I always thought the plastic brackets holding the glass broke or the channel was too tight and that caused the binding problems, but I now believe the root cause is a slightly tilted factory install of the window regulators.
When I first got my VX my windows were broken and would not even roll up if you rolled them down.
After I got it home we took the door panels off to see how bad it was and it was bad, the previous owner had continued to use the windows and force them up tearing up the weather stripping and all 4 plastic window brackets were broken one so bad the glass could have fallen in to the door if the other one let go.
So I got the metal brackets and the windows were still binding and would not roll up straight even after replacing the plastic window holders with the metal brackets, it did make them better because the plastic brackets were badly broken. I also widened the front channel as people suggested but still they would tilt. I even replaced the window regulator and weather stripping and still the window was binding.
So I thought there has to be another reason this is happening and after taking off the door panels and looking closely examining how the window regulator was installed I could see that the mounting holes were slightly off so the window was just slightly tilted forward and it was a very slight tilt so it was not readily apparent it was skewed so no matter what I did the window would always roll up crooked and bind, then I could see this was the likely reason the plastic window holder brackets got broken in the first place and why the weather stripping got all torn up.
So to see if this theory was correct we unbolted the window regulator and made the mounting holes slightly slotted front to back so the regulator could be slightly moved to adjust the regulator at slightly different angles until the window rolled up without binding and low and behold it worked and all of the sudden the windows rolled up and down as normal windows should.
I used a drill bit the same size as the top holes and pushed it side to side (front to rear) to make the holes slightly slotted so the angle could be adjusted. On mine the top of the track needed to be pushed a tiny amount toward the back of the VX so the glass would follow the rear channel and not catch the front channel on its way up.
Remember all VXs are different so you will have to see what works for yours and some may have to do the bottom holes too. On my passenger side I just loosened the bolts and pushed the top of the track back and the bottom forward and re tightened the bolts and it was good to go, the driver’s side did need hole mods to fix it.
It only needs a LITTLE adjustment, if we pushed the top too far back it then would bind in the rear track so it took a few tries to get the angle right so it did not catch the front or rear channel.
They have been working great now for 6 months no binding at all both sides work great now.
