Dont buy any new parts just yet. its likely a problem that can be solved easily.

as shown in the previous pics it could be in the harness where the ground is (in the DS kick panel)

mine was actually a broken wire in the door harness itself. I had to pull all the door harness plugs, take the coor panel off and pull the wiring cover back to expose a broken wire in the door hinge area.

in my case, the windows would work, then id open the door and it wouldnt (or vise versa.) then it just stopped working all together. neither window would go down. The DS switch would buzz when pressed, Pass side, nothing at all. sometimes the door locks would open and or close on their own after trying to open or close the window. Even the alarm went off once or twice. I pulled back the harnesses rubber cover and found a broken wire. Make sure you solder it properly and heat shrink it. Using butt splices and stuff is just asking for it to happen again.

Hi There , Yes I have same problem with the windows they failed at the same time , that's not normal to have both motors fail same moment . Any when I depress on window button to make go down the light
near the window button dims and that sounds like some kind of short or not a proper ground . So im believe your story very much . If possible can you tell me how you fixed this issue . Thank you

Pull the control unit up out of the door panel. Locate the ground wire from the switch unit. In the 92 model, this will be a white with black stripe wire. The 97 also it is white with black stripe, so I assume all models are this same color. Ground this wire temporarily either by stripping back some insulation and running a wire from there to ground or get into the wire in the plug and run the temporary ground. When you have it grounded and the control panel plugged in, see if the windows will operate. If so, you have a broken ground wire. I just spliced into the wire and ran a new wire directly to ground just to keep from having to try to locate the broken ground.
