Hi all,

I feel bad even bringing this up considering some of the bigger issues other have had with their CM but I was curious is anyone else was having a problem with the windows constantly and consistently getting foggy? Whenever I have to drive with the windows up I always have to de-fog.

Does anyone know what this usually indicative of? I live in NY where the average temp has been about 42-47 so far this winter. I keep the inside temp at about 72-75 except when very cold I will crank up the heat until comfortable and then shut it down.

Thanks

 

We don't have this problem in our cars (Clubman and Roadster). We have the auto A/C and always use it in full auto mode. This way the A/C is always enabled and the car uses it to get rid of the excess humidity.

 

I have thst issue in my clubman...but then again my windows use to leak took dealer over a year to repair..

 

Like pjv1k says, are your carpets and/or floor mats really wet? Do you have a sunroof that could be leaking somewhere that you can't see? Is there water under the trunk floor where the spare wheel would be?

 

Turn recirculate off and the AC on.

Recirculate off will pull in fresh crisp air from the outside instead of reprocessing the humid air from inside the vehicle.
AC on will dehumidify the air from outside.

My windshield and side windows do get foggy when it's snowing, but it clears quickly once everything is adjusted as above and left on auto mode.

 

You know what? I have that exact same problem. I live in NY as well and once the time got cold, my windows, (especially the rear windows) constently fog up.

 

The above should solve the symptoms. Just check around for any moisture...just to be safe. After the gym or a rain event my CM will fog up unless I do the above.

 

I have the same issue with car fogging up. My other 3 cars no problem.

 

Guys, u may have a blocked water drain for the condenser.

my cms all4 does not fog up, i have the "standard" HVAC controls

my dad's cms all4 does fog up the windows, he has the auto-climate control and it seems to default to recirculation "ON" ... manually turning the recirc off clears the windows

Yep! Recirc = Off and A/C = On to defog

 

With any car in the winter if the heat is on recirculated air must be off. Fastest way to clear it up is with the ac. If you have the controls set for heat by your feet, enough comes out by the windshield to keep it clear. I run about 66 or 68 temp. and it stays clear.

 

my 2011 and 2012 CM both have this issue. fan off, two of us in car, set on fresh air. Car starts fogging.

 

You are sitting there in the car breathing, and thus producing humid air. Turn on the fan and the A/C and the heat. Direct the air flow to the windshield.

The A/C will condense the moisture out of the air, and the heater will warm up the now dry air.

Alternative is to stop breathing, but that has bad side effects.

 

You may want to check the type of product that you are cleaning your windows with. Windex has always caused my windows to "fog" up pretty bad.

 

Turn the auto climate control on....and make sure the snowflake button is ON. This keeps the air conditioned and keeps the fogging away. I used to turn the snowflake off in colder weather, and I got the fogging windows.

 

Definitely no water in the matts or anywhere else. I also keep my can in the garage so it's not usually sitting in the rain. I usually always keep the air on a pass thru and not the cabin recirculate. It's just weird that I always have to put the air on the or else the fog builds up. I figured this would happen more in the MC hardtop since the cabin is smaller and body heat/ breathing would have more of an effect. But I didn't really have that issue much. Only in the CM. Strange.

 

if i turn the fan control all the way down (off) i get no airflow at all

i keep the fan on 1 click up and the airflow turned all the way clockwise so the air is directed to all the vents ... the fan makes no noise when set like this and the windows do not fog

It doesn't have to be a small cabin. Interior fogging up of the windshield happens in my MINI Clubman and also in my wife's Honda CR-V which is noticeably larger.

 

Ditto. I learned thru fogging windows that with the fan all the way on "low" it seems to allow NO airflow (unlike every other car I've owned).

So, if I'm driving with the windows closed, I always have the fan on at least one notch up on the dial with no fogging problems.

Worked like a charm!

 

I'm in NJ and as soon as it started to get cold, the windows fogged badly. They also fog VERY badly when I'm drinking coffee and it's cold out.

I've never owned a car that fogged this bad in the last 50 years. I assume the real reason is the windows are thinner than my previous US built cars/trucks. Maybe they conduct the outside temp and interior moist warmth condenses quickly.

I LOVE my Mini Countryman S A4, so for the slight inconvenience, I don't mind. I run the defrost as needed. (recirc on/off makes no diff at all)
