My 02 Z is doing the same thing, except that it is on the drivers side. These are scratches! It is getting worse every time I drive. And have the windows down. Took it too one dealership and they said that they thought that they could fix it by sanding it out. I said yea Right? You won't sand anything on my car. When I took it in they completely ignored the fact that the scratches were there and said I needed a new window motor. I said the damn window motor works fine what about the scratches. The mechanic said that the window motor would stop it from scratching. I said bull theirs nothing wrong with the window motor something is scratching the window every time I lower it. So what about my window? You need to replace it. He said the service manager is out of town we'll ask him what to do when he gets back. I said why don't you go ahead and order the window now so it can be installed when I come back. He said, I have to wait and ask the service Manager. I left. Also, has anyone had any problems with their clutch???? My whole car shakes when I try to take off when letting the clutch out. The car doesn't even have 900 miles and has been doing this since the day I brought it home. I took it back and told the dealership and they let this same dumbass mechanic drive it and he says it normal. So I take him for a ride and he tells me that I don't know how to drive a stick shift properly. I laugh at him and ask him what is properly? He couldn't tell me. So I left and found another dealership to try. I am suppose to take it next tuesday we'll see what happens. BTW the other dealership call me now a week later and said that the window motor was still not in?????????? Mine isn't broke!
