If u keep the temperature high it will blow warm/hot air through the vents even when the blower is off (using outside air flow with recirculation off). Same thing if u lower the temp to LO, it will blow a rather cold air through the vent but it won't be ice cold like when the whole AC system is on though.
So what is ur temp set at before u turn off the AC?

If you're manually using the HVAC unit (auto button is not lighten up), then it has nothing to do what the temperature is set imho.
You must have the "outside air" button pressed. Try pressing turning the "Off" and then pressing the "recirculating air" button instead. Apparently having the HVAC unit off and having the "outside air" button pressed STILL blows air out of the vents slightly.
I kinda hate when car HVAC units don't really turn fully "Off" after you press the appropriate button, so I had to experiment with this myself as well, hence why I know what the solution is
Try that out and report back,

You're correct. With the unit off, having the "outside air" button pressed still blows air, while switching to "recirculating air" stops it. Thanks!

In the pre-Auto HVAC days, The fan switch controlled only the fan, Recir control the flaps of letting in outside air and the temp **** controlled a valve of how much anti-freeze is sent thru the heater coil. This appears to be the same case except that now there are computerized adjustments when the AUTO button is on. Before AUTO functions I often just wanted the vents on to let in outside air (always kept it cool). IMO I prefer the way it is designed, I don't want it to "really turn fully 'Off'". It gives flexibility.
Glad the OP got their answer.
