not long had this car, when its cold outside and you attempt to demist windscreen the whole of the car condensates and you can,t see out of the windows etc. Only clears with air con on. Gets expensive on long journies. Any clues please. Thanks in anticipation.

Are you sure the heater is set to "fresh air" and not "recirculate?"
Is there any sign of a water leak, e.g. damp carpets including in boot?
If you have previously been running the air con, it will have acquired a bit of condensation inside - you have to run it for a short time with air con off for this to evaporate. This becomes a vicious circle, when I had the prob I used to run the heater with the windows open for a couple of minutes while the humidity dropped.

Check for a blocked drain from the bottom of the heater/air con unit in car, if this is blocked, condensation from cold air con collects then evaporates into heater air and mists up screen. it's a common problem with air con cars.
The cooled air from the air con unit is dehumidified by the cooling process and this is where the excess water comes from and also explains why using air con demists quicker than hot air, because the air is drier.

What age is the Zafira? my 2003 astra used to steam up badly, but a simple change of pollen filter remidied it.
i'd try that first off.
