devices that have switches in the door. In older cars/trucks, it was common for high mileage vehicles to have broken wires in this harness from repeated opening and closing of the driver's door. This is less common in later model vehicles due to improved wire alloy, friction reduction, and strain relief.
I speak from over 45 years of fixing these things for a living.
