Recently, I have a couple of thin vertical scratches on the power windows. Started on driver's side and now the passenger side has it.
The windows must be rubbing on something as they go up/down.

Has anyone else experienced this and knows if there is a dealer fix?

Also, if anyone knows if there is a product to remove window scratches that I could try........

 

are they scratches or grease streaks? cuz the Z has had problems with grease getting on the windows

 

I've heard people talk about grease streaks problems with the '03. My Z is '04 so I assumed I was safe.
But, if it was grease streaks, these should have come off when I washed the car - yes? These marks are still there no matter how many times I wash/polish.
It's bugging the c**p out of me.

 

try cleaning the inside. the grease streaks get on the inside of the window not the outside.

 

Already tried it dude, didn't make any difference
