Yep as in turning the entire HVAC off, so no air being circulated into the car at all.Does "turning fans off" mean turning the whole climate system off, and thus not using the cabin heater?
I have heated seats which only take 1 mile of range (miss my Leaf's heated steering wheel).
Recall reading somewhere the reason the temp defaults to 22 is to ensure minimal battery usage. Presumably this is the optimal temp for not draining the battery & working the system hard. However, even this seems to have a big hit on range.
