Dreaded damp windows- Suddenly.

over the last couple of days the moisture inside the car has been absurd, washed the car Sunday and just wondering if when cleaning under the bonnet if water enters the plastic grille at the base of the screen this could be the cause? It was boggin under the bonnet so washed it all down and now have seen a strange wee symbol on the plastic cover that might suggest NO WATER, have I done this with my enthusiasm? I assume if there is water where it shouldn’t be it will dry out -sometime- if the heater is on and the windows open whenever the car is used. Is it worth checking the pollen filter isn’t wet? Ta.

I find the pressure washer gets water in places the hose pipe could never reach. Now when im on the drying stage I open all the doors to let the water drip out the seals and to let air circulate round.

Same here after no wash but regular use. The car was full of passengers too. So that, plus the increased relative humidity and cold morning air and you’ve got a heavy layer of moisture to dry before you can move off.

Its just the weather. My windscreen was soaking inside this morning but its so damp and cold outside all the time that nothing dries very fast.

Don't worry, it happens every winter.

I will usually change my pollen filter around April and October each year as the weather changes.

Do other VAG cars suffer from the same problem or is it a Seat problem mainly?
Not just a Seat problem; crops up pretty much every year on many of the VW forums. A quick internet search, and it happens to Audis and Skodas too.

It’s not just a VAG issue though - some other manufacturers’ vehicles seem to be similarly affected.

I work for volvo... a Swedish brand of car, famous for cold weather. Also well known for not being able to seal a windscreen properly.... letting water in....

There is a huge difference between a large water ingress and a bit of condensation inside the car... you also have to remember, if you leave a load of things inside your car, some of witch may be damp, it's going to condensate..

If your footwell carpets are dry and the car is clean and it drys out within say 3-5 minutes this time of year, your car is fine !

I think part of the problem is the car is actually really well sealed so when there’s moisture inside and it hasn’t dried out before you finish your journey, then the temperature drops, it ends up as condensation on the window.

I have a 30-45min commute each way so my car gets nice and warm so usually no problems but i have noticed condensation inside my car in the past 2 weeks when I’ve been off work and only doing short journeys as it hasn’t been getting heated up much.

I have never had any problem with any of my cars ever.

I always leave the Climate control or aircon on so car remains dry all the time and when I return.
I get into so many other peoples cars and see a problem windows dripping and notice air-con off, climate on eco, no air-con, recirculate on as they do not like outside fumes etc etc.

Such a shame they have not sussed the problem out.
YES there could be a water ingress issue or blocked channels etc. Worst case was shocking sopping wet all the time despite aircon [though they had switched it off as it said it made a hissing noise on idle] but when I mentioned cleaning the screen with windscreen washers found the pipe broken under the side panel ans flooding the car.

Since a dirty pollen filter makes this worse, would in winter removing it help the airflow through the heater, the fan seems to reach peak flow before max speed, I would go and try this but it’ p*ssing down outside at the moment.

I know that cars existed in the past with no cabin filter, but I'd be a bit worried that crap could get into the heater/chiller box and build up in a way that meant opening things up to restore things. Older systems were probably larger more open and more space wasting than modern cabin heater/chiller boxes. Maybe I'm over complicating things, running without a pollen filter for a few days could prove or disprove the point about it being prt of the problem.

+1 for leaving A/C or Climate Control on 24/7.

I’ve also never had an issue with damp windows inside the car, other than many years ago when I owned a Vauxhall Astra without air con in the 1990’s. The car had a blocked / waterlogged pollen filter, and the combination of a wet pollen filter and using the heater on the screen to try and clear the moisture was making things significantly worse! A new pollen filter fitted and problem solved.

My civic type R was a non A/C model that came without A/C and had no pollen filter fitted but I was able to fit one since the heater box etc was the same for both models hence my question, will pull the filter out when the weather dries out and give it a go and report again.

12 years ago I had a mk4 Golf GTi..... the plastic scuttle panel above the polen filter was known to crack on these. this let any rain water, car wash water etc, drain straight into the polen filter housing and into the cabin.... The carpets were like a soggy sponge....

I wouldn't be spraying a hose / power washer into the engine bay on any car.... IMO of course.
