Boxster misting up

[miroku]

OK this may be me doing something wrong! (Not unusual) Since the weather has turned damp/cold my Boxster seems to suffer from misting windows/screen more than any previous cars.
I have tried air con off/on with little effect. Anyone else suffer this? Any clues as to action to take gratefully received.....thanks

First check that the carpets and bottom of the doors are dry. If the drains aren't clear then water can get in and will show up in these places, it's important to clear them as there's a lot of electronic gubbins under the passenger seat - most people only find out after it's too late.

Thanks both. Carpets seem dry and in fact the car was in the local OPC recently and I noticed that drain holes were clear. However, I will double check tomorrow. Thanks for the quick replies.

Are you sure air con is working. Mine demists very quickly with it on. It only mists up with hard top on, never with soft top.

[miroku]

Thanks for the help. I have played around with the various settings and things do seem to have improved. Certainly no dampness in the car at all. So, I guess the drain holes are ok. Only had this car a few months so still learning! Age makes one slower you know! On that note I wonder if I am the oldest Boxster driver on here? Just so you don't have to guess......pension kicks in next year.

I find that my Cayman S is very susceptable to changes in atmospheric conditions. Mists up like hell some days and is fine on others.

Oh, and you are most definately older than me - but not by a lot

Awaits Clarksonesque booting.

Yes you need to ensure only the fans pointing towards the screen are on (i.e. fans towards you and feet are off) to get it to demist. Also you have a demist button on the dash that will turn the fan and temp to full to demist the screen. The only time I have to use this is going through tunnels in the winter when the windows mist up instantly.

Nothing like early retirement... with a Porsche!

Add 10 Maersk! Will a zimmer fit in the boot of a Boxster?

I'm only a year and a bit behind you!

[miroku]

Looks as if I am still in the lead then! I am thinking that perhaps this is not a good thing.

They all do this - nothing to be worried about - just something to get used to! As someone else said - just use the windscreen demister button and you'll need the aircon on when it's damp / cold.

I essence there is a huge open drain area on each side, where the roof meets the body behind the front windows / doors. This is where a chunk of the roof pivots around when folding, but it's like an open pocket and not sealed off from the inner cabin ...

Not specifically familiar with Boxster, but if there is a 'recirculate' button on the aircon / heater, make sure this is set to OFF i.e. not recirculating the cabin air but allowing in fresh air from outside.

I think the re-circulation function will switch itself off after 15mn.

Isn't that completely the wrong advice?

If re-circ is on, the cabin air is continually being processed through the air-con system getting drier each time, whereas with re-circ off its always having to deal with a new batch of damp air...

[miroku]

Thanks for all of the advice. I have tried various combinations of settings and mostly resolved the issue. Still mists up when the weather is particularly wet. Best combination seems to be: airflow set to feet/screen. Certainly if the face vents are open misting is much worse.So thanks again.
On another topic. Went to the OPC 911 preview in Leicester last night. Very impressed. After much discussion the wife insists we are not going to sell the house to fund a new 911. Ungrateful or what !!
