Anyone else here know what causes this? I have seen it on many 3G Eclipses, Spyder or Hatchback. It looks like two big scrapes on either window, like it's rubbing up against something in the door. Took the door apart, and can't see what could be causing it. Maybe someone here has better eyes than I do.

 

I have it on both doors too. I just figured it was caused from window rubbing against the rubber and it must have had some sort of debris it at some point.

 

i hope that doesnt happen to my 3G eclipse
