Inside, both windows, vertical, about 3/4-1" wide, closer to the rear.

Pisses me off, cause I just cleaned them....

Have lived with this on both D and P side windows on both my 997.1 2008 C2S and my 997.2 2012 C2GTS. My service guy says it is a lubricant for the window mechanism. Seems sloppy engineering in an otherwise supremely well engineered car but as others have said what the heck, clean the windows more often. I keep a small spray bottle of eyeglass cleaner and a microfiber cloth in my door storage box, which also works great for removing dried doggie nose prints (we have a pair of Toy Manchesters who love to ride in my 911!).

This seems to be a constant issue with the 997 models--coupes as well as cabriolets. And age is not a factor. When I first took delivery of the car it was a PITA but I adapted, yet now many years later it happens again periodically. Because of the cabriolet top I keep paint cleaner and windex along with two rags in the car at all times. (The canvas top should be tackled immediately if a bird targets your top or paint).

Yup, seems common. I think it's moisture or some type of oil on the felt.

This has happened to me. When I was working up in the Mojave desert with the high winds and blowing sands I must have collected a bit of sand in the inner window trim which acted like a mini-diamond cutter every time my window went up and down and has left a couple of vertical lines on the inner glass which can be felt with a fingernail. I don't think there is any fix for it other than replace the tint. I'll live with it for now.

It happens on my '09 cab. It's residue from some lube inside the door--probably off of the window regulator. My streak is fairly wide and happens to both doors.

If it's gotten into the window felt, it'll be a problem forever. I had chalked this up to a unique problem that only I had. Now that I know it's a common thing, I find it unacceptable for a car at this price point.

It is a common problem with our cars. I always keep a micro fiber towel in the glove compartment and just wipe it down when needed.

I have the same problem as well. Mainly on the passenger side. It forces me to roll the windows down while driving, but that is fine because of where I live. It's always nice.

I agree. Mine does it bad enough where it affects visibility through the driver's side window. Maybe this is a warranty item. If it's not then I guess it's considered normal having to carry a rag to wipe down the inside of the windows every time they're rolled down.

Old thread. But wondering if anyone else that had this issue found a fix for it. I am seeing this a lot on my GTS. I am not worried much about the streak as much as I am worried about getting tints and if this might scratch the tints.

Wow - Same here on my 06. Never said anything because I just thought it was the tint and not worth mentioning. Misery loves company lol!

I don't get the streaks on my GTS cab but I get a couple small round impression marks on both driver and passenger windows.
