Title: Misty windows
Post by: gwa on 06 October 2008, 19:39:48
This morning (05:15) when I went outside to the car, all windows had dew on the outside which I cleaned off. I got in and the inside was misted up so I started up and put the blowers on full blast with front & rear heated windows. After a few minutes they cleared nicely ...... but after a short while they misted up again and for the next 50 miles I had to have the blowers on to keep the windscreen clear. I know I've got to have the A/C re-gassed, but I checked for leaks and have found none. The carpets are dry cos I cleaned out the tubes (whatever they are called that blocked with leaves). Has anyone got any ideas? what settings should i set the heater controls to? appreciate any help. TIA

Is pollen filter dry?

Also check exhaust vents - in boot, right hand side, little cubby hole. People fill it with crap which prevents airflow.

I am not sure if you have aircon or climate , I have mine on Auto setting set at approx 22 and have no problems .
 If you have the air con on and turn it off when the windows clear in my experience the windowsw very quicly mist up again  :y

In my experience, both of cars and coaches it happens more when windows need a clean ( car i bought saturday does the same and i must clean them but they need to be dry and warm!)
Just a thought!!

Well its not easy by torchlight, but it felt dry. When I got back indoors my hand was really black so I presume its dirty. For the sake of a fiver or so I'll just change it, the cars probably never had a replacement.

Would it hurt to whip it out tonight and replace tomorrow PM when I get home from work?

No it wont hurt it's held in with two clips  but BE CAREFUL they are fragile, also while your there have a look in the bottom of the space to make sure the drain in the bottom isn't blocked up with leaves and other crud.

The manual says:
Air recirculation system
The a ir recirculation system prevents the
entry of outside air and the air in the
passenger compartment is circulated.
Automatic a ir circulation mode 3
Press button t briefly twice within one
second. t appears on the d isplay .
Air circulation is automatically activated as
soon as the system detects polluting gases
from the outside air. The circuit is
controlled by an air quality sensor.
To deactivate electronic a ir circulation:
press button t again.
At outside temperatures below 5 °C the
duration of the air circulation mode is
limited. This prevents the windows from
misting up. Switch to manual air circulation
as necessary.

In your dreams!

Around £11 + VAT tradeclub. Being facelift, it must be the more expensive carbon type, not the cheaper ones for prefacelift.

Ah, well that was a few weeks until TheBoy cleaned it out and I hosed it. Thanks for the 'fragile' tip.  :y

I must admit, and it seems a common problem on these cars, but i have never known a car to mist up like these do, when its raining !!! - and the A/C system seems a bit 'vague' - i think it would be VERY helpful if one of you highly knowledgeable people could explain how to stop misting up and how to PROPERLY operate the A/C  system for the de-misting use of - very much appreciated  :y :y :y

Mine is fine on auto - mists up when on eco - but if you pop it back on auto it demists very quickly.

Have tried all sorts of anti fog with not a lot of joy

Just my 2p worth

Thanks

well i can tell you how i use it... leave it on auto and adjust the temp accordingly to the temp you want to acheave, when cold starting i dont turn it on to HI, leave on desired temp and cc will manage the temp as heat or whatever you select becomes available, HI is flat out fans reguardless of heat available so with cold engine all you get is cold hair drier. Same with LO but the with flat out ac.so that can take a phew minutes to get cold giving luke warm air for a minut or2. therfor as i said select the temp you want to aceave and let the cc do the rest.

think of it as a heatrer and air con, the climate controle just blends the 2 to give the precise temp you feel comfy in. the fans will blow harder and softer depending on the urgency/temp differential you set. so if you get in the car on a hot day and you set 21 temp the fans will blow hard to cool the cabin to acheave that temp asap and will gradually carm the draft as it gets near the desired temp.

you may feal the fans are too strong on average and there is a soft ware update via tech 2(see THE BOY or Mark DTM/Hotel 21 north of boarder) to calm them down

ECO turns of the ac pump and therefore the de humidifier(?) tosave a tea spoon of fuel but the car will mist up sharpish usually.

the omega is very good with cabin climate generally so any excessive misting on auto with eco off indicates a problem tbh... usually exccesive damp somewhere or the ac is broke

Thats about all i know about that, i am  sure others will advise further...

Do you find much of a diffeernce in fuel economy with eco on or off?  I think i see about 10% difference (better in eco obviously)

would be suprised if its that much tbh, but the downside is misting dirty windows and buggering about opening windows to clear the screen, not worth the agro...imho :-/

ac pump is bottom right pulley on aux belt, lift bonnet and see if the 4 knobs on the end are turning when the ac is on and engine running, this means pump clutch is engaged and should be giving cold air. make sure eco is not selected.

If not working please dont use quick fitup or halfords. use a specialist who knows what he is doing. Ie check for leaks evac and regas to 950(iirc) insuring oil in the system.

With clean pollen filter, working scuttle drain and clear vents they do not mist up.

Mine sometimes steams up when 4 sweaty males get in on a cold damp day like today ... but it clears within a couple of minutes with the demist selectioin, then return to auto and it remains lovely an clear  :y :y :y :y

Past experience shows that CC off and/or recirculation on will cause a great deal of misting in damp/cold conditions.

Is pollen filter dry?

Also check exhaust vents - in boot, right hand side, little cubby hole. People fill it with crap which prevents airflow.

oops!!! ::) ::)

Okey dokey. I've changed the pollen filter and removed the 5ltr oil can from the cubby hole, like mr richierich 'Oooops'. So I'll see how things go and I'll try the advice from chrisgixer. Meanwhile the readings are,
Consumption 29.2 mpg
Trip Cons 4.4 gal
Speed 50mph
Trip Distance 131.2
So its starting to look good  ;D ;D ;D ;D ;D ;D

Check that the recirculation flap is not stuck down (or the linkage damaged). I had this once. You should hear it move when you swich the recirculation off/on.
