993 Windscreen 'Watery' Noise
Discussion
Hi All.
A quick query. I have a 993 (C2S, ’97), with an irritating issue.
There is a watery sound (I can best describe as a type of trickling or maybe a tiny pot of water boiling!) which seems to be coming from the base of the windscreen. This noise starts at c.40mph and gets worse as speed increases, meaning by 70mph is feels as though I’m sat in a water garden.
It is only bad after the car has been left out in the rain.
The obvious answer I would have thought is that this is either a windscreen seal issue or a drainage pipe, with the airflow creating negative pressure and moving any residual water around. However, I’ve taken the car to my local specialist and they thought it was something to do with the air con (I wasn’t convinced and what they did hasn’t worked).
What do people suggest? My own view is to get the windscreen taken out, get any tiny rust bubbles done in the usual spots, and get a specialist to refit.
Thoughts?

You should be able to remove the outer trim on the front screen quite easily. Do so - it has no function other than cosmetic.
You will then be able to inspect what is going on and make a more informed decision. Did your 'specialist' not do this?
Also, if your 'specialist' thinks that the aircon makes more noise over 40mph, it's time to change your 'specialist'.

Any history on the installation? Who did it? There are some simple tests to identify the problem; IME the most likeliest cause is non-contact, IOW, the windscreen isn't stuck to the car very well.
Both, thanks.
I'm going to go through the folder for who installed. I guess the answer is to get someone good to take it out and re-fit it then if this is the case? If so, does anyone know who in the Saffron Walden / Cambs area could do this (properly, as it seems to be an acquired skill!)?

Have you taken the trim off yet?
NB the trim came in two versions - the difference being the section of the trim that 'keys' into the channel around the windscreen. One type is easier to remove than the other, but if you stretch the trim lengthways, the profile usually pops-out. Use a wooden or plastic ruler to help you get under and hold-of the trim, then there's no chance of scratching the aperture.
If you rip the trim, you can just buy a new one, which you'll probably need to do anyway when the screen comes out.
Skim-read down to the bottom of page four to see what I mean.....

ETA I think the front trim profiles are different, not just the rear one.
