Abstract: An air freshener module is installed in a compartment slot formed in the dashboard of a vehicle. The module includes a body having a front section and a rear section. The rear section has an air inlet port that is adapted for coupling to the vehicle AC tube. The front section defines a plenum or interior housing space configured to receive an air freshener receptacle or holder that is movable between an open state and a closed state. The front end of the interior housing space defines an air outlet port. An air passageway extends between the air inlet port and the air outlet port. During operation, air admitted through the air inlet port is vented into the interior housing spaced occupied by the air freshener holder, enabling air to pass through an air freshener element and thereby communicate odorized air into the cabin. An adjustable closure regulates the amount of air delivered into the plenum.
