Cayman 981 GT4 windows misting in heavy rain

I need some help if possible please. I got caught out in a rather heavy downpour yesterday afternoon and although I had the climate control set on 19°C, when I came to a stop at a set of traffic lights the windscreen, side windows and rear screen misted up almost immediately. I hit the demist button for the front and rear screens immediately which cleared the front and rear screens quite quickly but when I turned them off and went back to 19°C the windows misted up again when I came to a stop at a junction.
Has anyone else had this happen or have any idea of how to stop this happening? I did a quick Google search and a lot of forums are suggesting water ingress and wet carpets, albeit on older cars, but my carpets are bone dry and there's definitely no water ingress anywhere in the car.
All the glass in the car has been cleaned with GTechniq glass cleaner on a regular basis.
Hopefully someone will have a solution?
Cheers,
Andy

Maybe you're right that 19°C is probably a little too low especially with the lower ambient temps over the weekend and I should have had the climate set on 21°C-22°C. As far as I'm aware the ventilation system is the same across all 981 Cayman variants. Next time I get caught out in a downpour I'll maker sure the climate is set a couple °C higher.GeeDog said:I wonder if 19c is a bit cool in heavy rain and with these low ambient temps we've been having? I wonder if it's as simple as try a couple of degrees higher and see...? My 981S has been sitting at 21-22c recently. Is it the same ventilation system on the GT4?

I could be wrong but surly there has to be some sort of effect with the mid mounted (in cabin) engine.
either that or need to get down to Porsche with some urgency lol

Definitely….will do.
Are you sure that your aircon is actually switched-on and working? Normally it should be more than adequate to prevent any moisture build-up.
What happens if you put the system on recirculation?
As suggested, increasing the temperature should help. In the cooler weather I normally set it at 21 deg C for comfort.

Thinking about it now I may have inadvertantly switched the aircon off as I think the red light was illuminated on the A/C Off button which means A/C is off. I honestly can't remember now.
Think it's probably best to leave it on Auto/Sync and in future have the temp sync'd at 21°C or higher if it's raining. I'll also have to try recirc too and see what happens when that's switched on.
Cheers for the tips and help.

Chaps, thanks for your responses and note to self….read the manual!!
Cheers,

I'm sure my 981 GTS was the same but I could be mis-remembering! Apologies. Porsche like to mess about with this stuff between models but the manuals aren't always correct either...

Thanks for all the tips, pointers and help and thanks to ADH Independent Porsche Specialists in Rayne, Essex for re-gassing the A/C in my car.
