The window fix is to replace a little plastic piece that snaps and lets the window completely drop into the door. I know that on 93's, you do not need to replace them because then have been corrected from the factory.
If you window is slow, like mine, you may need to greese your window tracks, or replace your window regulator.
Hope this makes sense....but if you install the window fit its on your 93, your window will still be slow.
