Title: Can you help me please - Inside window problem
Post by: Jeff15 on January 13, 2022, 11:18:41 AM
This morning after getting in the car the inside of the windscreen would not clear, tried everything I could think of but I could not clear the screen. Please help.

What demisting selections had you made and what  was the outside temperature?

Have you pressed the front screen  demist button? This Automatically  sets everything to the optimum setting  - heat, maximum fan, air conditioning  on (for dehumidifying) and the most suitable vents.  Its a bit noisier than normal,and maybe not the most fuel efficient setting  but it works for me. Better than fiddling around trying to find the best  settings individually.

I needed the car early today. The outside temp was 2C. The windscreen was frosty. I started the car and pressed the demist button and the heated rear window and mirrors button. Within 4 minutes the car was clear.

I've had this once and it took an absolute age to clear with the front screen demist button on. I'm talking 10 minutes minimum here. In the other Hondas I've owned it took a couple of minutes usually.

I've only had this on one occasion though. Bloody annoying but I wonder if it's a quirk of this particular model. I should add that the screen was frozen on the outside although I had scraped this off.

I reckon it's from your own breath. Don't breath while in the car and you'll have no more trouble.   :D

Seriously though, if you open the windows while demisting it does help to dry the interior air.

I've found on the Jazz I need a microfibre cloth to wipe the inside of the windscreen first thing.

The air alone isn't enough to shift heavy interior mist on the windscreen, but after wiping a lot of it up with the cloth the air can clear the rest ok.

I think the big windscreen and angle of it in the Jazz might mean it's more likely to suffer interior mist.

Bought one ages ago :

https://www.amazon.co.uk/gp/product/B0017K69MA/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1

I still find turning off the heater for 5 minutes stops interior misting. For some strange reason it starts blowing air as soon as you power up. Hold your hand over the dash top vent, it surprised me albeit a modest trickle, it's enough.

This initial air is likely cold and damp and mists the inside screen quite effectively.

Give the inside of your windscreen a clean with a good quality glass polish - Autoglym etc.
This will remove any dirt/contaminates that the damp air is condensing on.

Which reminds me I must do my car as it is shockingly dirty on the inside.  :'(

The real question is why dont Honda offer a heated windscreen as an option? A heated windscreen not only clears any ice on the outside but rapidly clears any condensation on the inside. Its not like it is new technology either, heated windscreens have been around for decades.
Title: Re: Can you help me please - Inside window problem
Post by: Kremmen on January 13, 2022, 02:37:42 PM
The inside of mine is squeaky clean but it still used to mist up on cold damp mornings if I didn't initially kill the airflow. That misting was so bad that I got a warning that the safety systems had turned off.

I don't use anything on mine except for a good scrubbing with a microfibre. I hate anything that leaves a residue.

With a telescopic handle,  Tesco and The Range sometimes have them as well - can reach the whole screen from drivers seat and they collapse down to fit in door pocket.

Halfords sell this one

Glad to feel not alone with internal misting of the windscreen. Very frosty this morning and took a long time to get the ice off the exterior, but amazed at how much condensation there was inside the windscreen, most of it frozen. The front screen demist is powerful but the internal condensation is worrying for a new car. The last time I had that problem was with a ten year old Land Rover!
Title: Re: Can you help me please - Inside window problem
Post by: sportse on January 13, 2022, 05:29:18 PM
I'll try switching off the climate control when I'm defrosting the windows, as I have lots of early starts.

On several other cars I've had, there was no air at all through the system until the car engine had reached a certain temperature - maybe the Jazz problem is caused by it putting air on the screen when cold?
Title: Re: Can you help me please - Inside window problem
Post by: peteo48 on January 13, 2022, 05:34:57 PM
I had a VW Golf with this problem but the Mk4 Jazz definitely seems also to have an issue. I'm fortunate in that I rarely have to go out early but I'd be seriously hacked off if I was getting up for work when the weather was cold. What's strange is the demist button seems to have a very slow effect. In other cars you could see the mist retreating as the air rises from the vents.

I've also noticed that the inside of the screen can be badly misted first thing but, as the temperature rises that interior misting also goes away.

Garages are for motorbikes and other boys toys not suitable for in the lounge,  cars are plenty waterproof enough to stay outside....  Let's face it most modern garages are still designed for a 1960 size Mini.. or an original Fiat 500....

I'll say it again: if you open the windows or doors, (not while you are moving natch!) the mist on the glass will clear faster.

Hmmm... Our garage is spacious enough to store our Jazz, two bicycles, in winter the patio furniture, a large cupboard measuring 1.65 m by 60 cm, the (artificial) Christmas tree (48 weeks a year), and a lot of unnamed junk. Oh, there is also running water, cold and warm.
And then we can still walk around the Jazz without any problems and the doors and tailgate can also open normally.
So our Jazz is inside when it's not in use. Also safer... right?

And guess what... no windscreen problems... :D

If you have a garage, then why not use it??
Many garages around our way are simply filled with 'Junk'
My Jazz is put in the garage every night, not just to keep it warm, but also for better security.
There are too many stories of keyless cars having their remotes controls cloned, to steal cars when left on the drive.
And of course it doesn't steam up!!!

i have a window vacuum, which I use in the house to clean condensation from the inside of windows in the mornings (sometimes) and the bathroom window which can get steamed up.  I have recently used this on the inside of the car windows, early in the morning.  However, on a few occasions there has been ice on the inside of the windscreen.......

No car thief would risk losing their credibility by stealing a Jazz,  I am more than happy to leave our cars on the drive, although a Civic is a more tempting target than a Jazz.  To be honest any condensation on the windscreen of our ( non-hybrid ) cars is gone in less than 30 seconds.   Unless you put a dehumidifier in the garage with you car it is likely to 'sweat' anyway, and encourage more corrosion than leaving it outside.  Anyway the only time our cars get cleaned is by mother natures free carwash...

My issue could be that my car is parked in a garage that is warmer than outside.

In any case, pressing the left side heater button to turn it off for about 5 minutes works well on cold damp mornings.

Post by: sportse on January 14, 2022, 08:36:39 AM
Looks to be a design flaw unfortunately.

I was parked outside and the temperature was minus 2 when I started the car:

- first I tried switching off the climate control, but the engine shut down quite quickly. It meant there would be minimal heat when I was leaving.

- then I tried turning the climate control back on, but setting the air direction to the footwell instead of the screen. Unfortunately even in the footwell position there is air coming out of the windscreen vents which misted up the inside of the previously clear windscreen!

Ill have to stick with the microfibre cloth.

( I do have a karcher window vacuum that I use for inside the house on winter days, but its too fiddly to try and get the windscreen cleared. )

I've never had any problem like this with my Crosstar. I park it in the garage but always leave the driver's window open a couple of inches for ventilation and the windows are always clear when I leave, maybe it's an issue which only occurs on the saloon model? On occasions where it's been left outside and the windows are misted the climate system clears them in a minute or so (with a window open) and in extreme conditions the front screen heater makes short work of it.

Probably water trapped in the aircon system,  I routinely turn off the aircon for last few miles to clear moisture out of the evaporator radiator.

Water on inside of house windows  :o  You need one of these..... they  recover 'latent heat of evaporation' back from water vapour in the air, and actually add heat to the house,  they also keep walls and ceilings dry and improve the insulation properties, also dryer air heats up more quickly.   Keep bedclothes feeling nice and crisp as well,  not damps and chilly feeling.  Can I ask if you had retrofit cavity insulation put in, a few people I know did and their house was damp afterwards, but no reduction in energy bills

Garage is between 2 houses so the temp in there never gets as cold as outside even though the garage door and rear is ventilated. Plus I do have a descicant dehumidifier running that does suck out damp air.

I think the above is right that there is a design issue as it shouldn't blow cold damp outside air straight onto the screen before the engine has warmed up a bit which doesn't seem to take long.

i Went out at 7:10 this morning, -1 degrees. Put power on, pressed front & rear demist & recirculate buttons. Got out to scrape the windscreen and there was already a clear patch at the bottom. It just needed a bit of scraping to help it along. Clear in a couple of minutes.

Garage is between 2 houses so the temp in there never gets as cold as outside even though the garage door and rear is ventilated. Plus I do have a descicant dehumidifier running that does suck out damp air.

Our spacious garage (6 by 4 meters) is located under an apartment block. The access to the garages has an (automatic) door and each garage has its own door. So quite shielded from the winter outside.
Only once in 15 years the water in the garage had to be shut off because the temperature in the garage approached 0C. This was during extreme winter weather in January 2013 with night temperatures outside of -20C and lower. During the day max. -6 or -7C for a longer period. Normally, the temperature in the garage in winter remains around +7 to +10C.
In addition, the building has a ventilation system, separate for the garages, effective and with gas detection.

The garage is almost ideal. Only one complaint: if you drive the car in dirty, it won't come out clean...

With my Jazz, it's always parked outside - at the moment in sub zero temperatures.

Unfortunately air conditioning doesn't work when the outside temperature is below 3-5 degrees I believe, so you are left with just air coming out of the vents.

I was surprised how quickly the engine shut off with the climate control turned off - the coolant was nowhere near hot enough to even give heat to help melt the ice/demist the screen.

Perhaps the warm up cycle for the engine just looks at the temperature of the catalytic converter for emissions rather than for heating.

Fortunately when I leave I haven't got far to the main road and 30mph, lights and radio gets the engine going and it heats up in no time.

Under EV mode though no engine to heat the air will be a problem.

Yes.

For all the misgivings around EVs - poor charging infrastructure, range anxiety, high purchase cost - the ability to get instant heat is a blessing. On the Nissan Leaf (prob the same with others) you can get all the heating systems going before you get into the car so this windscreen fogging is a non issue. You can do this whilst your car is plugged in so using your house electricity.

I've seen this work - it's impressive.

This shouldnt work according to the manuals of every car Ive owned

Except it works brilliantly in the Jazz! Many thanks.

I followed the above and had the clearest inside windscreen ever.

I noticed when moving off, I put the climate control into auto and it immediately turned off the blower. So looks like we need to manually control the system to get rid of inside mist.

Hardly a plus for EV seeing we do not get much really cold weather in UK, and considering what cold weather does to EV range..

I had a feeling manual intervention might be needed.

I stopped using the automatic mode on our Mk3 due to the lack of air flow until it was warmed up. Similarly, ours mists up more than our CRV did, I wonder if water is being trapped as someone has mentioned and this is being vaporised into the cabin.
Lastly, if I turned off the AC on the CRV, it would blow damp air in for a while, I found turning it off at a time I wasn't in a rush allowed enough time to vent it and it then behaved OK when not using AC.

I think I made it clear that there are still many drawbacks - it's why I didn't get one - but the preheating ability is a genuine plus point.

What you have to consider is that most EV journeys aren't long enough for range to be an issue, provided you can charge up at home. When we use ours for journeys of say under 100 miles round trip we can start with a decent level of charge and have the heating on as much as we want knowing that we can "fill up" again once back home so range isn't really a worry. If you're mainly doing long motorway trips then you're better off with a hybrid at present (like the Jazz).

Presumably a fully electric car has instant heat available.

Yes.

For all the misgivings around EVs - poor charging infrastructure, range anxiety, high purchase cost - the ability to get instant heat is a blessing. On the Nissan Leaf (prob the same with others) you can get all the heating systems going before you get into the car so this windscreen fogging is a non issue. You can do this whilst your car is plugged in so using your house electricity.

I've seen this work - it's impressive.

From 10/11/21 to 13/01/22 - just over 2 months - I did 299 miles. I reckon a weekly or fortnightly charge would do me on a low range EV - the problem for me is a few longer journeys we make. This is why, for me, charging infrastructure is the biggie. I spent a lot of time looking at zap map and noting the very high percentage of chargers that were out of service. I don't want that stress in my life. If we had 2 cars, one would definitely be an EV.

I had probably the thickest front windscreen ice today, despite that I only had a light bit of misting inside by the time I was leaving.

The procedure with full defrost buttons and recirculating air as soon as you start the car seems to be the best way.

I've done a couple of journeys recently from a cold start and my one off misting issue hasn't occurred again.

I wonder if a cold snap following warmer weather is responsible for this excess misting.

I think it does as our MK3 starts to mist internally at the end of a sunny but cold day.
It was about - 2C this morning, ice on the glass was sprayed, clearing the ice and I couldn't see any condensation. However, as soon in the car and switching on the engine the condensation set in...
Bizarrely, on the windscreen, it seems to set, like a film which a microfiber cloth works hards to remove and leaves streaks. I'm wondering if it's had some form of treatment added to the screen like an anti mist which is in fact causing issues.

I used to have the same thing - I think it's mist turning to ice, so when wiped inside it doesn't clear off easily.

Using the front defrost when starting the car has stopped this happening to me.

Today it was only one quick wipe to clear the light mist on the top part of the inside windscreen

Any ice /  moisture left on the evaporator coils in the aircon system when engine is turned off will come back out when the system is turned back on, and will be carried by the airflow onto the screen.  I normally turn the aircon off about a miles before I get home, this allows evaporator to dry off,  so the air coming out when restarted will have no more moisture than ambient air.  If you leave system in 'auto' all the time this problem will always be there,  personally i never use auto because I hate the way the system works with the vents it chooses and the way it almost turns the fan off.

I'm guilty of using Auto all the time as the easy option.

Just noticed that on the new HR-V a Heated Windscreen is standard on Advance & Advance Style models. Hopefully it will become an option on the Jazz in a future model year update - really simplifies cold morning starts and quickly eliminates any condensation.

It's not a heated windscreen overall, its heated elements in the windscreen for the wiper area and the area up the drivers side pillar where any ice/snow would be pushed by the wiper stroke.

Same here, all year round, never had any issues.
