thank you all for all your help. the car doesnt have air con. i dont even think it has a pollen filter? it is a vw golf mk2 1987. i have had 10 of these and every one has done it. on each one, i resealed (properly) all the door membrane/sheets/skins, bypassed the heater matrix (as this was a recall/fault on all mk2 golfs) and still it steams up, and freezes up. i think il never get to the root of the problem, which is why i have asked the best way to clear the windows? im presuming opening all windows,doors if poss,and putting the blower on windscreen on cold when i get to the car in a morning will help? or should it be on hot? and/or is there anything else that will help? everywhere in the car,even under the carpets in bone dry)
