A tip for better AC-clean your box!

Well it's not just old cars, when I was working for the Cadillac/Olds dealer back in the day a customer came in with a nasty smell. New car & mouse nest, not only did it plug up the cores the mice got in the fan cage and it was all fun running around until the blower came on, then mice parts everywhere, and I had to clean it all up. Warranty void on that one.
