Apparently the Chevrolet Spectrum will warm you high-heeled boot for you. I am confused by the color change on the top slider. Does cold-cold air
only go toward your feet; is the defroster only hot air?

Why is it so clean

The only reasonable guess it traveled through a worm hole in the 1980s and ended up here in 2018. There is no other plausible explanation.

Interesting. It does make a certain sort of sense if you want to color-coordinate the upper/lower vents : if I’m cold, warming my feet is often vital, but if I’m hot, I want the cool air in my face.

See that plate on the front? Washington (state).
See where the CL ad is posted? Seattle
It might be the gentlest place on cars outside SoCal, plus rubber lasts forever (which it doesn’t in SoCal, but it doesn’t matter as much there because it rarely rains). As long as a car doesn’t leak, the paint isn’t absolute garbage from the factory, and it doesn’t get wrecked at some point (which is likely), it’ll look about like this in 32 years.

Damn. Haven’t seen one of those in forever. I thought they all got used up and tossed away years ago.

The colors on the top left slider are just a recommendation, since it makes more sense to use the floor
vents for heating instead of the upper vents. There’s nothing that prevents any vent from blowing whatever temperature you select through the bottom
slider. Also, the second position on the top slider is called bi-level; selecting that and setting the bottom slider to the middle position causes cold air to blow through the upper vents and hot air from the floor vents.

It’s entirely possible that the heater core and A/C evaporator are not a “sandwich” as is normal for a modern car, and are situated such that the floor vents and defrost only pass through the heater core. Unlikely, but would make sense in the case of the heater system being sort of modular and designed mostly for heat only. Most US cars at least until the late ‘60s were not designed for fully integrated A/C, and some of that psychology could have lingered - particularly with a downmarket captive import from an “A/C = luxury” market
and possible dash internals from ‘74.

This was actually my first hand me down car - albeit the turbo model and 5sp. manual -shown here in a mineral grey. The same color i once had. My friends used to call it the “rect??.... turbo” - you can fill in the blanks.

This was standard HVAC control design in the ‘80s. It moves from face to split (cool on your face, hot on your feet), to feet, to feet + defroster. People usually put heat on their feet in the winter to warm them up, thus the “warm” color on the feet.
I miss this simple design. Set the desired temperature, set the fan speed, then pick where you want it to blow - face, feet, combo or defrost . Modern controls are vague in comparison.

This is still confusing to me and both of our cars still have the 3 knob controls: position, fan speed, and temperature.

Top lever = position
Lower-right lever = fan speed
B ottom lever = temperature
