It only streaks at the very top of the window and at the corners about an inch or so on both windows. I constantly clean the windows and they magically come back. It seems they get dirty/grease whatever you call it at the window sealer. hmmm?

I'll try and take some pics tomorrow whens its light out.

I have an 05 Roadster btw.

 

Happens to me too. It's pretty common since it's the part that touches the rubber seal area. I just learn to deal with it...

 

there is TBS # for it now. Bring to your dealer to fix.

 

Just got back from the dealer and its not window grease. He says its where the window connects to the top.

 

will the dealer fix it since there's a TBS# bulletin?

how will they fix it?
