your master control module is bad..we just did this with a close friends' jeep.. it went all funky and I couldnt figure it out at first..the dealer we took it to fixed it because it was and still is under warranty.. thats what was wrong with hers..
Window regulator most likely but before changing it out take the door panel off and apply current to the contacts of the actualy regulator. If the window goes up then switch the contacts and now it will go down. If nothing then regulator (window motor) is bad. If it works then your master control switch for all the windows is going bad.
Do you know anything about automotive electronic's , control module's , using a factory or professional scanner to communicate with said control modules ? Here is a list of componets involved in controlling the power windows ,lock's , driver an passenger door mirrors .
Power Window System Components
The power window system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Body control module (BCM)
• LR power window switch
• RR power window switch
• Window up and window down relays in each of the rear passenger window switches
• Window lockout switch
• Reversible power window motors in each of the doors (circuit breaker protected)
• LT DOOR CB 25A (System power for left rear window)
• RT DOOR CB 25A (System power for right rear window)
The power door lock system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Liftgate Module (LGM)
• Door lock relay
• Door unlock relay
• Body Control Module (BCM)
• Reversible door lock actuators in each of the doors
• LR/RR LOCKS 10A fuse (relay supply voltage)
• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)
I don't think the switch would be the problem , more then likely broken wire's inside the flex boot from the body to the driver's door . See this more often then the switch going bad . Just replacing parts could get expensive . I would think a power wire or a communicate network wire broke .
If you have a multimeter you can go to the underside of the master panel in the drivers door and independently check the switches for voltage or with no power to the switch assembly check for continuity. Good place to start. If you get continuity to through the switch then you need to check power to the window actuators in the doors.
This may be just a case of inadvertently hitting the window lock out n th driver door window switch by mistake. Check that first. Here's some background on window operation
Principles of Operation
The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.

I think on that year there is a safety switch on the inside of rear door jam so the children cannot roll windows down and fall out. It should be on the back door when you open the door look for a caution sticker that says child protection switch, I sure hope thats the problem And if so Great If not get back to me I can look up where the power relay is for rear windows. Ok Take care, Bear001
