I took my car out from the underground parking and went for dinner yesterday evening for about an hour and returned to find moisture all inside my windshield. The defrost cleaned it up within a minute.
I’m asking for assistance to find the cause.
Troubleshooting facts;
- car was parked underground all day and weather was sunny around 13 degrees Celsius. I took it out in the evening where it was around 5 degrees Celsius and clear out.
- it did rain the night before and the car was exposed to rain for approx 3 hours. I have no indicators to date of water leaks
- when I bought the car new to me from the Porsche dealership a month ago they had replaced the windshield.
- no other glass had moisture on it
Is the moisture normal for a cabriolet?
what may be causing this?
You have water ingress for the windshield to look like that on the inside. Check the area in the rear floor carpets and the front passenger side. The carpets have to be wet somewhere.
A great way to find water leaks is to use the same smoke machine we use for intake leak testing and fill the passenger compartment, then watch the car to see where the smoke emanates from. A decent smoke leak from the inside is where the water is entering from the outside.
As Pete said, you have water getting into the cabin. Keep it out of the rain (or washing) until you've fixed the leak. Take measures NOW to dry the interior (to prevent mold/mildew/smell). Use a fan with windows open. Use those hanging bag dehumidifiers. Drive with the AC on and fan at high (acts as a dehumidifier). Get it dried out ASAP. Hopefully, you won't have to remove the carpets (or other trim) to completely dry it out.

Not sure if I missed something but OP sort of quiet not explaining if there is a wet area?---->If OP hasn't drowned yet, I would suggest locatiing the wet area on floor carpet/etc and follow wetness to a vertical area on interior which should reveal drips
You will need a good amount of light in compartment and take your time scoping it out.
I have done this on 2 of my Landrovers. One leaked from the sunroof drain tube being clogged which leaked down to front passengers footwell.
Second leak was from door seal and leaking onto drivers floor carpet

thanks Groov.
I had a small amount of moisture in the passenger footwell. I took a previous posters advise and help my a/c on high and it dried it out.
I’ll have a buddy assist me by running water along the windshield first and go from there, and follow the drip.

I have experienced something like this under two different sets of conditions.
One was where there was a little bit of snow on the rubber mats in my daily driver that melted, vaporized and condensed on the inside of the windshield overnight. This has actually happened more than once.
The other, very different, event involved a leaking hose leading to the interior heating system in a car that caused a situation making it difficult to clear the windows on startup on a cold evening. The strange thing was I never noticed a smell of glycol. The dealer informed me of the cause and repaired the car.
