I don't need to use my A/C that often, but when I do, when I turn it off, there is a musty odor that lasts for a minute or two. There is no odor when the A/C is running, or at other times when A/C is off. It is not exhaust. Have had regular dealer service, and cabin air filter has been checked and replaced. Any thoughts? I live in San Diego, so humidity or mold is not likely an issue.
Thanks
