I got in my car tonight and after starting the engine the windows fogged completly up.
It then took 10 minutes to clear the windows. :(
This has happed a few times but not very often. If I use the defrost and the air-con needs gassing could this be the problem? The air-con seems to work but it's hard to tell when it's so damn cold to begin with :D
-
Have you used Rain-X? That used to be a constant problem when I used it before.
-
I've not used rain-x, are you saying that it's a bad product?
-
its ok but, if it happens again, cycle through the recirc function on the climate
-
So it's the outside air that causes this? The inside of the car was cold and I was hot from recently exercising...maybe that had something to do with it? :o

Yep awful, all it gave me was constant fogging up. It stopped the rain a little bit but, I couldn't tell the difference because I couldn't see nothing due to the windows fogging up.

Yup .. your warm body moisture condenses on the cold screen .. simple law of physics .. :)
You then put the blowers on and once the air is warm the screen gets heated and the condensation evaporates ...
If the recirc is stuck on the humidity level inside the car continues to rise as you are not "changing" the air.
If the vents in the boot (in locker on right hand side) are blocked this has the same effect as constant recirc .. the air cannot be changed and the humidity rises.
High humidity measn more moisture means it is easier for condensation to occur on cold surfaces. As you drive along your front windscreen is always getting cold due to the airflow over it.
Lower the humidity with fresh air and the condensation will rapidly decrease .. which is why opening a window makes such a big difference .. :

Courtesy of MarksDTMField Remedy: 1417
Subject: Electronic air conditioning ECC - Window fogging after engine start
Models: Engines:
Option:
Omega-B 2000...2002 All ECC
Complaint: The windscreen will suddenly start to become fogged at inner side caused due to increasing humidity inside the car.
Cause: At outside temperatures of 5 ° C and less with a battery which is not fully charged, recirculation flap is switching to recirculation mode if the supply voltage drops below 9 V for short time.
Production: As of VIN W0L0VBF6921013332 a corrective action has been introduced in production.
Remedy:
In case of customer complaints see the following instruction. This failure can be identified when the problem disappears after switching-on and off the air recirculation function. Procedure: First switch on Auto mode, switch-on the air recirculation by pressing the button A once (3 round arrows will be indicated, without "A" in the middle). Now the ECC will recognize the correct flap position. Wait 1-2 s and then switch-off the air recirculation by pressing the button A again.
FunctionalGroup: D - Heating/Ventilation/Air conditioning
Complaint Group: 13 - No/Poor Function
Trouble Code: Non

Wow, thanks for the precise feedback, I'm tempted to put my shoes on and try it right now :D

Could be your windscreen skuttle well drains are blocked, reach in below the climate control filter and if you,ve got a small lake there fish around and unblock the drain hole. There's some "how to do's" on the Forum hope this helps :y :y :y
-
hmmm, noted. Thanks Rob. :y

Suggests that a climate firmware update might resolve the issue. Certainly mine did it once or twice in the early days. Don't think I've had the updated firmware do it.

Am I right in thinking that the air-con won't work below 3 degrees C as well? This won't help when you're trying to demist windows

It doesn't fix it, helps a bit but can still occur occasionaly

Air con works at all temperatures ... what happens below 3 C is the compressor stops providing cold fluid... this is to prevent the evaporator icing up. The theory is that the outside air at 3 C is cold enough to provide any cool air you may want inside ..... :)
Think about it .. at 3C you probably want the air con to provide warm air anyway !!!
Conditioned air is just that ... conditioned .. be it hot, cold or warm .. it is air that is "conditioned " to what you want.
As an "extra" .. cold air can hold little moisture ... so air at 3C is pretty "dry" and does not need the "drying" effect the air con system gives to warm moist air in the summer.

Use the bedroom for......'exercise', then no more steamed up windows. Seemples ;) ;D ;D ;D :y
