I have a '04 996 Coupe. When the window starts to go down using the window switch there is a squeak as the window moves away from the weatherstripping. The squeak on the drivers window seems to come mostly from the corner above and to the rear at the window corner.

Is there some maintenance lubrication that is needed? I have tried silicone and it seems to work for a while, but then back to the squeak before long.

The weatherstripping isn't brittle or cracked.

Try using rejex on the glass

 

Would RainX work the same? I have some of that.

 

Thanks Buzzm for the suggestion. RainX solved it.

 

Based on another user's recommendation, I tried Aerospace 303 on the window seals for the same problem on my '04 996 TTx50 Cab. It worked.

 

Mine happens only when the weather is warm..I guess I will give rain x a try also..
