The windows are working fine, but have been streaking/rubbing on both drivers and passenger same place. Otherwise the windows operate perfectly normal. See a couple other threads mention this but no conclusion on cause. Could it be a simply clean fix or is this an indication the regulator is going bad?
My C6 does that occasionally. I think it is grease that comes from somewhere inside the window motor/assembly. But seems to do this intermittantly.
I very carefully use a microfiber cloth with a very small amount of acetone (removes the grease easily) and then clean the glass with a regular glass cleaner.
I've replaced regulators in a different model car and I just don't think they'd fail in a way to cause that. Especially not on each side. I could be mistaken though. On my C6, the tint had vertical scratches when I bought it. No grease spots though. I thought it might be internal but had the tint redone anyway. And I wiped down and cleaned the felt. No scratches on the new tint.
I’d try soaping up that area or generous amount of window cleaner and before wiping it away roll the window down/up a few times and maybe it will clean whatever is making those marks
There are two felt pads near the top of the door that guide the window. They have a sticky back like the soft part of Velcro. They tend to move and the glue will leave a smudge on the glass. With the window down you can see them one toward the back and one toward the front. They need to be fixed or may lead to a permanent scratch. Have seen and done this before, the door panel needs to come off to fix it. They are very thin and kinda cheap, I replaced them and used the soft side of 1" wide black Velcro and cut a bigger piece for more glueing area.

Good to know. My driver window has been streaking a little and this is probably why. I better get to it before it causes damage. Thanks.

Finally got the doors open to check and you were correct -- the felt pad are missing entirely at the scratch areas. Is the soft side of black velcro the best solve? Do you recommend covering the entire metal disk that the window guides against?

Weird, when I bought my car I had thought it had a small scratch in the glass. Then I found out it came off with some thinner, so Hmmmm. I was able to peek down from the top and saw the pad. Being a self adhesive pad it had slid off and the adhesive was leaving a streak. Took the door panel off to access and simply replaced both front and back with the "soft" side of 3M Velcro, worked perfect.
