Originally posted by Ocy_RS_TDi_Kombi View PostI've found with my car regardless of what the recirculate button is set to, when I turn the A/C on, the car automatically goes into recirculate and fresh mode on its own (you can hear it suck the air from under the passenger side of the dash and then change to fresh when the fan speed is high). I've thought of getting the dealer to look into it but I keep forgetting when I have the car serviced.
I spent last weekend around the NSW Southern Highlands, and spent more time fiddling with the Climatronic controls than I wanted to. As with domestic reverse cycle A/C systems I don't find the "Automatic" mode of the Climatronic to be to my liking. I prefer to use A/C mode, and set the temp for heating or cooling, so if the outside temp changes due changing altitudes while driving, or I've pulled up and the car has been in the sun for a bit I need to make adjustments then readjust once conditions have again changed. The seat heaters are great, but the Auto mode just doesn't do it for me. If I'm generally comfortable, but say my legs are cold, as soon as I hit the button to direct warm air to my legs the Auto mode is cancelled anyhow. I find it fiddlier, but for my comfort more effective just to use the A/C mode. Just wondering if anyone prefers the Auto mode, and if so why.

The biggest issue at this time of year is that all cars are damp inside and they tend to be locked up tight when parked overnight and driven with the windows closed which means the moisture condensates on the inner surfaces of the windows as we all know.
The absolute best thing people can do is open the windows at any opportunity and dry the inside of the vehicle out. Days like we have had over the last week in Melbourne are perfect. If your car is parked in the sun somewhere during the day open all the windows an inch (2 cm for young people) or so before you lock it up. Getting the moisture out of the car first goes a long way to stopping the thing condensating overnight.

Problem is we are cold/damp as we are high up 700m and more likely to get rain given our location the the ranges.
Worst car we had up till now was the old Honda CRV always wet and damp inside but a quick dry in the sun worked a treat. My old Merc 190 was also a bad offender with dam inner windscreen. Hopefully a bit of sun now and again will keep everything dry.
I also added some damp rid to the stored cars to assist in the drying as ordered a couple of rechargeable ones for the Skoda.
They drying seems to work a treat, was -3 this morning and the car frozen shut, but undercover and no problem with fogging.2012 Lava Blue MY12 Skoda Octavia 90TSI manual

So, the A/C is an excellent way to demist the windscreen, and it has the added benefit of keeping the AC working in the colder months.
The MAX option for demisting does exactly this. It uses high fan speed and refrigerated air well before the engine temperature has had a chance to get up to have any effect and turns on the A/C.Last edited by wai; 24-06-2013, 12:49 PM.

I didn't think it necessary to explain why A/C air is dry. I thought most here might know that whether outside a house or a car when the A/C is on the external drain tube will be emitting condensate that was present as moisture in the air inside the house or car.

Note that MAX only kicks in the Climatronic air above 0C. dagget mentions -3C, which doesn't surprise being on top of the GDR. It's not only cold up there, but the humidity doesn't drop below 90-95% through June and July.

Has anybody ever wondered why on a sunny day in Winter many used car yards have all the cars open with the boots and bonnets up and the windows down? Well now you know....

By the way, I recall a friend of mine had a Mitsubishi Magna, and it had a reverse cycle A/C so that you had warm air to warm you and demist immediately the engine started.

Originally posted by K1W1 View PostAll European cars since the 1980s have had the optimum settings for demisting clearly marked on the heater controls. These days it's often a push button in the old days it was a correct setting for the levers and knobs. To demist a European car you don't even have to open the owners manual you simply have to open your eyes when you are sitting in either of the front seats.
We're a bit slow in Oz. It's not that long ago that we caught on to double glazing our houses. It was never done here because of the attitude that this isn't Europe, so we didn't need it.
The same logic applies to trucks. In Europe trucks have night heaters. An external burner uses a tiny amont of fuel drawn from the main fuel tank to supply warm air to the cab for sleep/rest comfort. They can also be set on a timer, so if left unattended in a yard the heater will come on an hour or so before the driver turns up, so ridding the hassle of deicing windows, and or getting a foot or more of snow off the cabin roof. Seemingly Australian truckies mostly prefer to freeze their rear ends off.
The same with cars. European cars have night heaters as an option. Skoda call it Auxiliary Heating. It's in the book. While working OS. I've had a BMW, and a Range Rover with night heaters, and they're nothing short of brilliant.
I've no doubt that if I lived in Canberra, or anywhere on top of any of the ranges or highlands where the temps go subzero and are mostly below average, and where the winter humidity is mostly higher than average that I'd have ordered one as an option ex-factory when buying my Octy.

No worries. Written words don't always get taken in the context they are written. Especially the way I can butcher English.
I've heard of a 4-way reversing valve that can be used to convert standard auto a/c to reverse cycle, but didn't know about the Magna.
I've seen it mentioned for caravans, but for cars I'd think demisting at cold start is the only time it would be useful. Once the engine warms up it becomes redundant.

Apart from making sure your glass is kept clean which always helps, could also be your interior filter. I always wondered why my air con was sluggish, demisting, etc.. pulled the interiot filter out and it was so black, like charcoal. put a new one in and wholah... good as gold. air flow much better, stronger, air con heaps colder, air through vents 200% better...HAve you checked it?
