Electric Window Guide Issue

[B737NGWS]

Noticed recently that wind noise seemed greater than normal from drivers window area. On closer inspection noted that the window was not seating correctly in the black rubber/plastic guide which it had managed to crush rather than slide correctly in the centre channel on forward edge of window near Mirror. A few up/downs and some coaxing seemed to have sorted it but can definitely hear some crushing in the door as the window is raised-something is not running as it should.
Anyone else experienced similar??

Not experienced that myself, but once the window rubber has been creased it is likely to carry on following that crease. The glass may also now be slightly misaligned in the regulator and need tweaking. I would expect the dealership to sort and replace the seal under warranty........

Pleased to report that some WD40 Silicone Lubricant (specially designed for window seals) seems to have cured it. A combination of seeds from trees,dust and unusually hot temps would appear to have prevented clean running in the guides but much smoother now.
