MG4 steaming up problem

[bigcads]

Glad that worked for you , i will give it a try later ,

The air flow will always pass through the evaporator even if the AC is switch off .

Im wondering if silicon spray on the door seals might help by creating a better seal ?

My experience this morning was strange as the fogging did not start until 30 - 35 minutes in to driving

I experienced the same issue with fogging until I adjusted the air recycling setting from auto to exclusively use outside air (indicated by the icon with an arrow from outside the car pointing inward). Since making this change, I haven't encountered any further problems with window fogging.

I think it's the auto mode for the air recycle is just too greedy to re-use old air, for it to keep the most heat inside the car, and it's probably not going "through" the AC anymore. Anyhow, after I changed this setting the fogging problem went away completely.

Already did this - still a problem.

Has anyone had the steaming up issue at various times & why have spoken to another owner who has the same issue.

Get a hotel room to shag in rather than your car. That should solve it?

Does it steam up with the air conditioning on?

 

[Roberto 2761]

No Griff it does not steam up with AC on just when no heating is on not all the time though, makes me think damp is getting in somewhere.

 

[Matt x power]

I did but I had switched recirc on by mistake

There's another thread about using AC or not. (Hint: just use it).

Leave the AC on all the time, particularly in Winter, won't do any harm. ??

I admit to being an AC-off person in the summer when it is not too hot but, even then, I have it on when it is raining or the air is damp. I also turn it on at least once a month, to ‘keep it happy’.
In the winter, definitely on all the time.

It's just a pure fact of physics, hot air meets cold air = condensation, simples

There is something particular to MG4.
Other cars do steam up but this car steams up a LOT. Yes Fan helps , yes opening the window helps etc etc but I still want to know from any expert out there why this car steams up so much.

The answer could be actually something good. I think this car has low noise inside the car ie it is pretty air tight. If that is the reason then I'm ok with it.

Will deffo try keeping the Aircon on,
Thanks guys

I especially notice it first thing in the morning when I take wife & daughter to work.

If temperature allows I open at least 1 window sometimes combined with heater/AC which does the trick

What I’ve done also over the years is once a week I give the windows especially inside a good clean ( I use Autoglym Fast Glass ) it doesn’t stop it but it’s not as bad & having dust/smear free windows helps it clear easier.

The MG4 does not fog up nearly as badly as the ZS EV.

There's another thread about using AC or not. (Hint: just use it).

There is another thread specifically about this problem, people talking about water running down the inside of their windows, but I can't find it. If someone else can, I'll merge this in.

I don't use the aircon and I don't have this problem. I think there is either some other setting that needs to be changed, or some cars have an actual fault.

Yes we had this issue on a 60 mile drive home at 10pm. Aircon on, auto mode. Car mists up at rear then front mists up. Turn on windscreen clear button which helps. Then turned off it happens 5 mins later. Rinse and repeat. On one occasion when turning on the screen blower it became worse and i almost had to stop as i couldnt see out. Opening the window to let air in didnt seem to help brake the cycle of misting up neither did switching to manual external air.

I know the external air works as we had a car overtake the other day spewing diesel smoke and you could smell it straight away

We have done hour long or more before without misting but on that particular drive it was out of control.

I have other cars and they dont do this under this scenario

The car absorbs a lot of moisture during manufacture, sitting at the docks and during the sea voyage and can take some time to evaporate especially at this time of the year.

Page 90 of the owner's manual says:
Note: Leaving the system in internal recirculation mode can cause the windscreen to mist. If this
happens, turn on the defrost/demist mode.

Strange one this, with both ZS and MG4 if setting is on air from outside (and set to windscreen fan at 3) then no steaming. Any other setting on the air source (including auto) then they can steam in wet / humid conditions. So keep mine on outside air to windscreen and very rarely had any problem (other than remote heating via app can reset to auto). Others seem to steam up even with air to outside and air at windscreen.
