Thanks for advice; didn't go to Halfords, I though I would check the last service schedule done last September, =A3500 with 2 new tires and MOT. It states on the check list that air con/pollen filters were changed, on the invoice it states two element filters at =A310 each. I will check to see if these have been replaced at the weekend; they seem to be under the glovebox according to the manual.
Nothing wet in the car, though the boot hasn't been checked, full of the kids bags, there might be something in there.
I only do short runs, two 4 mile trips a day, so perhaps the air isn't been dried out; however the screen freezing up is a new thing, didn't happen last year.
I live in harrow, outer London suburb, my astra only started doing this after it started leaking water into the inside of the car, so nothing unusually cold about my area..
Car is parked on a level drive
If I don't sort it, I'm going to be extremely fed up; the car was a hand me down from my mother, still have to pay for it, though she doesn't want anything for it. I was quite happy with buying old bangers after I got rid of the Astra; bought a LX 1.8 serria for =A3200 notes with six's month MOT, replaced this with a Ford Granada for =A3200 with 12 months MOT and then sold the Serria for =A3180. took the Granada to France and back again, used it for 8 months before the head gasket went, then desperate for a car as I need it for the school run in the morning and was emotionally blackmailed into taking the Honda. Now shelling more on a service than I paid for my previous two cars and the dam thing is doing exactly what the Astra did before I got rid of it :-(
May try the cat litter trick, sounds a good idea, may also try it in the house to remove the condesation on the bedroom windows
Thanks Brian
