    I've a '97 850 wagon, and it has started
    to make a load humming sound whenever
    I turn on the air fan (for heating). The sound disappears when I turned off
    the fan.

    Does anybody know the cause?

    Thanx in advance.

    The bearing in the motor for the fan is bad. You can try fixing it with
    lube, but a new one is probably the way to go.

    This also happens to me, but whenever I have it on the higher settings, 3 or
    4.
    Is it an easy/cheap fix?

    It depends on the car and whether you do the work yourself. On the 850
    an experienced guy can do the heater motor in less than an hour.
