Thermostatic temp setting - starting to get common in the early '80s.
Side-to-side split - Far from unusual by the mid '90s.
Auto fan - again, quite common.
But manual, not auto air direction? It's really only thermostatic aircon,
not full climate.
It's perfectly respectable but nothing special, by late '80s/early '90s
standards. By the mid '90s, it was a long way from cutting edge.
P'raps not. But there's plenty of more advanced, and has been for ages.
I reckon he's referring to stuff like the sun sensor and the velocity
sensor being tied into the climate control, so e.g. if the car is sat
with the sun beating down on it, it applied a bit of extra cooling. I
dunno if the Vectra had that. I can't see the point in the velocity
sensor, you're cooling the air in the moving car, are you not?
It says on the website that the point was to cool the car to the desired
temperature as quickly as possible and keep it there. The Vectra did
that, I've no complaints about the speed of cooling from the climate
control it had, not maintaining that level. It didn't heat up very
I don't know about the velocity sensor by my Octavia and the Bravo both had/have sun sensors on the dash that will affect how much cooling is used.
It was possible to demonstrate this quite easily by covering and uncovering it with a thermometer in the air vents
"I laugh in the face of danger , then I hide until it goes away"
I guess it'll depend, though. All climate control systems where the air
conditioning have cooled the interior quickly. Some have just been quieter
than others! :-) The 9-3 will get suitably noisy if you fire it up after
it's been sitting in the sun, but it quietens down much quicker than my
previous Saab. You can also change how this one behaves using the profiler.
Also, the 9-3's velocity sensor prompts the system to increase the fan speed
if the car is moving slowly and the effect is that the car anticipates an
increase in temperature, rather than reads an increase in temperature. Of
course, it doesn't do any anticipation at all, it's just designed to do it -
but it does it very well.
Indeedy, the Sports Saloon system does some other strange things - it
deliberately cycles warmer and cooler air, which gives the impression that
it's fresher in the interior and to keep people alert. There's the
directional sunshine bias, the night time bias (warmer feet, cooler head),
humid air bias (more for the windscreen - especially obvious when you go
through a rain shower in the summer or in fog). It doesn't have the by-seat
humidity sensors, auxiliary heater (reserved for the diesels in the Saab
range), heated seats (I have too pikey a spec'd model) nor does it
automatically switch on recirculation as the last BMW 5-Series I drove did,
Not as advanced as the system in my Alfa 156, which has fully automated
vent control - as did my B5 Passat.
My B6 had a similar system to the Scorpio, VW call it 'Climatic' (as
opposed to the fully auto Climatronic as fitted to higher spec/ cars)
and my current company hack has a similar system to Climatic.

Problem with the Scorpio system is normally the stepper motors cock up.
They're notorious on the Alfa 164 for the same thing (except in the Alfa
it's a days work to change some of them).
Actually, the 164 Lusso had full climate in '87.
My Volvo has full climate with all kinds of sensors, full distribution
control, fan control, dual zone etc. Works too.
Funnily enough it is the one really unreliable part of a Saab 9000 too,
the fan controller, the stepper motor temperature control and the
stepper motor vent operation. I had the fan controller fail terminally
and the temp controller be an intermittent fault.
