996 window weather stripping

[zjones]

I am having issues lowering both front windows on my cabrio. The weather stripping is catching on the windows and curling under as the windows are lowering. It is happening on both the driver and the passenger side windows and seems to have started abruptly. Check out the pictures for a better explanation. Is this the first sign of the weather stripping going bad? The seal it self appears to be fine. This is causing so much extra friction on the window that I am afraid I will burn out the regulators with continued use.

The pictures show the problem within the first inch or two of the window coming down. By the time the window gets half way down the whole piece of rubber has curled under and causes the window to move at a snails pace (cant be good for the motor either)

All I can think is they need to be cleaned or lubed in some way or that they are in need or replacement. Any ideas?

Have the window treated with a silicone containing detailing product to start with, if the result is not satisfactory, replace the seals.

I ended up treating the seals with tire shiner (recommended by a detailer) and the window with Rain-x. The windows function like new.

My solution is to use concentrated washing up liquid

(the stuff you use to do the household dishes, maybe another name in US)

I apply it all over the windows inside and out, and just run it along

the rubbers. I usually leave it on for an hour, maybe better leaving overnight

in the garage. Always worked for me 100%. I'm told it returns moisture

to the rubbers, and revitalises.

Your rubbers look perfect.

With all due respect to previous post regards silicone products.

I'd recommend never to use the stuff near a modern car, especially

aerosol products, it plays absolute havoc with electrics - like radio

switches, alarm micro-switches, central locking switches etc...

It also produces a thin layer over paint work, making it a nightmare

for any body work repairs.. any body shop repairer will testify to this.

The window glasses have a small screw to regulate the vertical tilt, all the way in the bottom of door. Don't remember if outside (need to remove door panel see DIY here) or outside. This could help to make sure the window is not too tight.
