Recirculating Air/Heat

Since the truck does not have a recirculate button, I was wondering if any of the positions on the selector switch recirculate air/heat?
Thanks!

There is a fresh air / recirculation door inside the HVAC box under the dash. 'Max AC' will set the system to recirculate.

Note that the temperature and air selection knobs are separate. You can set full heat and 'Max AC' at the same time and get full hot recirculating air.

It's not labeled very well.
