1. Maybe time to change the cabin filter

2. Mold and Mildew spray. (Lysol spray may work fine)
Take out the cabin air filter (and possibly change it) spray up behind there well. Spray the filter. Spray into the vents, including floor vents, and where the air comes in outside by the windshield. Let the air-conditioner run for a little while.

3. Don't use re-circulation all the time.

4. Every so often, I do it once a month unless I forget, spray lysol into the vents.
