Musty Air
 

Hello All,
I am new to the Ford Forum, but have been a big Ford advocate for ages. I just bought a 2006 Freestyle Limited AWD. I love the vehicle, but when I turn on the vent, the air is musty. I was told it may need a new cabin air filter, but I don't believe it has one. Any suggestions on finding the source of the mildewy, musty smell?
