    Welcome mate

    Chances are the system just needs regassing. It is recomended this is done every other year to keep your system in top condition

    If after that the problem still goes on then it will need looking deeper.

    I know most the MK4's are controled by a module so I imagine the MK5 would be the same

    I have exactly the same problem with my Astra

    FYI, I had my A/C system regassed by Kwik Fit in June 2006 for the 1st time since new (check my other threads for info). The gas was down to about half. Since then, I have used the A/C every week throughout 2006 / 2007 and it has worked perfectly - until last week.

    Now the A/C light comes on when I push the button, I hear a relay click in the dash somewhere, but no drop in engine revs, no A/C compressor noise, no condenser fan operation, no cold air. All fuses checked and OK. So I left the engine ticking over to see if the radiator fan(s) had failed. They are both OK and start when the engine gets hot. Hmmmm. Sounds expensive........my gut feeling is compressor failure, or something equally as big / expensive.

    So, I organised for my Astra to go to Smiths of Ilkeston (my local Vauxhall main dealer) for a full A/C system check and diagnosis. Smiths tell me it needs a new compressor at a cost of approx £500 for a refurbished unit or about £800 for a new one .

    At this precise moment, my Astra is at Smiths and I've just called them and told them I'm not going to have the work done. I'll wind my windows down instead. So just £35 for the diagnostic test which is acceptable. I'll collect the car later today.

    Typical! 2 weeks ago I bought a new pollen filter off eBay and a can of Comma A/C cleaner because it was starting to stink when it was turned on. Not used either yet. The A/C broke before I had chance to use both. Grrrrrrrrr!

    Air Conditioning is an expensive luxury. It breaks if you use it. It breaks if you don't.

    Mine is exactly the same at present mate. Putting off getting it fixed until I have a bit of spare cash. I'd be very interested to know what the problem is with it.

    And I have exactly the same problem with my Astra!! I've been quoted 1000 euros for a new compressor (euros because I live in France!).
    I have written to GM France about this but they have refused to have anything to do with the problem as the car is out of warranty - OK it's nearly 4 years old but it's only done 36000kms (24000 miles).
    Looking at other forums this is a common problem with the new Astra. I'm absolutely disgusted as I've had various other electrical problems with the car from day 1 - stereo volume increasing on it's own, clock changing time on it's own, horn sounding ON IT'S OWN!!!! I had the steering wheel changed which solved the horm problem.
    More recently I had the stop lights on constantly (VERY SAFE!!) and no cruise control (presumably because the brake circuit was open!).

    The air con problem is really annoying - I don't have 1000 euros!!! I paid 18000 euros for this car less than four years ago and now it's not worth a light as well as being unreliable. It's our main family car and I'm just at my wits end to know what to do.

    Looking at other forums I also have a host of other problems just lurking around the corner.................

    Moan over!!! But if anyone has any ideas.................?

    Lucinda welcome to the forums

    I wouldn't say the compressor problem is that common on the astra's, yes it may come up a lot here but also think of how many other out there that don't have the problem......

    Chances are it's just the clutch that engages the compressor and is fitted to it thats at fault. You used to be able to replace the part on it's own on the older Astra's so I wonder if you can still do it on the later ones to help save some money

    Thanks for the welcome Autosparks

    Yes, I've read about the clutch too on the older Astras but it's certainly not an option that has been offered to me and, not being very knowledgeable about these things, not something I could deal with alone.
    I am going to take the car to an air con specialist (independant of GM) and see what they say.

    I'm really disappointed overall with my Astra, having had so many problems with it.

    I just wonder why GM have refused point blank to help - Mine was one of the early MK5's and it seems to be on these that the problems occur most. I suspect that by the time the Astra was launched in the UK GM had ironed out some of the defects.

    At the moment it is really difficult driving without the air con as we have temperatures in the 30's. Another thing that niggles is the my OH has a 10 year old Renault with air con - it's never been regassed, never touched and is still as good as new!!!
