Power Flow Ventilation
Short answer: No — a fan motor with a fresh-air slide is the standard heater/vent system. Power-Flo Ventilation was a separate 1969 option (also 1969–70 full-size and mid-size Pontiacs/Buicks): two small blowers in the upper cowl that push air out the lower-corner dash vents even at a standstill.
The blower motors were the same as the rear defogger; the two-speed switch was marked “AIR / HIGH / LOW” (it looked like the power-top/antenna/defogger switches and went in one of the dash switch openings — 1969 Service Manual p.15-16, fig. 15-27). It was available factory or as a dealer accessory package. Genuine Firebird examples are very scarce — it was a cheap way to move air in cars where A/C wasn’t available (Ram Air IV, Sprint).
