Windows Fogging Up

[garrymossley]

can someone help, i have a real problem of my winscreen fogging up , there dosnt appear to be any damp/water ingress, when the weather has turned colder and damper its been a real pain, i had this last year in the winter and resulted in using holts anti fog, it seemed to work but got quite smeary when the sun shone through the screen making it difficult to see out, can anyone advise as to why this is happening, ive heard of lots of people with this same problem, the front screen blowers is just not powerful enough to clear it , it can take 10 minites to clear with a lot of wiping too

 

A huge headache :unsure:

 

the vehicle is a late 2001 model

 

Thanks all

Are you using any water as the prime suspect for that is the heater matrix

[Guest vr6galaxy]

Use the AC it removes the moisture from the air and aids demisting :unsure: AC isnt just for use on the odd hot days we get! :o

Thanks for your replys on the fogging, what i forgot to mention is that the condensation is there before entering the car, i do use the air con to clear the screen and also wiping at the same time. if you just wanna go out quickly youve no chance needs demisting first, not safe to drive off straight away, carnt see!

 

Thanks again

 

Any remedies welcome :o

If you think the cause of the problem is due to the high moisture content in the car try and find the cause and dry it out, check under the carpets for damp? check the passenger side foot well! common cause of moisture ingress is the rear washer hose joint! make sure all the windows are shut tight, no holes tears in the door seals? befoe you reach your destination switch off the AC but keep the heater on, give the condensors time to dry off! and from my experience wiping only encourages misting up! make sure the screen is spotless, use the anti fog and dont wipe again, your removeing the coating and spreading all sorts of crap around on the screen! plus you have a damp cloth sitting there adding to you problem!

if you have access to a dehumidifier stick that in the car for an hour or two and see if that helps?

Garry, I have had exactly the same problem as yourself with my 1997 Sharan and found it to be due to leaves blocking the drain channel under the bonnet. When blocked the water diverts to the passenger side of the car and collects down the side of the front strut. I syphoned the water out several times and it seems to have cleared itself, there must be a drain in the bottonm of here which is now clear. Also if you do not clear the water away it builds up to the level of the pollen filter which draws water into the car when you put the heater fan on. This causes the condensation and the passenger footwell to get wet. I have contacted VW but they will not help me because of the age of the vehicle. I hope this is of help to you.

I get this in summer and winter, and it is worse after using the air con. The car also gets steamed up when left parked in sun on some cooler winter days.

 

I posted this question when I first got my car, and the answer was that it seemed to be a common issue with the air con where moisture from previous use remained in the system so that when you next used the car, some moist air initially came out of the blowers.

 

I don't have a damp car, blocked drains or leaves etc, so I am resolved to accepting it as a design issue

There is hit the search button and enter scuttle drains, a few posts on the topic will pop up :huh:

And splash shield on the pollen filter too.

Any remedies welcome :(

Thanks guys for your help

you know this fogging windscreen is really baffeling, last night the winscreen was really bad with the condensation,now tonight ive just been to check and the winscreen is perfectly clear of condensation, yesterday it had been raining today its been dry really strange, and also the neighbours have a sharan and yesterday theirs was fogged up , and tonight their screen is clear from condensation like mine

 

bizzare isnt it :huh:

[Masked Marauder]

When it rains the rain runs down the windscreen and runs off behind the scuttle panel where it splashes onto the pollen filter.

 

Any fresh air drawn into the car is pulled through the pollen filter and the moisture enters the car. Later models were fitted with a pollen filter holder that has a splash shield fitted.

i keep a window wiper sqeegy in my car, the sort window cleaners use to remove the water. this wipes the screen clear better than a cloth.

This time of year can be a real pain for fogging WS. I find if the car has been stood in the afternoon & you get a shower then bright sun it can be a real pain. Problem is that AC doesn't kick-in went temp below 5C. I find using a good quality window cleaner helps.

As suggested switch off AC just before completing your journey & I would double check the rear washer feed under the plastic trim on pass side, you may have a slight leak + air drawn for the re-circ is on that side.

Hello Adrian

 

Thanks for your advise on the fogging windows, i found you were exactly right in what you said, damp leaves , blockage down by passenger strutt, i used a hose pipe with the fitting taken off to clear the leaves and then fed the the hose pipe deep down in the corners to clear the blockage down by the stutts, hey presto the mucky water eventually ran out under the wheel arch

blockage cleared the drivers side didnt appear to be blocked but the passenger side was

FOGGING HAS CLEARED

 

Thanks everyone for your suggestions on this one, using the hose pipe really saved a lot of time, i regulated the water supply by bending the pipe to turn the supply on and off ! nothing like a good flushing out ! top tip

 

Regards

Garry

I have got the same condensation problem,could somebody tell me where to stick the hose pipe(no sarcasm please cause it wouldn't fit, I hope)

[seatkid]

:lol:

In the far corner to the right of the pollen filter (passenger side). There is another on the drivers side.

[delboyt]

remove 3 screws from the plastic wheelarch liner

near to the passengers door

pull the liner back & put your hand up toward the bulk head end

& feel for a rubber flap

putt it away & warte shold flow

if water don't flow out then get a

coat hanger (old metal type)&

prod it about into the hole

now get a watering can & pop some

water on the bulk head under the bonnett

& see it it flow from under the wheel arch

you don't neet to put the rubber flap back on if you don't wat to as

i left mine off & has never had a problem since

 

onto the fogging up

 

go to halfords or

similar & get a bottle of

rain x (black bottle)

for the inside of the screen

 

& rain x (yellow bottle) for the outside windows

 

use the inside one (black bottle) & you won't have any more fogging up

but make sure you do all of the screen

you can also use it on the side windows

to see if it work do a couple of them & leave others free & you will see

the diffrence

 

you can keep using your air con if you don't want to use

rain x but aircon is expensive to keep running all the time

& cold in the winter lol

 

let me know how you get on

 

happy driving

why is it too cold ? you just turn the heater to hot and run the AC :lol: quicker demisting as the AC removes the moisture from the air and clears the screen quicker, also running the AC keeps the system lubed and helps to maintain the seals

and it could just be possible that no warte flows out the hole because there may not be any? so before ripping half the car apart try pouring some water into the scuttle area near the drains and see if it drains away? if it doesn't then by all means tear it apart :lol:

[talke31]

Many thanks for help and advice will try tomorrow and let you how i get on

[Genepaul]

One thing that help for me was to actually change the pollen filter, mine was so bad that it was really reducing air flow into the cabin, you just need hands the size of a 10 year old and the dexterity of a gymnast to change the dam thing!!!

[delboyt]

no need to rip the car apart

as i said

3 screws under the wing & pop your hand up inside the

liner & pull the rubber flap away.

 

it is good to run the air con sometimes

but it don't help fuel economy & the gal

likes fuel as we all know so the use of

the rain x stuff really doe's work.

 

sorry if i got it wrong asto the aircon being cold

i only use it in the summer as my heater is fine

for winter without aircon running.

 

let's hope this helps out the newbies.

 

oh

vr6

i got the gal done at my local garage

i supplied the fan/aux belt

[talke31]

well i've flushed the drain channels,applied rain x to the windows at

[delboyt]

28" long

curved blades

 

frauds want

[Galaxy23]

seatkid,

In order to get to the drain hole next to the polen filter do you have to remove the scuttle panel and the wiper motor ,etc.

[Guest vr6galaxy]

Nah! just blast it with a hose :) works for me :lol: did mine today :) all running clear B) cant say the same for the pollen filter though! looked a bit blocked with road debri! looks like the mrs has been plucking birds under the bonnet there was that many feathers in there :lol:
