Do u have ur aircon set at recirculate all the time? if u do this could be ur prob, u have to set ur aircon/ heating at fresh air as much as possible otherwise the air in your cars heating/aircon can pump out stale air. When was the last time you had the pollen filter changed?
Hope I have been of some help to you.
