I have a 98 VT and if you are even slightly damp, in this weather, will condensate almost instantly to the point where you can't see to drive! Opening a window doesn't really help, especially if it's pissing down. is this a trait among Commys? I used to have a VN but don't remember if it was a problem or not. Any solutions? Husband's old Subaru and now Nissan don't do it.

Turn the air conditioning on, simple answer to any foggy vehicle.

Water leaking into the cabin somewhere or a blocked air con drain can cause that to happen.

Any car will fog up pretty instantly from moisture in your damp clothing. The most obvious solution, assuming you have a working one is use the air con with the windscreen demister to initially clear the worst of it, then if you prefer, turn off air con and just leave the screen demister going.
Lol. remember the days in the old cars when you had to have an old rag permanently stored between the screen and dash to wipe the moisture off so you could see? How times change!

VV this. The leak could be around the rear boot or window so check it out with a hose

Ha times haven't changed that much, I still have to use a rag! Which of course makes it worse. The doors do leak when it's raining, I get puddles on the drivers side. So, air con on cold? I usually just put the heater on?

AS others , run the air con, its not just for summer use. In fact it pumps out more air /faster than just the fan. Also it keeps the pump in better nick than if its not running.

Turn the air con on permanently it acts as a dehumidifier, I never turn mine off summer or winter and simply adjust the temperature. Most modern cars are designed to work with the AC always on. I would suggest that you run with the AC on recycle until the car has dried out then put it on fresh from then on.

Open your boot.-Lift the carpet and look down around the spare wheel Becha theres a nice ol puddle of water there. Wuth the 99 commode I suggest a permenant drain hole for the water -about 12mm across is fine.-chances of water flicking up and in are a lot less than the build up in the wheel well THEN -park the car in a garage with a rental dehumidifier in it overnight for a few nights. That will hopefully get the moisture out of the rest of the cabin.

aircon is good to defog the windscreen but put the heater onto the windscreen as well and make sure its on fresh air. replacing wet air with dry air is faster than drying wet air out.
single cab utes would have to be the worse for fogging up. so little cabin room.

do you clean the drain holes on doors and under the bonnet etc from leaves?

Spot on! If you get it cleared with the AC on and then Turn it off it usually just fogs up again on a wet day anyway.

Ha ha. What if its raining? Where are you getting dry air from?

Dry air comes out of the air conditioner. even if it's raining.

That's most of your problem, solve that first. Any AC system has a fight when water that shouldn't be getting inside is getting inside. Leaving AC on permanently merely deals with the symptoms not the cause. But that's often the solution put forward by the non technical minds on here.
There's the answer - you're pushing crap uphill with a pointed stick until the leak is sorted.

If the car has been owned in the past by a heavy smoker I find it tends to make them fog rather badly too. Doesnt hurt to give the inside of the windscreen a good clean with a glass cleaner and then once wiped and dry,rub over with a clean microfibre cloth - just gets any chemicals and dirt off from past owners :)

This non technical mind here, must be because I would have thought fixing leaks would have been really obvious that it really didn't need mentioning, I suggested the AC because there are so many myths and misconceptions on how a AC unit works evidenced by some of the discussion here. Fix the leaks of course but the AC can dry the car out and keep it dry on a daily basis.

Whether or not it is raining is not the issue. It is the relative humidity that is relevant. Condensed water does not usually get to the cabin of a modern car.

The mere male never uses the air con in his commodore. His answer, window down and arm out window. I had to bring it home the other night and being vertically challenged I struggled to see over the steering wheel, it was literally persisting down. Couldn't figure out the air con and no cloth to clear the windscreen. How does he clear the screen? With this bloody hand as is evident by my car's windscreen. Air con is permanently on in mine. This is the first car in a long time that has a heating / cooling system that actually works exceptionally well. Mind you I drive a nissan. The front window demister is always on as well. Learnt the hard way one summer's night when I picked up a car load of sweaty men and the car immediately fogged up. Being warmer I had switched off the demist. Worked a treat when I got over my senior moment and realised what the problem was, short of making all the passengers work or not breathe.

Thanks a lot for all the replies, even if I haven't replied personally to all, you are very helpful. It never occurred to me that it was the leaking that was the cause but it definitely makes sense and I will try and deal with that. Might need some new door seals, I'll check it out. Cheers

Thats exactly the point I was trying to make to tweake. They seem to think air from outside the car is going to be drier than air conditioned and recirced air. I think they changed their post.

And car will fog up. Only needs a bit of sweat and heavy breathing.
