When I turn on my ac or fan on in my 92 miata the air smells badly Whats going on?

Answer 1

It is the same that happens on a lot of cars air conditioners. If the air conditioner is run on recirculate or max air conditioning, the condensor, the coils that deliver the cold, has moisture on them. When the car is shut off, the moisture does not have a chance to dry therefore mold and mildew form. Normally if you run the car on recirculate, if you go to outside air 5 or 10 minutes before you shut the car off, the condensor gets a chance to dry out and mildew will not form. If you car has been run quite a long time on recirculate, you might try running it for at least a week on outside air. It might clear your smell up. Otherwise go to a parts story and buy a spray, I can't recall the name, that is sprayed into the air intake by the windshield wipers. This is done while the fan or air conditioning is running. It is a chemical that kills the mildew. If you can't find it at a parts store, ask your dealer, any dealer, what they use. Hope this helps
