Anyone help with a lot of condensation in the cabin when I get back tot he car and start her up first thing. It goes away with the aircon and screen blowers, looks dry in 4-5 minutes, then I park up, come back to the car and same again. It is wet/damp and cold. But I didn't suffer from this in my previous car and keep aircon on at all times

Its a 2015 991.1 GTS by the way and I have cleaned the car recently with a pressure washer/foam etc

 

 

Make sure you are not recirculating the cabin air, and that the AC drain is not clogged.

 

 

Thanks, all

I will check today

 

Okay and update. The problem is still here....

I drove the car yesterday, clear when I got in, clear with the journey, 8 miles, then park up and it mists up inside, when I return to the car. I had fortunately booked the car in to Porsche to review the problem. A clear day, car had no mist or condensation when I started her up or drove 25 miles to Bristol. I park up on a dry day and within 20 minutes misted up again. Porsche check the aircon heater etc, etc, check the drainage all okay. A full test for over a morning. They run it on circulation, heat etc for 20 minutes and say all looks okay now. The car evidently didn't mist up, it was fine when I got there. I drive home and just checked, guess what... Bl**dy condensation in the car.

The condensation is a very fine mist, that removes the visibility completely, usually but not always on all he windows including doors. Any ideas, its very frustrating

 

 

The dealership checked all over for any areas of dampness and leaks and said non could be found, they ran the car for 20 mins, test drove etc. They took the under tray off checked all of the drainage and it was fine, the condenser taking water out and it coming through and out the drain hole normally.

I think there must be something happening with the air con and heating in some way, next time it's dry I will take it out with the air con off and see what happens. Raining again at the moment :-(

 

 

 

I think it has always been there but I did pressure wash the car (carefully and normally) in the first week, usually clean once a week, with good weather

 

Okay more information but no answers :-(

Didn't drive the car during the week, didn't notice any condensation. Drove the car on a wet day, no condensation when getting in and none whilst driving, air-con off. Park up and come back....condensation....

Today, lovely day, dry and the cat seemed fine condensation gone. Put aircon back on, drive about 15 miles park up for 2 hours, come back, okay no signs of condensation. drive 15 miles back, all good, it would seem. popped out to check and the screen is covered in condensation :-(

I have never experienced this on other cars, I am worried about internal damp, it seems okay and the interior feels and smells dry, any ideas much appreciated. It will go back to the dealer but I suspect it will come back no better...

 

OK, IMO the question is was it there before you pressure washed it or not. Assuming it started happening after there is a chance that the water found a way into some place and is still there. It will then eventually dry out, but may take a while. My daughter had unfortunate event when she unknowingly pressed a remote button in her purse (stupid design by Honda) and her brand new at that time Pilot opened up the roof w/o her knowing. It it was on a rainy night. Next day we cleaned it all up and dried everywhere as much as possible, however the condensation kept coming back for a week until I put it in my garage and dried it all with fans, heat gun (very carefully) and couple of hair dryers for 48 hours moving them around and trying to reach everywhere I could. Since then the moisture/condensation completely gone. And BTW the dealer (Honda in that case) was pretty useless.

 

Interesting, it hasn't been washed by me for 2 weeks now, but has been ungaraged. the odd thing is to comes back after running and leaving standing in the dry for a few hours
