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.

Thanks everyone. I'll start with the master switch. I double checked the connections on the rear door (regulator and body control module). All were ok. It's possible the brand new regulator/motor is defective but not probable. I'll check the other options first. I usually buy online from Rock Auto and Auto Parts Warehouse. Is there a better recommendation? Thanks again!!
Do I have to remove the whole door panel in order to remove/replace the master window switch? I'd rather not have to remove the whole panel if I don't have to.
to test the regulator just get 2 sets of wires about 4 feet long each and run it from the positive and negative off the battery to your new motor and if it runs it works that way you will know it is good! don't mix up the posititive and negative wires ! if u can pull the window switch away from the door enough to get the voltemeter probes to touch the connections and you will know whethr there is power going to the motor!
