Where does external air enter for the conditioner and heater on 1997 Chrysler LHS?

The 1997 Chrysler LHS's HVAC system draws outside air in through a series of vents located behind the grille in the front of the car. These aren't large, obvious openings, but rather smaller vents integrated into the grille's design. The air then passes through the system's air filter before being used for heating or cooling.
