Steamy windscreen
Hi
Just got a Xantia but am having problems with the windscreen steaming up.
If the A/C is on the screen clears instantly but if I switch it off the screen mists up quickly.The control is set to re circulate the air.I have tried all possible combinations of setting but the screen will only claer with the A/C on.
I have just done a quick search and found a post sugesting the heating matrix may be leaking.
How do I check to see if this is the problem?
cheers

Try switching the re-circulate off, A/C off and leave the fan blowing full for a few minutes. On mine if the A/C has been on for a while then switched off the screen steams up too. If you do the above it demists on mine.
If the air is on re-circulate it will steam up after a while as no fresh air is getting in the car and will become more and more humid due to people in the car breathing the air.
Hope this helps

You ain't got a blocked pollen filter? or may be a wet one (pollen filter that is)? VX Tigra once with a small split in the windscreen valance over the pollen fiter. This let in just enough water to soak the filter. Blower on, would send moist, damp air in to the car. The air con would dry it as it came through.

Ok, back to basics ..... I drive a brand new car and it does exactly the same. The explanation is simple if you think about it. People use their aircon whenever they can with this humid weather we have the last few weeks. If the A/C is on it cools the car but also the COOLS the windscreens! When switching it off, the windscreen is close to sub zero and will condens due to the humidity. Common sense to me though, but members here might proof me wrong! Don't think the heater matrix is the issue here.
This is the UK remember .... [}:)]
Cheerio!

On the plus side the car dosen't smell of anti-freeze and the car is totally dry inside.
When the fan is switch on I can feel air being blown at the windscreenso the fan is working ok.
In my original post I said the control was set to re circulate when in fact it is set to fresh air.
If the A/C is off the whole car slowly steams up over time as if the air is being re circulated.When the control to change from fresh air to re circulated is move I can heard things moving and the tone of the fan changes so i am pretty certain this is working OK.
I have not checked the pollen filter yet but wil do as soon as i get chance.
If I were to leave the A/C on all the time would this cause me any problem

My xantia 1.9td steamed up really badly with a/c off but that was the radiator on its way out so moist air was sucked in from under the bonnet, if you're not losing any water then it's just the air condensing on your cold window. I leave the a/c on all the time and I'm getting average 45mpg with mostly A road driving.
