check to see if your drain is plugged or not. then spary some air freshener on the vent outside the windshield. you may have a heater core leaking though. the drain is under the car you'll see a hose run something through it to make sure it's not plugged.

then have your coolingsystem pressure tested. your heater core may be leaking.
