For the discussion of alfa romeo cars

156 Aircon Compressor Mode

On the single zone A/C in a 156, I seem to remember that you can
change what happens when you press the button that
activates/deactivates the compressor. IIRC, in one mode, the
‘compressor switch’ remembers it’s setting when the ignition is turned
off and in the other, it turns the compressor on every time the
ignition is turned on regardless of the previous setting. I think
there are other differences too.

IIRC, someone here provided details of how to switch from one mode to
the other. As my searching revealed nothing, anyone remember/know how
to do it?

    And if anyone can translate the manual section on the AC for me, that would
    be good too.

    I can only get heat by turning the temp *right* up, waiting for it to kick
    in, then turning it down.

    Oh, and the compressor turns itself on randomly, while driving.  Which is
    nice

    This is normal. The mode I’m in is the other one where the compressor
    follows the green lighted switch exactly regardless of all else and
    the green lighted switch remembers its setting over a power off. I’m
    getting to like this mode in the colder days (keeps the humidity down
    in the car) when it’s cold outside but I want to switch back to your
    fully auto mode in the warmer months.

    The reason I’m in the wrong mode is my Garage left it this way after a
    recent A/C repair (rubber & metal hose failure). I haven’t asked them
    about it yet.

    You serious?  If I decide that my car is dry and cold enough and I turn the
    compressor off, the car can decide to to turn it back on again?  What am I
    driving? KITT?

    Maybe we should just swap cars ;)

    Is it likely to be in the handbook?  If so, I’ll dig it out for you / us.

    Sorry. That’s not supposed to happen. I thought you meant the
    compressor was going on and off with the green light always on.

    Ha Ha..I haven’t looked there but I doubt it is. ISTBC. I have a
    feeling that the mode I’m in and, perhaps, you want to be in is a test
    mode to force the compressor to operate on the button as well as stop
    it trying to start on every ignition turn on.

    Ah, no. I know *that’s* supposed to happen.  My green light comes on all by
    itself

    Hmm.   I’m getting this tickling in the back of my head about somethign I
    tried to read.  THe whole AC section is pretty impenetrable IMO, but if I
    get a chance, I’ll dig it out tonight

    That’s because our cars have /climate control/, not your bog standard
    aircon.

    The climate control will automatically control the temperature in the
    car, using the aircon pump when it sees fit.

    This is the major difference between aircon and climate.

    Personally, it’s a non-issue to me.

    It won’t, ‘cos that’s just switching the climate system ‘on’. If you
    want to run without the compressor you have to put it in ‘economy’ mode
    by turning off the green light – then the system will do it’s best to
    maintain temperature without the help of the compressor.

    The Panzer has ‘auto’ and ‘economy’ settings, which do exactly the same
    thing. Even I’m not tight enough to use the ‘economy’ setting, ffs!

    This is the odd part. I say NO. Once the user pushes the button
    it changes mode. Green light OFF and control set by user with
    dials above… UNTIL  the ignition is turned off. System will re-start
    with the default Green ON.
    So I think that you have a niggle problem IYMV from that. Which is
    certainly how it reads to me.

    Doesn’t a 2001 car have the updated dash, though, with digital climate
    control?

    Could be wrong, ‘cos I can’t remember the changeover year.

    Not in mine. I have seen the changed version in loan cars, but
    not certain when the actual change took place.
    May be late 01 but more inclined to guess 02.
    I regarded it as the slippery slope. Next step, changing the nose,
    and end up with a car that may well be lovely but not DeSilva :-)

    Indeed it is!! Thanks Ivan – I hadn’t spotted that info before! Ooops.
    I’ve tried it in the garage and it doesn’t seem to work as I’d
    expected. I’ll give it a proper try when I get the chance – Wife and
    Kid are moaning at me to do something else now – they just don’t
    understand….
