Ray Magliozzi says to use "Frigi-Fresh" spray.Brought this up a long, long time ago. Not a dead mouse lol. that's a good one though. I'm pretty sure that was a one-off deal rotfl
It's moisture build up in the cabin filter.. enjoy breathing your mildew spores...
But don't you worry, the nasty moldy smell will go away after about 3-6 months of dry weather. Or you could just replace it
One car is a Boxster and the other is an RX-8. I can vouch for the smell, it is horrid. I had asked my friend what kind of air freshener he was using, because it smelled like a dead animal. Lol. That's when he told me he had removed a dead mouse from the vent system, but the smell was lingering.Squidward - it must not be the rarest thing in the world if it happened to two of LotusCC's friend's cars. I'll tell ya though - that smell was no fun.
Now that you mention this particular scenario, indeed that would be more common than being than driving along with a mouse getting sucked into the fan blades and killed, fouling up the car. In fact, something similar happened on my own RX-8 as well. My car had parked for a month in the parking garage at my old workplace and a mouse had made a nest right on top of the air filter behind the right AC vent. I was replacing the filter and found all of the fibers that were torn away from my engine bay liner. No mouse, but a big ol' comfy nest. There was also rodent droppings underneath the car's air filter box which I hosed out.The RX-8 had been stored outside in a not so closed enclosure for the winter. He also found fur flying out of one of his vents on the high setting. That funk can still be smelled a year later as he has not removed the trespasser a year later.
Good to hear it's just a filter in this case
