After a bit of help and advice guys, just recently with all this cold and wet weather were having ive noticed my car seems to get full of condensation in no time at all, theres no damp or water getting in anywhere in the car. I Did change my headliner before the weather started getting cold. I was sat in really bad traffic jam on the motorway a few weeks ago the weather was lashing it down and my car was get misting over in no time at all, id blast it with the heater and it would clear the majority of it but once i shut my window again and turned my heated off it would slowly come back, there was me and a friend in the car. Even when i leave the car over night and come to it in a morning the is condensation on the inside of the windscreen, i expect some but compared to my prents and sisters cars whos will have been sat on my drive all night having not been used where as mine will have been sat there from normally 11pmish there is a lot lot more, i wouldnt expect this as surly the car will be warm giving less cause for condensation. Just wondering if it could possibly be the pollen filter maybe? Ive not experieced anything else, allthough my heater doesnt even seem to be "cold" when its set on "Low" its never freezing. I very very rarely experience a bad smell in the car....normally i just put this down to ermmm my bad ass lol! and normally cant smell anything due to magic trees lol!
