GT3 greasy side windows

[G T 3]

My mk2 has a greasy streak on both side door windows inside where a quarter light window frame would be if it had one.Clean it off and then it comes back when you open it..Any ideas?

I have the same on my C4S

I assume it needs to go back to the dealer to let them take the door apart and clear the inside?

I had the same thing on my MK1 GT3, I put the window down and cleaned the rubber both sides.(on the door)
It may take two or three goes, but worth a try !

IIRC there's a felt pad in the door that acts as a guide and this gets contaminated and leaves the streak. Shouldn't imagine it's too much of a job to change them.

Same problem here, I have two 10pence sized marks on the front and rear of the door windows which streak when the windows are operated...

Learnt to just live with it and clean off when the car goes back into the garage.

This smeary mark on the insides of 996/997 windows is a common problem. Your OPC will have the door apart and give it a clean if you really want them to - but I just live with it, 'cos even after they give it a clean it will go back to smearing quite quickly.

Think I will live with it, if it is common.Ta

Same problem here on a Cayman.

Took it back to the dealer and service manager said it happens across the range with no solution.

hahaha you evil git!

Get some of that spray cleaner that has citrous stuff in it, spray on window on streak... raise lower raise lower

clean window then repeat with fresh water

it'll get the cleaning agent down into the greasy spot inside ya window, but will seem like youve made things worse to begin with.

Or take them apart and clean inside the rubber strip (it'll never go back on tightly again!)

Or replace rubber strip.. be ready for leaks until it settles itself into place, easy to fit... rubber mallet usually.

Tried to get my finger in "the greasy spot"....got a slap!

Also; GT3 + MALLET = SCARED

Windscreen guy told me how to fit them.. worked on my 944
but then it's a lot easier to whack a 3k car than it is a 90k one

Hi Guys, i have come across this on all 996 onwards cars and after doing some digging i am told that Porsche put some rain repellent on bothe front side windows, why it is these 2 only i am unsure.
I have found either add rainex or use a degreaser to remove it and then clean as normal.
