But could the classic resistor failure cause the fan to run while the

Er because it is connected to battery supply and lets current flow?

Errrr, on every car I've ever owned - and that goes back to a 1956 Ford,
and up to a 2005 Durango - if the key isn't in the Run position there is no
power to the HVAC system.

No kidding, but have you noticed how thinks like the interior lights, clock,
seats etc. still work when the key is out of the ignition. These are the
battery supply circuits, sometimes there may be more than one.

Certainly, but none of those are HVAC related, and none of them are downstream
of the dropping resistor module...

Does BMW source their electricals from Lucas? ;-)

Bosch normally, but perhaps they made an exception for this unit.
Incidentally the auxiliary fan still works after the ignition is off too.

Very common, but again, not HVAC, nor the dropping resistor...
