02 1.4 Heating steaming up windows - clewsy01
Hi I have had my car now nearly six months and I have it running perfectly apart from one thing. When I try the heating system my windows steam up. The only way I can clear it is by using the Air Con and that makes my car freezing.

Obviously its winter and I dont want to freeze everytime I drive. I have changed the pollen filter when i got the car which looked like it had'nt been changed ever since the car was built. Just a bit lost at where to look.

Are you saying even with the aircon on, set to hot, the windows are steaming up?

Maybe air recirculation switch stuck on.

yeah. If i have the aircon on and the heater set to warm it is still cold air. The heater on its own does get warm but fills the car with miosture.

Have you checked the cooling system to see if it requires topping up?
Also, have you checked to see if the carpets are damp?
Don't do a taste test as antifreeze is poisonous. I mention this as some people press their finger into the carpet then place in their mouth to see if the liquid is sweet.

Suspect that your heater matrix is leaking slightly.
Probably not enough that you have had to top up the cooling system.
Just a slight leak that vapories immediately on the hot matrix then condenses on the cold windscreen.
Try some radseal in the cooling system.
If it effects a cure you can just run with it or arange to get the matrix changed later at your convenience.
