I recently purchased a new 207 and although I love it, am facing a few issues with the demister. My windows (both the side and front) keep on misting up in cold weather and despite having the demister on full, I'm finding it difficult to see out. Has anyone else experienced this?

The obvious question is do you normally run with air conditioning on? If so this will cause the misting and you need to use the air con to clear it?

Sorry, so you're saying that running air conditioning will solve the problem?
Thanks

Recirc button needs to be on fresh air and if fitted aircon should be on.
Just seen your post above mine - yes aircon dries out the air and prevents misting.

In my experience misting can be a problem in cold/humid weather after the aircon is switched off. The misting is caused by residual moisture in the heater/aircon system (i.e. not all the moisture drains to outside) coming back into the car. Try running the car without the aircon in use for a few days to dry out the system and see if the misting decreases. During the drying out period you may need to concentrate on getting the maximum demisting effect from the heater ~ maximum temperature, all the air to the screen and maximum fan speed. It's all down to trial and error.

I have my air con switched on all the time regardless of weather conditions and never suffer any misting problems.

What happens when it's very cold and the a/c won't work - most systems don't work below about 4C?
Daughter's Colt is has been bad for this on a couple of frosty morning so far this year after having been driven the previous evening with the a/c on (it comes on on its own when the air is pointed towards the scren). Short of wiping the inside of the screen there's nothing that can be done until the car warms up a bit.

I?ve not noticed any problem with the air con when it?s very cold, but next time I venture out in sub 4C I?ll see if I can detect any difference and let you know.

Air is dryer as it gets colder so it's not really a problem in continuously cold weather, but it can catch you out if it's suddenly cold overnight, having been raining the previous day (so you'd have left the system 'wet' if you run it all the time).
The a/c becomes less effective at low temps anway, but it has to turn itself off at very low temps otherwise it would freeze up.

"despite having the demister on full"
Air-con usually works much better (by drying the air) but if it's a persistent problem, I'd check for damp in the vehicle. Carpets can hold a lot of water before it becomes obvious and it might be creeping in past the door seals, or elsewhere. Press some paper towels onto the floor in the footwells...

If it was a not so new car I would suspect the pollen filter but the above comments re air con being on all the time and providing moisture extraction from the circulating air are spot on.

"I would suspect the pollen filter"
Do all cars have those now? I have absolutely no idea where ours are (well, I can guess, but I don't know how to get at them).

Has most details of where a pollen filter is located.

Thanks, DD. I knew someone here would know.
