[s-cars] S6 climate control 'squeek'

[Franco Barber]

I've been paying more attention the last couple days when
this has happened, and in my case, the noise does not change pitch
or loudness as I vary the fan speed.

I get more or less the same noise, same pitch, same loudness, from
the 1st segment of the fan speed display right up to the top.
The noise only seems to go away OCCASIONALLY under some of the HIGH
fan speed settings.  I don't know if it goes away because the increased
airflow through the system results in increased airflow through this
little auxiliary fan, or if the resulting noise of the air flow drowns
out the little motor noise.

I have also noticed that the noise usually starts after hitting an
expansion joint or a pot hole or some other jarring event.  If the
roads are smooth (ha) I'm less likely to start hearing this noise.
