Been lurking this forum for awhile getting information from you all on things that I planned to do to 5th gen. You have been a big help and didn't even know it

Anyway, I searched the forums for information regarding a smell I have when I turn my AC on and couldn't find anything. It's not a burning smell or anything like that. Just a musty, stinky smell. It only lasts a little while and is worse when I have the AC on recycled air. I have noticed that I still smell it sometimes when I have the AC off and am using fresh air and the fan.

My wife had the same issue with her 4th gen before we got rid of it. Any ideas as to what it could be and how to get rid of it?
