Hi Guys
It looks to me as if the window guide inside the bottom of the door is making the glass go up into the frame slightly too far out.
Ie when the door glass goes up it rubs the outer edge of the "u" channel causing it to catch more of the outside section
View attachment 206047of the rubber dragging it up into the "u" channel.
I hope the basic sketch makes sense, there must be some adjustment for this

ps, there used to be little hard rubber triangle thingys on the door rubbers as guides but they all seem to have disappeared probably and aid the aerodynamics
