Windscreen foggy

masterboy123

Hi,
Whenever I leave my job after work in the evening, the front windscreen is all foggy from inside the car. It takes atleast 3 minutes of hot air to get a clear view from windscreen.
What can be done to resolve this problem?

You have moisture in your car. A wet carpet perhaps ? Find the source of the wet patch first, seal the leak, then dry out with de-humidifier if possible.

corktina

if you have aircon, turn it on....keep the vent open all the time and the fan turned on. If it's still foggy, damp is getting in somewhere, check to see if it's wet under the carpets.

Buy a moisture trap in your local euro shop. They look like this:



Sick it in the pocket of the door and it'll absorb the moisture for you.

Just use your hand to clear a circle about the size of a dinner plate in front of you and drive off, no bother! It's all you need to see!


It's what an awful lot of people seem to do in the mornings! They just seem to not be able to sit in the car for 2-3 mins while the fan does its job.

Unless there is a leak it shouldn't be that bad. Do you have the recirculating air button turned on or off?

Did this yesterday and almost had an accident.

I would highly recommend not to drive until atleast 80% of windscreen is fully clear. Dont risk your lives and others!!

The recirculating air button is off. I use only the hot blow air and on rear side there is heated windscreen which works very well.

Also check your pollen filter isn't gunked up with dirt, if it's blocked it will contribute to condensation on window.

This is the solution:

Fog can't form on a spotlessly clean windscreen.

or cat litter in a sock does the same.

If you can park the car facing south or southwesterly, towards whatever little bit of sun is shining, it helps. There's still another problem to be addressed though.

+1. And if you can get to it easily it's the cheapest fix mentioned yet. Just take it out and see the difference,

cletus

You need to solve the problem, rather than just mask the symptoms. First place to start, as said above is the pollen/cabin filter, as this is one of the more common causes of condensation.

keano25

At this time of year its not unusual to get this, so before we start ripping cars apart think have you left a window down, worn wet clothes in the car etc.

Any easy cure is to leave the doors open when its a dry day, that usually drys a car out.

If its still the same in a week then start at the pollen filters etc.

Spook_ie

Check any drains from the front scuttle are clear of leaves etc. The air enters the car here and if moisture is trapped there causes foggy windscreens

Toots

Give your windscreen a good clean. The dirtier it is, the more fogged up it'll get. My sister drives a 99 ford ka and it would get very badly fogged up, the inside of the windows would nearly be dripping wet. She had trouble finding one of those little dehumidifier packs, so what she did was got a small tupperware lunchbox and filled it with salt. She leaves it on the dashboard with the lid off when she's not in the car, then when she's driving she puts the lid back on and pops it in the glove compartment. The salt absorbs the moisture in the same way as those little dehumidifier tubs do.

I usually wind down the windows for the last couple of hundred metres before parking the car for the night. Recirculates the air nicely and gets the moist air of people breathing in the car out before sealing it up for the night. Usually results in a fog free windscreen in the morning.

Doesn't really work that well when it is raining though :-(

I used to have terrible issues with moisture/ fog on the inside of my windscreen.It used to take ages to clear and was a right pain in the morning. I could not find any leaks etc so after a bit of research I went with silica filled moisture absorbing bags from Amazon.

I have a 1.5kg bag back and front by windscreen.

Would highly recommend them , windows have been clear so far this winter.

Wish I had found them earlier.

I would agree with other posters, change or at least clean the pollen filter. If you search online there is likely to be details for you make of car. I worked for me

ikeano29

Change pollen filter if air is weak and as importantant is to clean your window, use hot water and viniger, a cloth and newspaper to finish.
Will be perfect

Clean your windscreen with something other than a sweaty paw. Don't use recirc unless slurry or a filthy diesel ahead of you. Use aircon if available. Change cabin air filter once a year even if dealer claims to have serviced your car.


If you still have problems you have a leak. Or as vw would call it, a water feature.

This is what I got. They are free UK delivery so went with parcel motel.


For me they work a treat. I was originally going to buy one of those heaters that you plug into the cigarette lighter. Glad I didn't in the end.

Someone said to me before to switch from the one that automatically comes on when you turn on the heat. I think that means turn the switch to recirculated air.

I'm still doing that when clearing the windscreen, turning over from the default switch to the other one. Is this correct?

L1011

Recirculation will massively increase the moisture very rapidly. Theres no reason to use it except external pollution really

kirving

Or if outside is an an extreme temperature of course. If the car has automatic climate control, there should also be a humidity sensor to regulate how much outside/internal air is recirculated. My car will blow cold, low humidity air on the windscreen if the engine is not yet up to temperature when I press the "clear windscreen" button.

Since any recently modern air-con pump should only run when it deems necessary (I would strongly think), I leave my air-con on the entire time to keep the humidity at the correct level. Never have an issue really with fogged windows.

Noccy_Mondy

Them dehumidifier bag things are good, but they don't last too long before getting full with water. Most other solutions have been mentioned. Keep the windscreen spotless, there is nothing for the condensation to stick to then.

The heated windscreen in my focus was replaced with a non heated one at some stage. I'm half tempted to smash it and get the proper one put back in.
