Am i right in thinking that the AC/CC only works when the outside temp is 4c or over as on the way home last night had it on but would not clear the windons as well. And if so is there any way to over ride the system.
Would be good to have it working even if it - c outside?.
Thanks
Steve.

Mine seems to work, regardless of the outside temp. run it constantly, winter and summer.
-
it would be less efficient when it is colder as the water temp may not be as hot, but i have not heard of it not working when it is that cold.
override the auto by choosing the temp and then selecting the fan speed and direction of airflow (feel, face, windscreen) this should be the manual settings

Air-con doesn't function below 5 deg' i.e cooling compressor switches off below this temperature

Is there anyway around this not a big prob but with it been -c most days and nights it would help.
what do you guys do.
-
The climate should work as a heater. The only difference is that the air con compressor doesn't run. Its only function when heating is to reduce humidity of the incoming air and it can't do that if the evaporator ices up, which is what would happen if it did run.
In any case, approaching freezing temperatures humidity should drop off rapidly with even a little a bit of heating.

It would be worth doing a climate control system reset and see if that cures the problem.
You will notice that I have cunningly omitted to tell you how to do this and that's because I can't remember what buttons to press. I'm sure that someone will be along soon with the right info. :y

Thanks all i will give the re set a try :y.
-
i heard about it not doing certain things below certain temps, but when i cant feel my fingers and the heaters work, i shant ask for more!
-
Given that you aircon cant chill much below 6 deg....there is no point in running it if the outside airtemp is below this..........hence it turns it off.

It took miles & miles before the screen on my car started to dry out. It doesn't get used much, & when I got in today the inside of the screen was soaking wet! :( I tried it ECO off & on, on AUTO, recirc but it didn't make much difference until I turned the ECO off & opened the window - like in the old days! :y Astra shed that's used every day & has non working A/C is fine. :-?

Might also be worth checking your recirculation isn't stuck on, as that will prevent any fresh air entering.

Never thought about that. I had the same problem last week when it was piddling it down. I'll check later - where's the recirc flap? :-/
-
And also check that your pollen filter is good and not dirty/damp due to blocked scuttle drain hole.
Cheers Pete
-
I think it's part of the blower assembly behind the glove compartment. I believe there's a vacuum valve on the centre console side which operates the flap through a length of vacuum hose. You should hear it moving if you turn recirc on/off, if not from within the car, certainly through the pollen filter housing.
Normal vacuum system checks are probably a good idea before dismantling, i.e. is there a good vacuum on the vacuum pipe that goes through the bulkhead with the heater matrix hoses? (not the one that feeds the HBV, but the other one.

I checked that last week - all clear.
I've just had a quick play with the recirc and does do something when pressed, there's a slight change of air flow in the foot wells. Perhaps I should just use it a bit more. It's amazing how fast & heavy it feels when your daily driver is a low-blow turbo diesel Astra! ;D ;D

I get this problem on my BMW, as it can go several weeks without being used and in this weather sometimes the windscreen has huge droplets of condensation on it. I hate wiping it as it leaves smears that show every time it steams up again, so I just have to wait an age for the heater to slowly evaporate a lot of water. PITA, but there's no solution I'm aware of, AC or not.

Mine even had a few frozen droplets on it this morning! :o I don't really like to wipe the screen either when it's as wet as it was this morning but I had a daughter to collect & didn't have time to let it dry by itself.
The real p***er was later as I was joining the M6, the washer nozzles must be full of sh1te cos as I tried to washer the screen I got no water but the wipers went thro' their cycle & smeared the screen to the extent that I could see next to f*** all. Just what I wanted! NOT! :o
-
If you have excessive condensation, it may be worth checking that your scuttle drain isn't blocked by dirt, leaves, small children etc.

A quick Google brings up a method for re-setting the servos.
Hold Auto and Off together for 5 secs. With ignition on...

That's the ones, I couldn't remeber which, but other combinations do nothing so I normally go by trial and error. :y
