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.
