I'll take your word for it because I'm obviously not gonna hang out in the cold car to test this. My concern was not wanting to harm the engine in the long run only to take longer in fact to great the cabin.If you’re in AUTO mode on the HVAC, and the temp setting requires heating, the fan isn’t going to blow full speed until there is heat to blow. There isn’t any impact to how long the engine takes to warm up.
The system sends air to the floor and/or dash-top defrost vents when it decides heating is necessary, and through the dash front vents when cooling is necessary. It isn’t that complicated.
In regards to the HVAC vent selections... Is that how it actually works by default? Ideally that's how I would like it. In fact the only time I turn off auto is to supply more heat to my feet.
