Yeah... well, dealers have tried to blame the Isuzu window binding problem on wind deflectors to a few here in the past as well. Understand this... I'm not sure if they've actually come up with a fix for this, or if they are still just "adjusting" the windows and leaving them at that, but it may happen again down the line. Mine were "adjusted", and started binding again within a few months. I've tried bending the track, and they go up a bit better now, but still bind.
