    ac fault finding

    ive just had my ac re gased as was not working and no sign of leaks, but when picked car up he says there was 690g of gas still in there and only meant to hold 760g so was more than enough to kick in ?????

    now i no thers no leaks im stuck why it don t work

    if i press the ac button the engine note definetly changes so i presume the clutch on the compressor is good ( thank god)

    is there any test i can do myself on ac unit etc or is it a case of throwing money and ope something sticks lol

    thinking ac pressure switch but can i check 1st????

    If the pressure switch was shot, the compressor wouldnt kick in.

    Have you actually looked at the compressor to see if the centre spins when you press the switch? (ie the clutch works..) as some systems increase the revs at idle so as to compensate for the extra load.

    When the econ light is lit it means the air con is off ie for economy running. So when it's not lit the a/c should actually be on !
