    I noticed that when parked, the airco fan sometimes switches on
    for long periods. Outside temperature was over 95°F.
    I've been amazed to feel that it blows quite fresh air, even 20
    minutes after the engine -and the compressor I guess- was shut off.
    Is this normal?

  2. It is part of a system they have to keep smells from forming in the AC
    system due to moisture and fungus forming. Letting the fan blow dries
    out the AC system.

    If you're talking about the fan inside the car, then that's normal.
    It's to dry the condensation caused by using the A/C, which inhibits
    mould formation (smell) and corrosion (expensive part replacement).

  4. I believe that this facility was removed on later models with internal
    movement sensors, because it set off the alarm. It is now a good idea to
    turn off the air con a few minutes before stopping to allow the evaporator
    to dry off, which achieves the same object.

  5. It was still that way on my 2001 V70, the A/C fan comes on after we
    leave the car. It gives the normal condensate time to run down the walls
    into the drain. Then it kicks on the fan to dry it out.

    And it sends a signal to the alarm as to what it's doing, so the alarm
    doesn't come on.
