I've noticed that on cold mornings (like this morning) the standard heater settings are insufficient to keep the windows mist free. I garage my car overnight and so start off fine but within a few miles start to mist up. I can clear things by turning up the fans but it is a bit noisy and as soon as I turn down again the mist comes back. I've never had this in a car before (but I've never had a car this big). Previously I've just been able to leave cars set to 20C all year round.

Is this just a problem with large cars or might I have a fault?

RR are sealed tight so no ventilation other than heating system. On really damp mornings it pays to leave the front & rear screen heaters on a while. Use the program button until screen clears then when you hit the button to resume climate control the heaters will stay on. Make sure you leave the A/C on at all times so that both orange lights on heating control are illuminated.

+1 for keeping the a/c on..

there's loads of moisture about because of the heavy rain we've had so until the air gets dryer do the above..

Yes and its good policy to always have the two amber lights on (auto) ensuring the electrics are kept nice and dry at all times.

Another thing is to ensure the air-recirculation isn't accidentally activated as this really increases interior misting.

And also ensure your interior glass is spotlessly clean and free from dirt / grease. A good glass polish (not spray) is best for this. It really helps!

Thinking about it, could your pollen filter be damp as that would give the misting you describe? Si. <This is my name.

I think I am doing pretty much everything suggested - always leave the a/c on and front/rear screens on auto setting, and definitely coming on because orange lights on and front/rear screens clear. Also OCD about cleaning.

Pollen filter is an interesting theory. The only way I can see it getting unduly wet is if I'm squirting water in somehow when washing. Is there a risk I might be doing this (my wash routine is pressure wash, snowfoam, wash then rinse with pressure washing again, so three good soakings every week - and, as it happens, yesterday? I'll have to keep an eye on whether it happens more after "wash day"

Not sure about the L405, but the L322's pollen filter is a doddle to remove and check.

You could, as a check, remove yours and put it in the house overnight.

Your pressure washer theory is a sound one. A few minutes to cross it off the list would be worth it, in my view. Si. <This is my name.

Also, check your boot well for water - this will increase condensation

 Where do you go after one of these . . . ?

Can anyone tell me where the pollen filter lives?

Just picking on from the "keep AC on at all times" post.

I have been at loggerheads with SWMBO for ages now as she insists on turning the AC off as soon as she gets in the car because "AC makes it cold and I want heat" - Solution crank up the temperature dials to full and full heater. I have tried to explain the concept of climate control but to no avail. Her reasoning being that the frost icon on the ac button means that it is for cold air only!

Completely agree that turning the A/C off just results in a lot of dry hot air in the car which is uncomfortable. Can one of the experts please clarify so that I may show her this post and put this argument to bed?

dear deranged wife , please read this,

http://www.airconditioningforcars.co.uk/ACpage02.htm

Get her to read it and remember its the A/C that takes the clammy moisture out of the air. Air Conditioning NOT Air Cooling. Repeat that as you are driving over and over until she understands....

PS: Tell her keeping it on could save you hundreds in repairs that would otherwise have been spent on her

Well I suspect the problem was over enthusisatic car washing. Similar conditions this morning and no misting whatsoever. I guess that as air is drawn through pollen filters constantly they dry out quite quickly.

Question is - where is the ventilation system air drawn in? Is it via the air intakes at the top of each front wing or elsewhere?
