because air con is one of the best ways to clear your screens.

As above. Turn one notch the other way and it won't come on :)

aaaaah, thanks for clearing that up. I didnt want to ask the question incase it was a daft one

i may sound daft asking this i have never had aircon so i could only see it making the air even colder. so why would it clear the screen quicker.

Basically, you are equalising the temperatures on the inside and outside when you use the cold AC to clear the screen.

The only other alternative is to use the de-mist on full blast and roast to death.

Also, when you are demisting, as opposed to defrosting, you will be bringing in de-humidified air which will assist the demisting.

Likewise if you have the air-con on when it's a wet day, there is far less chance of the windows steaming up.
