Every time I turn ON or OFF my air con / heating, the air automatically switches to FRESH mode, and I want to keep it on RECIRC. I don't want outside air coming in. But the car seems to insist on it, and I have to manually switch it back to RECIRC.

When I turn on my car, I find it is always in FRESH mode. I suspect, as soon as I turn off the engine, it automatically goes into FRESH mode, meaning it is letting outside air into the car the whole time it is unattended.

I really don't like this. During winter months (as it is for me right now) I enter my car and find all my glass is fogged up. This isn't your standard mist, which is just tiny globules of water so fine it looks like mist. What I'm seeing on my glass is big globules of water, so thick that even my demister can't get rid of it. I have to wipe it with a towel (which I don't always have on me), and even then my screen is not clear.

I don't want outside moisture getting in. Is there a way to disable the auto FRESH switching?

If it helps, I have i30 Elite with climate control.

[Shambles]

If I hit the "Auto" on my climate control, it sometimes switches to recirc and sometimes does not. Seems to depend on the outside temperature.

Never bothered me to be honest as I normally use the manual temp/speed/direction/airsource buttons.

However, I do believe there may be some combination of praying and monkey magic that affects what happens with CC, though it might just be about the defogging logic. Try a search on defogging - you might be lucky.

On my old Accent you could tap the air con buttons in a particular set order and from memory you tapped 1 button twice at the end of the sequence to confirm the mode.

I don't have the handbook with me to see if this is the same for the i30 but it may have something similar.

Hi lostn,

Your heavy misting worries me.. sounds like your car has got really wet inside at some stage  Is this possible?

[Just Rick]

the heavy dew/mist inside the car like dazz said would have me worried, is the car kept our over night or is it garaged because this can make a difference,especially if it is parked outside on very cold nights.I used to have this happen in an older car I used to own in melbourne in the winter months,It was always parked outside,made the problem lesser by covering the car with a heavy blanket

[constipated]

Check the manual. My FD i30 has an option to turn off the pre-programmed fuzzy logic within the climate control such as insisting when you press the front defogging button, that it switches to outside air. Also, depending on the temperature you set, it would choose recirculate vs outside air.

I have switched that off and now have full manual mode.

It entails a set routine of button pushes. All in the manual.

i thought the same thing dazz. check the rear wheel well, rear quarter panels and floor for moisture/water, especially the rear wheel well and quarter panels for 'tide marks', on next really dry day leave everything open for the whole day with the car in the sun...

my wheel well had filled with water at some stage, i think the tail light wiring grommet may not have been installed correctly, one was a touch funny when i did the light mod (all light up under brakes and park lights).

you dont want water in the car, it evaporates, then condenses above the roof lining and sits there causing rust in the roof where the roof stays are...

I don't see how. Though this heavy misting only started recently. But that could just be the weather (I'm in Melbourne, Australia).

I haven't cleaned the interior other than a wet cloth to wipe the dashboard. I don't have a leak in the car, so I don't know how it could have gotten wet inside. I'm quite sure it's to do with the air venting. It's not the only car that keeps switching into fresh air mode. I've seen cars go from recirc to fresh by itself, but never the other way around.

It's parked outside... But here's the thing. All my cars have been parked outside, and I've never had a misting problem this bad with any of them. But all of them had mechanical switches (not buttons) for air circulation which can't be changed automatically by the car. In fact, I never even needed to demist them, because the mist was always on the outside not the inside.

I'm unfortunately not very mechanically minded... Do I need to take apart pieces of the car to check those things, or is it a check on the outside? It does rain a lot at the moment. Not going to be a dry or sunny day for a long time.

Changing the air source to RECIRC will not stop your misting problem. For starters the car is not air tight. It will always "leak".

Notwithstanding, even on FRESH, there must be a draw of the air to get the air from outside to inside the car, it won't just flow by itself.

If the air is moist, as it is in Melbourne, and the temperature drops to below the dew point, which it will over winter, then the water will condense, and if there is something to bond to, such as glass, which will be colder than the inside air, then you will get what you currently have.

Don't blame the climate control for doing what it is designed to do, blame Melbourne's weather.

I'm on the north west coast of Tassie which has similar weather to Melbourne.

Has been a few year since we parked our i30 outside overnight (and ours was an FD) 

I don't recall the inside of the windows ending up with more than a light mist on the inside even when a thick frost on the outside.

I have only heard of this after someone has got their carpets really wet due to a leak or something. You don't have to disassemble anything to check. Just feel your carpets and inspect low points in your boot etc.. like the spare wheel well etc..

Leaving the car on recirculating can make the driver drowsy (that is one of the reasons it defaults to fresh) and sometimes I find fresh clears misting quicker anyway

G'day,

I wonder if you have the main setting set to windscreen. I had a play with the good wife's car, and when the A/C was set to blow out the passengers section, it would turn on and off on recirc mode, turn it to windscreen and it wouldn't. This would explain why I couldn't recall it ever being a problem in mine (and perhaps the misting, if you run cold air onto the windscreen it will fog up on the outside necessitating you to use the windscreen wiper to clear.

I always have my A/C on recirc mode, you never know when some old (or not so old) car will blow smoke in your face and recirc keeps it out.

Yes when you live in constant inclement weather Dazz  you don't really notice that it is in fact inclement weather  ,But everyone watching the weather does notice it when UM gets the inclement weather up his way

That's funny, Dazz.  I've never heard of widespread flooding, cyclones, drought in Tassie, but it is common place in Queensland. 

Remember, Tassie isn't cold, Canada is cold.

  with the exception of the "drought" bit in Tassie...

and your point is  Qld weather great one day brilliant the next,the floods,drought and cyclones are just for light entertainment,for when they get bored with the good weather 

[eye30]

Both my i30's got and still get condensation on the front window in cooler weather.

I resolved it, to a point, by making sure the vent to the window was closed before I turned off the engine.  I press the vent to the footwell.

Good idea Lester 

But can you try and keep on topic please ... We were talking about the lousy, inclement Queensland weather ..
