    Default Air Conditioning question

    Morning all,

    Just a quick question as this one keeps bothering me. On all my previous cars with A/C including my 58 plate Golf, when you put the A/C on the auxiliary fan starts up in the engine bay and runs until you turn the A/C off.

    On my 2.2DTI, when you switch the A/C on the aux fan(s) do nothing. Late yesterday I took it out for a run and it was 24 degrees so the A/C was on a lot. The car got right up to 90 degrees on the water temp but still neither radiator or the aux fan cut in.

    I have no fault codes, no warning lights and the fan blades seem to turn just fine. All connectors are plugged in too.

    Any ideas?

    Thanks – VF.

    Was the air con blowing cold air? Did the car overheat? If the answer is yes and no there's nothing to worry about.

    The answer is Yes and NO. So I'm happy then and that's all that counts

    Thanks

    On Vauxhall's it will come on as and when required. The fan won't run all the time.

    Its due to the pressure within the A/C system. If it rises to a high enough level it will start the fans, which will cut off below a set pressure.
    Now I need a turbo to keep up!
