    A/C question

    My aircon seems to switch itself off when outside temp gets below a certain level and you can turn it back on until it reaches about 4deg. Is this normal? Whats the idea behind it? Just seems that at a time when you need to demist the car most youre not able to.

    Re: A/C question

    No this is normal. It is to preserve the life of one of the A/C components (can't remember which one, dryer or compressor I think). The temp varies as to when it shuts down as the temp shown on the DIS is an average of a number of sensors dotted round the car, whereas he shutdown just uses one of the sensors.

    I had this so actually read the manual, and as Andy says, its quite normal for it to shut down at 4 degrees ish

    Cheers fellas.
    Fallmonk; its more the rear side windows that bother me as like you say you can blast the front screen and whacke the demister on the rear one. Oh well, just drop the windows a crack then, lol.

    Re: A/C question

    mmmm.... mine was playin silly beggers yesterday. i takes a while to demist the screen, and the fan dosent sound like its blasting at top whack....
    as i thought i had a gremlin, i checked it over.
    the outside temp was below zero and the cold air con didnt seem like normal ? does its shut the aircon unit off when below certain temps ?it just seemed like fresh air blowers, cold from outside air, but not aircon cold ?

    i dont have a book, for the car so cant read up.
    please tell me this is normal. please. please .please....

    Re: A/C question

    OK folks - I understand the 3 and 4 degree cutoff zone. But, what is the primary sensor for this temp??

    Re: A/C question

    there ar about 13 sensors all over the car and the A/C uses the one behind the bumper (I think), which is why the cut out varies from the temp on the DIS which is an average of multiple sensors.
