Hi all,

Wondering if any body elses C-HRs windows most up with the slightest bit of downpour.

The auto window demist works well but as soon as I put it on different mode the windows start to mist.

Never known a car to most up as quick with a slight change in air temp/ rain.

No leaks from Windows or Windows left open.

Have you got the aircon on? I find it mists up quicker when the aircon is off.

Takes a while to find the correct balance of controls- heated this or that, which vents to open, speed of fan etc. but once found can be left as set. ...or maybe just an occasional tweak. I found it quicker to demist than my RAV4- and that was pretty quick.

Without the AC on mists quickly indeed.
I'm still thinking there is a leak somewhere.
But haven't found any real damp carpet.
Maybe it comes through the doors. There are several holes in the door that link to the inside.

My point exactly, demists fine. It's that fact that it mists up so quickly. Never known a car like it, apart from one which was physically damp inside.

No leaks present or damp anywhere.

does sound like a leak, you could try airing it out on a sunny day, windows open a boot open

I rarely use my ac, but in this car it is a must.

As soon as it starts raining within minutes the car starts fogging up.

Al the cars I had were the same. And I think it's normal, unless you have air leak somewhere. If it's warm and raining, the rain cools the window. Same when I drive to underground parking - it's much warmer (and damper) than outside, so moisture from your breath starts condensing on windows

I did a test this morning. I haven't used the AC for a couple of days.
I set the system to auto. The windscreen started to fog up.
I turned the system off, the misting was still "growing".
I turned on recirculation (while the system was off). The misting became less (and disappeared).
Turned off recirculation (with the system) off, fogging appeared again.
Setting the system to auto intensified the misting.

It almost seems like there is moist or water in the air inlet since nothing happens when the car is in recirculation mode.
I haven't looked yet where the outside air intake is located. Does anyone know?

How do you turn recirculation on without turning AC on?
Recirculation mode is always on in my car, but I don't think it does anything while AC is off. And also it doesn't help to clear the due from windows while AC is off. Auto or Windshield defogger has to be turned on to demist windows.

Guys, when it is a bit damp or misty you will get misty windows unless you have the air con on and temp of the the interior higher than what is outside, simples

I never had damp windows in my previous cars when it started raining. Assuming my clothes are dry.
Just leaving the ventilation system on auto and AC of would do the trick.

You can turn off the AC when in recirculation mode. Or in techstream you can turn off the automatic recirculation when switching the AC on.

Today I added extra sound insulation to my rear door (did just one yet). There is a transparent plastic sheet which is supposed to be glued over al the gaps in the door. But mine was loose on 5 different points. This created 2 oppertunities for water vapour to get into the car. I have sealed them up now. I expect this might be one of the problems.

Can you make a DIY for removing C-HR doorpanels? A layer of insulation is what i also want to do.

Check your aircon gas too. My aircon is dead and making funny noises now after 5k miles. Guess ive been breathing in refrigerant which would explain excruciating headaches and misty windows. My passengers also complained of watery eyes.
