In all seriousness: Is there any way to turn the interior fan off? The fan speed control knob seems to only go down to 1 and there’s no obvious on/off switch.

Well, on mine (dual zone) you press the left knob marked with the power symbol to turn the system off. There are several different hvac systems so I don't know if they all have the knob.

Fan is normally on low for air circulation , its an O2 thing , probably some thing EPA, NTA or one of the other alphabet agency's

I thought the question was to shut just the Fan off , not the system . I guess I misunderstood the question .

Good point, actually!

In-vehicle HVAC systems don't have an "idle-but-powered-on" state, which is different from fixed location (building) systems, where the UI (thermostat, etc…) still provides set-point temperature information (and sometimes more information) even if the system (fan / heater / AC) aren't active.

Modern vehicles don't seem to have much passive flow-through ventilation (minus the 2x60 or 4x60 roll-down-the-windows and drive-fast method), so there isn't appreciable airflow unless the HVAC fan is powered-on, so displaying the set-point temperature when the system has a zero-RPM fan state isn't terribly useful.

I could see surfacing the in-cabin temperature readings (which are different than the set-point temperature) in a UI that is always-on, but they elected not to do this.
