As you've probably notced it's very cold today, -2 here as indicated on the car's external thermometer. I sprayed half a can of de-icer on all the windows but still couldn't see through the front until I noticed there was a very thin layer of ice on the inside of the car. I've never seen this before and had to wait about 15 minutes in the cold with the heaters blasting for it to start melting. Of course now I've got a dashboard which resembles a paddling pool.

How could this have happened? I haven't used the car since Saturday afternoon and there wasn't any water inside it the last time I checked. Could it be the pin-hole gap between the side window and frame letting moisture in?

If I had to guess I would say it’s because your car had warm moist air trapped inside it and when the temperature fell rapidly it condensed on the windscreen and froze.

Either that or your teenage daughter has a boyfriend she isn’t telling you about.

Or could it just be condensation that has just frozen up?

How can I stop this happening again? Waiting quarter of an hour in the freezing cold each winter morning for this crap to melt simply isn't an option.

I would check for any water on the carpets etc. Used to happen in my BMW conv. Found out a leak was making the rear carpet very wet, and that caused lots of condensation, which froze on the inside in winter.

I used to get this. Try running the a/c on a warm setting for a few mins before you get out of the car. Should dry most of the air/condensation.

Drying the car out first, at least if it happens again, you know you have a leak. In a garage, windows open, independent heater churning away (not the obvious car heater or you'll choke from fumes).

Little disclaimer thrown in there for good measure

My first thought was that you must have a Lotus Elise - used to happen a lot. bought one of those dehumidifier things that uses the crystals to keep the car dry (ok, drier) inside.
Sounds like more effort than just running the aircon hot for 5 minutes before you go anywhere, but really depends how often you are late in the morning and don't have time for that (and if you even have air con or not)!
you can get em from halfords (in the caravan section I think) and DIY places.

All cars should have heated windscreens! Does anyone other than Ford and Renault do them?

Did you leave anything damp in the car? I went swimming yesterday and left my kit in there all day and the car was really struggling with the condensation. If it hasn't happened before it sounds like the car needs a good airing. Have you got A/C? If you have I would leave it on whenever you are in the car for now to help dehumidify the interior.

Will stick the A/C on full for the ride home then and cross my fingers for the morning.

Same problem. Alfasud sprint, leaky boot.

Anyone know how the water usually leaks in that area on these cars?

My solution of having a rust hole in the floor to let the water out seems insufficient

Open your windows 5 minutes before you end your journey next time you go out, Your breath contains moisture and thats what is freezing on your screen so opening your windows in good time before you leave it should prevent it happening next time.

It works for me.

I use a couple of large Silica gel desiccant bags to prevent this and pop them on a radiator once a week to dry them out.

Also, a dirty / smeary windscreen that never sees a chamois tends to condensate alot more than a clean one. Do you smoke in the car?

Woke up to an icy windscreen (both sides) as well; I just sat there with the engine idling for 5 mins waiting for it to heat up and melt.

I have this problem on my mobile windsurf shed (A Volvo estate) I keep all my windsurf kit in permanently. So after a trip to the beach it's usually saturated with water not to mention that lovely wetsuit smell. Anyway I just drive home with the windows open & the heated seats on. Sure enough by the time I'm home it's mostly dried out. I leave all the windows open a half inch too. Dry as a bone usually, shut them up & it's like the local swimming pool all misted up


Don't forget though de-icer works on the indside too

You can tell if your daughter/wife/nanny/hubby has been misbehaving in the car, tell tale footprints on the windows that show up in the morning condensation, as found out by my mates missus
