Whilst it isn't unusual with A/C (for reasons I can explain if asked! - Don't want to bore you all to death!), When you turn on the engine after leaving the car, the windows get steamed up on the inside (If the A/C is on) and take quite a while to clear in the EOS...

My question is "Does anyone else find this?"

It just seems particularly bad in the EOS, so I was wondering if everyone had noticed it!! (It is also somewhat climate dependent)...

Thanks

Not something I have noticed. But do you have climatronic or just standard A/C, may be something to do with that??

Cheers

 

[SiJ2000]

Mine's just standard....

My aircon is just standard to. also I have noticed how bad the misting up is and how slow the aircon is to clear it my old golf was never this slow.

But I think the answer has something to do with it being semi climatronic because the aircon unit does not kick in until the car is blowing the temperature stated on the dial.

Thats what i think if anyone knows better please correct me.

Technically, I think the evaporator coil is absorbing the water and not draining off for some reason. Maybe the evaporator drain is pumped, therefore the coil will remain wet once the engine is off... This is relatively normal for AC, but it does seem excessive in the EOS. I believe this is also an issue in the Passat and Jetta...

One way to prove this is simply to leave the AC on cold, turn off the AC and let the fans run without AC to dry out the coil. Next time you start the AC it won't have the moisture!

I will do some testing and report back, but it is not a fault, so nothing is fixable, I just wondered if it was supposed to be this bad, evidently so!!

Hi Guys,

I have found this on our EOS and previous cars but here's a tip for you.....

Before switching off next time, try moving the direction contoller so that the airflow is not on the windscreen. You should find that upon restarting the car, the windscreen will not mist up as the air is being directed elsewhere.

Just my two penneth...

 

[SiJ2000]

That's a very true suggestion and practical

My car is climatronic, always garaged, and I've never had any problems. Mind you I had an R32, standard a/c, out for a couple of days and rang the dealer the next morning as I noticed a large puddle of water under the car. After checking with techs the salesman said it was the a/c.

I have climatronic too... and this morning for the first time noticed this problem. Windscreen misted very heavily as soon as I turned the car on... then took an age to clear!

Not great, but I can live with it!

 

[GOgg]

We had a frost this morning and the misting inside was considerable and as Adamber says it takes an age to clear. When its icy it takes about 5-10min to clear, that's a pain.

 

[adamber]

Up to 10mins... that is a pain in the ar$e!

I hate wiping the window as it always leaves marks... only like using the blowers... huff!

 

[GOgg]

Since you got the winter pack, the pain should not be as bad, switch on the bum warmers.

Being an ex Ford owner, I don't understand why all Manufacturers don't include the 'quick clear windscreen' feature that's been around for decades.

You get tiny elements in the windscreen that clear all mist in seconds - and when it's icy you have a clear windscreen within a minute or two.

All air conditioning systems in automobils have a recirculation button. In the summer when cooling the car, the "recirc" button is in to recirculate air inside the car for max cooling. In winter the ''recirc" button in out to bring air in from the outside. In my Eos there are four buttons in the center of the console, the upper, left side button looks like an arrow making a u-turn, that is the recirc button. I believe that when you have the button out, your misting problmes will be over.

 

[Scooby Doo]

Sorry but I don't use the recirc function and I have the same problems with misting - hadn't really pinned it down to the aircon and not convinced it's only with that. I just find it's a very misty car!

 

[adamber]

Thats an interesting point, I dont use the recirc button much, but it may make sence when trying to clear the window - the air in the car will be getting less "damp" as the blowers are on... so recirc'ing that rather than dampper air from outside my speed things up!

Thanks - I will give it a try when I next have the problem and let you know!

 

[GOgg]

In my other cars the best way to clear misting of the windows is to switch the A/C on and also recirc. However in the winter 'cause of the ambient temperature that don't work.
You need to let the A/C do the temperature change for you i.e. warm the air then blow onto the screen. Thats what the windscreen demist button does. Its just that it takes a long time to do it.

As for Fords quick clear screens they are poor and not worth the money. They clear the ice quickly corrrect, but the elements in the screen have a tendency to fail (lost 4 within 3y from new) and you are left with strips of ice anyway. Don't recommend VW puting them in unless the element failures are fixed.

 

[SiJ2000]

I'm not sure recirc would help clear it in this instance because the dampness is on the evaporator coils, so would still get blown out when the fans get turned on (usually when evaporator has been run recently...)

It's only a pain because I go to give someone a lift, turn on the engine and low and behold, can't drive for 5 mins! LOL

Some things to consider. . . .

The climatronic unit does not blow ari on the screen for a few seconds when it is first turned on (it blows it at your feet) - this was the same in the passat I had for four years and gave back three years ago.

When it is freezing outside the ambient air is almost dry (significantly below then it IS dry) - the frost on the car is the moisture that was in the air.

If the screen mists up and does not clear with the aircon on demist (and not on econ) then either you have a blocked pollen filter or a faulty a/c compressor or possibly a leak allowing water into the car.

I have a similar problem on the Honda and it probably relates to the first - due for 112.5k service next week.

I don't have that luxury! I have the semi auto normal one!
