    Ive searched tirelessly on the site and google and didnt find anything about the inside of the windscreen fogging up so bad on early mornings.
    Ive tried leaving recirc on, and off, when i turn the car off. Didn't work. Cleaned the window with Maguires thinking it might be due to dirt or something.
    Turning on the a/c doesnt really work, I can only let the car idle for so long before im just wasting petrol.

    Has anyone else had this? Have they fixed it or even worked out what causes it?

    yeh mate have the same issue but i just make sure the the air con is on and the A/C button is on also select the front windscreen for the blower. What i found without the a/c button the aircon doesnt really do much as the a/c button de-humidifies the air which is what gets rid of the fog on the inside of the windscreen.

    i would think maybee check the water drain might not be draining properly leaving some moisture in the car causing the fog

    The demist function with the aircon on should demist the screen in seconds, it does on my VY. Have you checked the air ducts to see if the demist ones are getting enough air and the flaps etc in the ducts are not stuck?

    You may have an issue with your car ? My VE clears within 10 seconds with the a/c and demister on... Have you tried pollution mode before demisting the screen ?

    Ve 2010 SS UTE
    Hey ads18x
    I think the fogging can be a normal thing that happens, like everyone saying use the ac to get rid of, about the condensation, i had the same thing happen to my brand new 2010 ss ute, i think the problem is that as i live in canberra the temp drops at night really quick, i think i had the heater going on the inside while driving then when you get out of the car and go inside for the night the car is warm/hot on the inside and really cold on the outside so as the it cools down inside you get condensation forms on the glass inside the car. After that 1st time i just make sure i dont pull up with a hot interior, just open your windows a bit as you come down the street to vent some hot air.
    Hope this may help
    Cheers

    The fogging happens overnight, so when i hop in my car at 5am the inside of the window has a condensation on it. It may be from the hot air inside the cab forming on the windows but i thought it would go after sitting for 12hrs.

    I tried rain-x that helps heaps but you can see streaks when you get morning/afternoon glare.

    Where are these drains and vents that i can check to make sure they aren't blocked?

    Happened to me a few nights ago, we had freezing rain (literally) and the moisture on the inside of the windscreen was really bad. Aircon cannot remove large amounts of moisture, I used a soft rag to clear the obvious moisture then the aircon to finish the foggy stuff off. Annoying, as you need to clean the inside of the windscreen afterwards or you get those streaks in the sunlight later. The main cause in my case, was I think due to the use of a sun visor which cooled the windscreen down even faster than normal.

    ah k as long as it happens to someone else lol its about 3 or 4 degrees every morning for me. How does the sun visor cool the windscreen, doesnt it just block sun from ur eyes?

    I meant a full windscreen sun shield fold out thingy. It reflects the heat and sunlight as it is designed to do, cooling the interior of the car. The sudden drop in temperature and low temperature combined I think caused my condensation issue. It was the first time I've had it. Was ok today.

    It's always good to find out a concerning issue is shared by others. I wouldn't worry about it, just get a nice clean soft rag to mop up the excess condensation and use the air con to dry the residue up. Back to enjoying the car :)

    I have the same problem in my VS it's driving me insane. Fogged windows everytime in the morning, not just the front though ALL the windows, rear, doors, quarter panels. I do have some kind of issue with my climate control (doesn't blow through correct vents and no heat when the a/c is on)

    Unfortunately the condensation won't clear itself until the car heats up to the temperature it was when you parked it the day before and evaporates all the condensate. 5am is near the coldest time of the day so the worst time for foggy windows. Paper towel or demister with AC on HOT will do it.

    HOT will not do as good a job as a mid range setting with AC ON.

    You also run the risk of cracking the windscreen if you set demist to HOT.

    I get condensation forming on the OUTSIDE of the windscreen but that's because I have my aircon set to arctic 100% of the time. No dramas on the inside. Try cleaning the interior SS with autoglym fast glass... Or better yet, prima clarity if you can get it (order it online) both are great products and have anti-fog agents in them. I stopped using meguiars products a long time ago as o found their durability was woeful and you can get much better products for the same money or less.

    Im getting the same problem with my VS SS. It happens every day. I just bought it. It has a factory fitted sunroof, it shows no signs at all of leaking neither does any of the windscreens rear quarter windows or doors windows. Going out of my mind as to what is wrong. My climate controls (the lower end one with the dials not digital) is playing up I think I have a kinked hose coz the windscreen demister does not work. The vents under the windscreen are abit glogged im going to fire up the air compressor and use the air gun to blow out the leaves and stuff see if that makes a difference. the condensation is really bad. Im thinking maybe the seats and stuff are holding moisture maybe if I swap them??? any one got some advice???

    It gets bloody cold here early in the morning where I live, its been minus 3 to minus 4 degrees C the last few mornings, and my windscreen on my VS is always iced up heaps on the outside, and fogged up heaps on the inside. I just throw some cold water on the outside and run the wipers to clear the ice, then I set the heater to hot with the A/C switched on, and the blower fan set on 2. This easily demists the inside of the car within a minute or two. I also run the rear defogger for 15 minutes or so to help de ice and demist the rear window. If you are already running the A/C with the heater on hot and its not demisting the glass, its probably worth getting the heater and A/C checked out.
    The workshop manuals says that these A/C systems may need periodic regassing every couple of years or so to keep the A/C system working at its best. As mentioned above in another post, the A/C doesnt just cool air, it also removes the moisture from it, or "dries" it, which is why it demists the interior glass so well when its working correctly.

    Sounds as if there is something damp inside the cabin. Carpets aren't damp are they? The only time I have had moisture on the inside of windows is when I have had a 'hot' bird in there on a cold night at the drive in flics...LOL
