I just purchased a 2013 Chevy Malibu LTZ and every time I turn on the air conditioner, there is this horrible odor of rotten feet that comes out of the vent. The longer I run it, the stronger it gets. Can you please tell me what is causing this and what I can do about it. I am still under warranty and I just purchased the vehicle from a dealer on the 28 of February. It is a certified vehicle and I still have factory warranty on it as well.
Thanks for any help you are able to give me.
