993 with wind

[johnedwards]

My 1997 Carrera S is, according to my missus, suffering from excessive wind noise on motorway cruising. It is really only then it's a problem, as on secondary roads I like them open when alone! One of the door rubbers looks a little perished where feet have rubbed against it when getting in or out and unless the windows are shut tight they are floppy in their slides. I would appreciate any advice from other posters with experience of this who have replaced seals etc. Is it likely that it is the doors, or would the windows still admit air when tightly closed in their frames or could it possibly be the sunshine roof seals. Or perhaps there are other points of entry for the wind noise. Any advice much appreciated, so thanks in advance.
John.

I don't have a solution but just to say that mine seems to be impacted by wind noise on some journeys - even at slow speed.

It's so obvious when I set out from home at 30mph that I immediately think the passenger window is slightly open. I open/close the window but it makes no difference. Annoys me all the way to work. Then next journey it's gone.

So I guess it could be a rubber that is getting in different places when the passenger door is open/closed - which happens because GF gets a lift to work.

This is probably something else I shall be suffering from in the near future. I seem to be forever reading of issues on the 993 forum that I have no experience of until a few weeks after reading about them. It must be an automotive form of hypochondria []

Interesting thread. My car started exhibiting wind noise from the passenger door a while back. The local indy checked it over, confirmed the seals were old but intact and adjusted the door striker plate. This has resulted in the wind noise changing pitch. It is definitely still there.

I may go ahead and change the door seal. Does anybody know what is required and how to go about it.

Cheers.

Straight from Adrian Streather Book

1. Pull off old seal
2. Clean off old glue. (Use modified scraper etc)
3. Dry fit new seal and mark correct position of seal using tape (witness marks)
4. Once happy with positioning and witness marks apply adhesive to door seal first.
5. Apply adhesive to door chanel and install.
6. Do not close door until adhesive has cured.

Hope this helps

Thankyou all for your posts.
What I was hoping for was that perhaps somebody would have been through this syndrome and replaced various seals until they had found the one's which were causing the problem. Perhaps this is what I will finally finish up doing. I was just hoping to make it less expensive by finding, from somebody elses experience the correct seals to replace from the start. Of course I realise that my wind may not be the same as somebody elses!
I do have Adrians book but he doesn't say why he is telling people how to replace door seals. One just has to assume that they were causing a problem.
If any other posters do change their door seals, or window, or roof for that matter I look forward to hearing the results.
I think I will start with the doors and see what improvements I have-or not as the case may be.
I will post the results.
Thanks again to all who posted.
John.

There is a known problem with air entering the cabin around the internal door handles when the sunroof is open. There is a TSB with a resolution which was published on here a while back.

One of the 'tricks' used in the motor trade for this type of problem, is to place your knee in the middle of the door and with both hands bend the top of the door frame inwards.
