... nope!  On both my '83 QTC and the '85 4kSQ whenever the air conditioning
is turned on the source for the inlet air for the HVAC box is switched from
fresh to recirculate.  Since neither car currently has a functional A/C I do
find the function useful when driving in ... shall we say ... the more
agricultural regions of California ...
