I'd agree w/ hursty but we don't all live in FL.
Actually, the ACC I servo tends to work OK except for the wet part (controls
coolant through heater core). I had a '79 TD that still used the electrical
and pneumatic circuits of the servo but a PO rerouted the heater core water
to bypass the servo and go through a manual valve to control flow. I just
opened the hood and adjusted the valve as needed when the seasons changed.
Eventually I restored all servo functions but the manual valve was not a bad
work-around.
Older manual climate 123s used a manual (cable operated) valve which would
be a great fix, IMO.
The weak points of the servo were the plastic chamber that cracked (due to
age plus thermal stress) and the O-ring that seals the shaft. There is a
metal replacement for the plastic chamber, and it's a good fix. But there
is no practical way to replace the o-ring, so when it goes, there is no way
to fix it and it usually damages the topside electrics.

this is a very good point. all of this stuff is because of the stupid temp
control and everyone just sets it to full blast and full blow anyway when
they are hot. what the hell use is an automatic system, particularly one
that sucks and breaks and now can no longer be fixed at reasonable cost?

there is no repair kit for that car. just leaking monovalves that cost
a
lot of money. it's not a great situation as if you get one from a
junkyard, it will likely either leak right away or lead pretty soon.
list
is like $640 nowadays from mercedes and bosch no longer makes/supplies
them
bosch doesn't even make the kits anymore for the 123 cars, which leaves
you
only with putrid chinese that will fail fast or genuine for 3 figures
