defogging your windows?

[bigt1888]

mixture of cold air blower and window slightly open works for me

but the recirculator setting makes it impossible to clear so i avoid this

[zazen999]

Cold blower as when it is misted - the last thing I want is the chuffing windows open.

[bigt1888]

Oh I love that, I love it (just wouldn't dare)

I answered my own question: today I had cold blower, no heat and window open a crack (1cm)

Worked a treat, no fog at all and no hot sweats either

if you really want to annoy him you could do what my wife does to me.. leave the seat base in the highest position possible and as im 6ft5 it guarantees i bang my head on the way in off the door surround everytime.......im sure she does it on purpose

My screen mists up terribly every time I get in my van from out of the rain. I find that setting the heater to cold with window slightly open and making sure the recirculation button is not on is the way to go.

[taff]

mine isn't newfangled, so it's window open and air blowing, whether it's cold or hot.

lol

I have a Smart, and OH is 6' tall and 20 stone. I can't make it much harder for him, wouldn't be fair

Not sure why misting would make you prefer just adding cold air, rather than some warmish air coming in and the moisture getting out? Perhaps I just don't get what you mean?
All other things being equal, you get less misting with a window a bit open. (better still 2 windows both slightly open 1/4 inch is enough)

My better half's motor (the car is not the surprise one) is awful for condensation and a real pain when it's really frosty because it ices up inside as well. It gets the dehumidifier in for an hour or so every so often to suck out any excess moisture and that helps immensely

My better half's motor ... is awful for condensation

Can you drill any holes to improve ventilation? This chap advises it: YouTube - Defogging Windows

[green thing]

some people just don't get it
It's called ventilation
it should be included in the driving test how to use your heater and demist your car before driving off.
some people drive around with there vision obscured without any regard for the safety of other road users pedestrians or cyclists

if you just have fresh air form outside your window will not steam up
all you do is turn the heat down to a comfortable level
but keep the air coming in

All cars have to have air vents built in somewhere so you don't need to drive around with the windows open

my neighbour use to have a smart car and had problems with condensation it was traced to leak on the windscreen letting in water into the car behind the dashboard then running down
under carpets

No car is air tight.

Try breaking down on a winter's day and see how quickly your car gets cold inside.

Mist/fog on the inside of the window is down to moisture in the air coming into contact with a cold surface (the same principal as condensation on house windows). If you had a controlled environment with two identical cars, and used the aircon on one car and just blowers on the other - I guarantee the one with the aircon on will demist quicker as aircon removes the moisture from the air (hence why contact lenses 'dry out' for passengers).

If you use the aircon with the windows open you are effectively trying to remove the moisture from the world.

Some cars do it better than others.

If your car has aircon, normally when you put the blowers on full blast, it activates the aircon.

I'm a hot air man, can't be doing with driving a cold vehicle, with the window open. bbbbrrrrrr.

Air con means COLD air.
Heater on screen warms the screen, but it also warms the air inside the vehicle. Warmer air will 'hold' more moisture. When warm wet air hits the cold screen, the air cools rapidly, and sheds its moisture as condensation. People (inside the vehicle) produce atmospheric dampness (from breath if no other reason).
If you warm the screen BUT also open windows a little, it really does produce the best result.
On a frosty morning warm air to the screen is essential, so 'cold' versions only work down to zero C.
Heat doesn't only leave the car via ventilation. Metal conducts heat very efffectively, and even if the car WAS air-tight (which wouldn't help breathing much), it would still cool down to ambient temperature if there was no incoming heat.
It isn't 'heater OR open the window, it is 'balance of heating and ventilation' (a phrase I see every working day, because it is one of the routine recommendations on a house survey). The hotter you keep the inside of your car, the more essential it will be to let the warm wet air get OUT! Even in a downpour, if you have the heater on, you will get rid of dampness better by opening the window A LITTLE! (1cm is normally enough)

I'm ok then - mine is 'Climate Control!'

Get me!!!!

[HeyWayne]

Air con means COLD air.

Not strictly true.

I have mine on 19 degrees.
