But is that a big deal?

The bigger issue I have is that my windshield washer fluid reservoir keeps freezing, and then if I am driving in bad conditions can bring me to the side of the road! I've had the dealer change-out the fluid twice, and I've even added my own fluid mixture to prevent freezing. But it keeps happening. I think the placement of the fluid reservoir up close to the hood and near the windshield causes this. Not sure how there would be any warmth to this area at all.

Anyone else experience this in winter conditions?

When you close the door, the window glass stayed at that up position and the door cannot be closed properly where the glass stayed outside of the trim at the roof line. Just wondering if that is a problem with 991.

Last year there were many days my window wouldn't go down when I opened the door (because of why you said) and wouldn't seal properly when I closed it. Each time I felt like I was damaging the seal around the door, but Porsche just shrugs their shoulders and says, yup that's unfortunately how it is.

You think they would have solved it with all the cold weather testing but nope.

People talk about sliding a credit card in to separate the glass from the trim, which I think could damage the seal. The ghetto way that can fix this problem is to apply painter's tape along the door to minimize the amount of water that gets in. Works well but looks terrible.

The other option is to wait for the car to warm up enough so it'll start to melt. Or keep pressing the window switch to hopefully unstuck it(risking ruining the motor).

I use this stuff on my wife's SUV all the time when she leaves it outside overnight. Clears the ice right off the windshield while waiting for the engine to warm-up. No scraping.

I've also ready you can just push down with both hands on the top of the glass (carefully) about 1/4'' to unstick it.
