    I thought heated windscreens were designed to de-ice the screen and then go off not keep it de-fogged like the rear one does, you have a blower for that on the front.

    Martino on my Tiguan the heated screen automatically comes on when you put the max demist on, it turns itself off when it senses it’s cleared the screen.

    If I switch the max demist off the heated screen goes off.

    Is yours linked to the demist/aircon?

    A pro tip for stopping your windows fogging up, don’t use aircon. Most of the fog is trace refrigerant in the system being blown onto the glass.

    Turn your aircon off and clean your windows thoroughly and they will fog up much less and not need cleaning as often.

    During those couple of days in the summer when aircon is actually needed, set it to feet and forward vents and not the screen. After use keep it off the screen for a good while to allow any gas to clear the system.

    Had my current car 3 years and 1 month, used aircon 2 or 3 times and cleaned my windows maybe every 3 months.

    I use the aircon all the time misting up is never a problem.
    Been doing the same since aircon was added to cars.

    Me too, never mists up on any car I’ve had with Aircon. I use rainex on the outside and that stops bug spatter in summer and keeps the ice off in winter.

    Air conditioning actually helps to reduce fogging, as it dehumidifies the interior of the car – just adjust the temperature accordingly for the time of year. I run my AC in my car almost permanently; in summer it keeps me cool, in winter it keeps me warm, without fogging up or me needing to ‘crack a window’. Trace refrigerant has nothing to do with it (shouldn’t be leaking anyway) and it is only cold when it is in the system anyway.

    The only downside to air conditioning is that it draws power, therefore stealing some from the engine and also using marginally more fuel. For me, it’s a trade-off that I am comfortable with.

    OP – my heated windscreen goes off automatically after around 1-2 minutes in my car, and this is normal. The idea is that it clears the screener from ice/frosting/whatever, but you then adjust your heater in the car to keep the windscreen clear (and I’d recommend trying having your air conditioning activated, but the temperature set higher, perhaps around 21-22 degrees). Just keep it on a low fan setting, but set to blow onto the windscreen.

    I always had an issue with work cars getting in after another driver and they are all fogged up as they have used aircon during the day but temp changes for night shift caused moisture.

    The choice is use aircon for a quick demist or use normal vents and sit for ages until the fog clears.

    I had to do the latter as aircon gives me a bad throat.

    Aircon creates moisture due to temperature difference creating condensation.
