    Hi All,

    On my 99 s3 I have had a weird fault with my air con!

    When i put it on the air con on it does not always work. I can drive home from work and nothing (cold) i open bonnet no fans and compressor does not kick in and out when i press the button on the unit.

    I can leave the car a while go out start it turn on air can hey presto the fans come on and the compressor kicks in all fine!?? And perfect cold air!??

    I had it cleaned and re gassed last year and it didn't help as it did not come on after i had had it gassed
    drove a short while and it came on.

    Is there anything worth checking and cleaning etc wires, fuses relays fan swithches....... Head doer.com

    Sounds similar to mine.... i'm going to investiate this week ... it's as though the clutch dosn't always engage... could just be an intermitant electrical fault .... i'll keep ya posted if i come across anything
