Musty smell from A/C vents
 

Each time I turn on A/C there is bad musty smell coming out from the vents. My friend says that it's because of mildew growing on A/C evaporator coil. What should I do to get rid of that smell?
Thanks guys.

Have you checked your cabin air filter? If it's got funk growing in it, that smell will get circulated through the cabin.

Happened to me once years ago (before cabin filters) when I parked my Integra at the airport after a long drive there, on an especially hot/humid day in early autumn. When I returned a week later, air coming from the AC vents smelled like limburger cheese/old socks. I just ran the fan at high speed for the next week, with a window cracked and the intake air control set to 'fresh'. The smell eventually faded, and everything went back to normal as the weather became dryer.
