RE: [alfa] Milano heater fan, etc

Mark -

Actually, the heater fan motors are available.

Last time I checked (a few months ago) Difatta had them.

However they do not include the squirrel cage, so that has to be removed
from the old motor and reused. I have not quite figured out how one would
actually remove the squirrel cage without damaging it.

In my case I had to separate the motor from the plastic shroud that holds in
it place as there was not enough room to extract them as a unit (would have
been much easier to do it this way if possible though.)

It's a bear but it can be done.  It should slide out as a unit (motor,
squirrel cage, and black plastic shroud) from the driver's side.   The
speed control is screwed into the ducting by two self taping screws.

Good luck, the fans are NLA.  You can still get the ones they use in
Europe, but they are of a much different design than the US ones.  If
you are patient and resourceful you might be able to rebush them...
it's tough because it's a spherical brass bushing at the end that is
probably worn out.

The speed control is simply two or three coils of nicrome wire connected
in series.   If they over heat the car either burns to a crisp, or the
wires connecting the loops together acts like a fuse.  They are pretty
easy to fix with a soldering iron.   It would be interesting idea to
switch to ceramic resistors or a more modern speed control (mosfets?) as
the stock device gets scary hot.   Becareful if you bench test the speed
control... without being in the airflow of that duct, it will get red hot.

There is some info on the Milano heater on the old Milano Resource...  I
haven't moved it to the Wiki yet:
