Title: Windscreen froozen on the INSIDE?????
Post by: Davstylee on 16 December 2009, 07:58
Hey people

Now it’s become cold at 6.30 in the morning, I half expect scrapping ice from the windows of my GTI, but not from the inside surely? The temp was showing -4 which when you look at it aint as cold as it’s gonna get this winter.

I have never really experienced this in any of my past cars (Vauxhall Corsa, Citroen Saxo, New Suzuki Swift) I think I got a slight frost on the old Corsa's windscreen when it was proper cold, but not at -4.

The icy patch on the inside was mainly at the very top of the windscreen, and I just wanted to know if this is a common thing or if there is a more serious problem a-foot?? Maybe its me and where I whack on the heated seats and the heating to full blast, maybe I'm building up some condensation or something before I get home, park her up, turn her off and tuck her in for the night? (The car I mean)

Any suggestions???

Has your car ever had its windscreen replaced?

The windscreen on my old golf was replaced and they didnt seal / set it properly.

It used to steam up loads more

So you think it should be something I get checked out? I have a years warranty on the car will this cover it?

My wife's 2006 corsa does this.

I reckon it's because she's got a habit of driving with the blowers off so the car get's condensation/damp build up inside. She also does short journeys so it never gets up to temp.

Personally I like things nice and warm which stops the car from getting damp inside in the winter.

Why don't you dry running the car with the A/C on during the winter? You should run it regularly to stop the compressor seizing up anyway, and also the A/C will remove moisture from the car and aid de-misting.

If you have the car red hot on the drive home & then park up outside i would say it's a good chance that condensation builds up & then freezes up over night.Keep the inside of the screen very clean as this helps.And as above use the air con as well.

Ok I may sound like a right plum here, but I have the duel climate control, so how do I go about getting the AC but keeping the temp hi as there is no dedicated AC button???? In the Swift I had before I could put the temp up to high then hit the AC button and it would greatly help with demisting the car and the such. But in the GTI as I have the duel climate control the way I keep cool is turn the climate control down to low. So if thats the only way to turn the AC on then it would be like sitting in a freezer.

Im not exactly sure what your asking here?

Without trying to teach you how to suck eggs the climate control works by controlling the temperature inside the car, think of it as Climate Control rather than AC. Just increase the temp to the one you want and hot air will blow out and try to maintain the selected temperature (without the need for you to turn it on or off, it will adjust fan speed and level of heat accordingly on its own).

Depending on what year your GTI is you will either have an AC or an ECON button. This basically disabled or enabled the AC which will give you a cooling effect (light ON means its switched OFF just to make things simple . . . ). Id leave it switched off (light ON) as you don't need cooling at this time of year.

Does that clear anything up?

 :undecided:

WTF?  On = off, off = on!  Some engineer that was made redundant at VW had fun programming that logic!  :grin:

If all fails with climate there's always the Ace Ventura, head-out-of-window method.  :laugh:

Post by: AlanD on 16 December 2009, 12:03
lol I know tell me about it.

Having it switched ON means that the AC is turned OFF i.e the default setting is to have AC ON (with me? lol)

BTW this is for my car which has the ECON button (the logic behind it is it means "Economy" so by having it ON your being economic and having the AC OFF thus saving fuel). I can not confirm that its the same with the newer ones which have the AC button, its a pretty safe bet it is thought and all they did was replace the button.

^^^^^^^ ditto.

I'll expect my average MPG to fly through the roof - well, above 25!  :laugh: - now I'm running my A/c tree-hugging, economy style!

:afro:

You save a fortune !

I always run mine with ECON on unless Im sitting in traffic or its just silly hot like over 30 (its all about windows and sunroof down in the summer). Plus you have more power ;) lol

silly hot, like over 30

Hur, hur! 'Silly hot' in the west of Scotland is over 20, mate.  :laugh:

you have more power

Sold!  :nerd:

hahaha ! Going off topic a bit but down south this summer we had some ROASTING days, I remember getting in my car after it had been in the sun and it was reading 37 !!! :shocked:

^^^^^^^ 28 is the best i've seen in sunny Glasgow.

Sorry, OP! back on topic...  :lipsrsealed:

I thought it was press the Econ button to turn the AC off, most stupid thing i have ever seen but hey gotta love the German brain behind that.

So back on topic, should I be worried that my windscreen aint fitted properly or should I stop being a little b!tch and just get on with it?
Title: Re: Windscreen froozen on the INSIDE?????
Post by: AlanD on 16 December 2009, 13:13
I don't think your windscreen isn't fitted properly, its probably just condensation that hasn't escaped and frozen over night.

Run the air con.  It dries the air.

Post by: Davstylee on 16 December 2009, 15:33
Thanks guys, ill stop crying about it and run the AC, or push the econ button so it is switch off which means the AC is on (so damn confussing)
Title: Re: Windscreen froozen on the INSIDE?????
Post by: ub7rm on 16 December 2009, 15:45
Point to note however that the AC won't run if the outside temp is 5Deg C or less.

No A/c for me until about May, then.

I agree with the above.  Ice forms on the a/c evaporator when in use, this then thaws when its turned off.  It is this water vapour which then in turn condenses and freezes on the windscreen.  Nowt to worry about.

You shouldn't get ice on the AC evaporator if its properly charged with gas!!  :cool:

I beg to differ, as after reading this thread today, I ran my a/c it went cold and the temp on the computer read 0.5 (it had been snowing)

Point to note however that the AC won't run if the outside temp is 5Deg C or less.

The air con runs to dry the air at really cold temps.  That author was talking pub.

I refer you all to the instruction manual which states below 5 Deg C the compressor will not run to protect itself from completely freezing up.  Perhaps this changed on later model years (mine is 05) but I can confirm there is no click or change in revs if I try and run mine at low temps.  There isn't two seperate modes of operation for drying and cooling, its one and the same.

You ran the a/c (and presumably turned the temperature down?) when the temp was 0.5 Deg C and cold air came out?! Stone the crows!  :grin:

Post by: AlanD on 17 December 2009, 08:06
Lol just what I thought, it was cold air coming through your vents because it was frezzing outside . . .

Having thought about it, it makes perfect sense. All types of AC equiptment have a form of frost protection in them.
Title: Re: Windscreen froozen on the INSIDE?????
Post by: 2007GTI on 17 December 2009, 09:54
good point, it was freezing outside, that might explain it, but I heard the compressor running!

Title: Re: Windscreen froozen on the INSIDE?????
Post by: ub7rm on 17 December 2009, 11:35
I'm not sure on mine if the fan runs or not but you can hear a loud click as the compressor engages / disengages.  This is what to listen for, it shouldn't happen.  If you watch carefully the revs change a little bit when the AC is switched on.  But below 5 Deg C it shouldn't as the compressor isn't engaged.
