Listen up.

On my 450SLC the centre dashboard vents suppy fresh air....from the outside.

The side vents supply heater air as do the floor vents.

When the AC is on the fresh air inlet is closed off and recirculated air is fed to the blower mtr so cool air is cooled cooler!

Later models may differ but I think that standard may have followed through , if there have been changes ...other than the fresh or rec option.
