Chevrolet Camaro stopped using back windshield vents in order to reduce manufacturing costs of the newer model of cars. They had no significant function other than aesthetic.

air want blow out vents
Most vehicles have settings that allow for circulated air to function as a defroster, cooler, or heater, and can be adjusted to come out by the feet, the multi-directional vents (around chest level), and those near the windshield and windows (or sometimes a combination of those locations). The only setting where the air is only blown by the windshield is defrost.
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
