My thought precisely, Marshall. I want to make it work exactly as designed
when Min is selected. Working as designed in other modes is a problem for
another day! I'm leaning toward a big magnet on the monovalve to keep it
closed.

123 experts,
SWMBO has made it abundantly clear that the ACC on the 85 300CD is
unacceptable. In hot weather the AC works fine but the monovalve control is
so indifferent that it initializes and hangs in full heat way too long
especially for someone who is constantly getting in and out of the car on
errands in hot temps. The problem *must* be fixed...or else...[shudders].
Direct measures are called for. The monovalve insert is fine. The foam tube
is fine. A valve to manually shut off the coolant line would work but it
seems that better ways are possible. We know that the monovalve stays open if
no current is applied. I would like to wire a relay to feed 12V DC current to
the monovalve to force it closed. So class, here is your homework assignment:
What is the most convenient source of fuzed, low amperage 12V switched power
to use through a relay? Bonus points are based on simplicity and
effectiveness. Extra credit is awarded if a shunt in the ACC is
identified that would accomplish the same purpose. Clever and innovative
applications of magnets on the monovalve are also acceptable. Good luck
class. The fate of a coupe is in your hands.
Why not just make it work as it was designed to work?
Marshall

You also might want to take a look at how much the USA benefits from the
'brain drain' of so many other countries. I heard part of that NPR program,
and from the part I heard it was talking about top students who would be a
help to this country. Take all of the 'foreign' physicians, chemists,
engineers, mathematicians, etc. out of the U.S. and see what happens. I
have a lot less problem helping the smart ones get an education here - and
learning about the USA and probably wanting to stay - than I do with the
waste in our public schools, forcing 90% of our kids to put up with rather
deplorable conditions in our middle and high schools, and even college,
because the other 10% have to be there, no matter how disruptive. I'd like
to see competitive exams for academic middle and high schools for anyone who
wants to go to them; vocational training and general information schools for
the rest. Tossing smart undocumented kids out or trying to keep them an
uneducated underclass, when it is our business who wants them here, is
working
