Hi Pupule7
Thanks for your reply. As I mentioned in post #5, at the suggestion of another member I did find & replace the cabin air filter but the smell while a lot better is still bad. I leave my car in a garage all winter while away & a family of mice (I'm guessing) made a home in the duct work & the urine & crap has penetrated stuff. I have no idea where they got entry to the ductwork. After cleaning out the cavity all around where the cabin air filter slides into, I put a new cabin air filter in & after driving for just an hour or so I then removed the hour new cabin air filter & it stunk like hell already. I will give your Lysol suggestion a try but at $30 a pop for a cabin air filter, I will not replace it again until I can stop the bad smell.
