Hi i have not had my elite for long but every time i use it all the windows mist up and even with everything blowing full it does not clear completly. The only thing i can do is drive around with the window open slightly. There are no leaks that i can see and the filter is clean. Any ideas please.

Two main possibilities:
1. Rain leak. Check for dampness in the carpets around the doors. There is supposed to be a plastic sheet inside the door to deflect any water away from the cabin. If the door trim has ever been off, it might not be sealed or might not be there at all. Check also rubber door seals
2. Leaking heater matrix. check for dampness in the carpets under the driver and passenger side. If it is leaking coolant you should be able to feel dampness somewhere or even smell it as it will have coolant in it. Check also to see coolant level in the engine bay.
-
It might also suggest that the Air con isn't working? Mine mists up a little when i have the Eco button pressed but always clears with the AC on.
-
Also, check the drivers side cubby hole in the boot is clear - this is the exhaust vent for the cabin, and if its blocked with rags/CDs/tools/junk, the car doesn't refresh the air too well.
-
Make sure the recycle button isn't on
-
...and make sure the passenger side scuttle is clear (below the pollen filter) or you're puling in air over a puddle ;)
-
Main reason for 'misting up' is people have the 'ECO' button on so as to save money, you may gain 1mpg but you can't see the way forward due to the 'mist'. :o
The 'air-con' controls the temperture and dries the incoming air ie reducing 'misty windows'. :y

What year please....

This one rings true with my estate. When I have the cover pulled fully over any luggage to keep out prying eyes etc, the windows mist up quite badly. However with the cover pushed back, no problem with misting up. I can only conclude that the cabin air cannot escape past the cover and out through the vents at the rear of the car. :y
-
I have an estate which also used to mist up. Never tried pulling back the rear cover but that could be a good idea. I also found that cleaning the glass really well then appling an Anti Mist (available from Halfuds) helps greatly although can produce minimal smearing. :y
-
Be aware that the earlier face lifts occasionaly have a problem where teh climate sits on re-circ......pressing the re-circ button to cycl it through the settings sorts it out!
-
It does appear to be a common problem on Omega estates. Caused me all sort of headaches when i first had mine in winter >:(

What year please....

check pollen filter isnt damp
check the trim on top of the pollen filter is seated properly
as said check boot cubby hole isnt full of things blocking air escaping.
make sure windows are very clean
I dont normally need to use air con to demist. :y

Iused to have surprise misting up. Read up on the forum to check under the scuttle, and was gobsmacked to find water to a depth of about 5" under the pollen filter housing. I used a pressure hose on the drain hole location and it all suddenly "glugged away"no trouble since. In fact the car interior is now, 2 weeks later much dryer.What a score!! :y :y :y

this is very common, out of sight out of mind. when I bought mine at the end of october it was misting up a bit, then i found this forum and read about the skuttle drains. Checked them and there was an 1" or so of water standing in there. I make it a habbit of checking them every week or so (not really an issue this time of year as no leaves on trees) but always worth a look.

seems to be a common prob on these - hmphh

Just thinking about this a with the cold temps that we have been having well under 4c am i right in thinking that the AC will not work below this temp and if so, if the windows mist up there would be no was of demising them is that right.

You are correct regarding A/C and low temps but the screen vents will still clear the screen :)

True. If the AC runs at sub-zero temperatures the evaporator will just ice up rather than extract water as condensation and let it drain off (in actual fact the expansion valve will probably just shut it down anyway), so it has no benefit.
Having said that, if the air temperature is well below zero, the air is normally very dry anyway, and becomes (relatively) drier when it is heated, so it is effective at clearing glass without the AC.

:y :y I see
Thanks

Hi all, i have looked into the drain under the skuttle and yes it was blocked. I have cleared it out but still i have the misting problem.
I have noticed something new.... only a couple of times has this happened but when i start the car from cold the heater blower will not work no matter what is pressed on the dashboard, even when the car had got to a good working temp the fans dont come on. It is all lite up and on, i can hear the ducts moving when i press different buttons just no blower, then maybe 10 mins later it all kicks in and starts blowing. But it does not stop the misting unless i have the window open a bit. Also
not having a car with air con before when i tried the other day to put it on LO it blew cold but it was not really that cold well i didnt think so anyway... could i have a problem with the gas or something could this relate to the misting problem??
Cheers Andrew
Yes filter changed

Did you renew the pollen filter :question
-
You can get to the fan if you pull the glove box out - I had the wiring connector break (no idea why) so cable tied the plug and socket together
-
Got the same problem in my estate but no noticeable dampness anywhere else.
I noticed that there's almost no air being blown onto the screen regardless of ECC controls. The fan works fine so I'm presuming it's a problem with at least the stepper-controlled demister valve? There's doesn't seem to be any response to resetting the valves (by holding AUTO and OFF in for 5 secs) and all fuses are intact.
Is it a duff control board behind the control buttons, or a hidden fuse or something? Help appreciated please.
