Driver side power window friction

Hello,
Has anyone experienced friction with the exterior rubber seal grabbing / squealing on the glass when lowering, or raising the glass?
At first I thot it was sap, and cleaned it, but it happens quite often, and even this morning in the rain. Quite odd . . .

 

Don't know if it is what you are experiencing, but my driver's window was making a screetching sound when lowered. I had them look at it when the truck was in for it's first service. They said it was dirt and they cleaned out the tracks. The problem is 98% gone. I will get a slight noise of much lower volume every once in a great while now, but when it does happen it's usually gone by the time the window makes it all the way down. Some of that sap/dirt you mentioned may have gotten down into the tracks.

 

Got it, quite possible.
I’ll ask them, its got an open recall.
