Hi Folks,
Both (driver and passenger) electric windows in my 997.1 suffer from streaks.
Even right after they've been cleaned, I just have to put them down and up once and the streaks return.

Does anyone else experience this?
Is there a way to remedy (ideally without having to remove the door card)?

Many thanks!

 

Very common problem."

Here's one discussion about it. There are many more. Try searching "Window Streaks".
It affects many Porsche models.

I have a towel in the car and wipe them away when they appear (usually after a wash or when the car has been wet).

I know it’s not a “solution” but it’s a simple fix that works for me.
