Can You Open Dash Vents Without AC/Fan On?

[fish_guru]

On my old '07 Silverado I was able to turn the entire HVAC system off and press the vent selector button and open up the vents to the outside air without the compressor or fan being on. I like to do that on cool mornings.

 

I can't figure out how to do that on the new truck (High Country) or if it's even possible. If I turn off the AC and recirculate button I get outside air but the fan is still on. Can't seem to turn off the fan and have the vents open. 

 

Checked the manual but no luck.

 

Any ideas?

I ran the AC, shut it off and then cycled the recirc button. Seems to be bringing in outside air. Very gently but it’s venting and the fans are off.
