I have a bad smell coming inside the air vents. Sometime it smells like a bad septic tank other times like something died, but the smell is so strong it makes me sick. I had the care checked out and the mechanics said maybe something crawl in died inside the car. The removed the seats, carpet and dashboard and didn't find nothing. I told them the smell is coming from under the hood more by the passenger compartment filter. Do you know what this could be?

Have the same year and model as you with the same problem, but I have yet to have the dash removed to see if there is anything in there, but I think not. I Have a feeling that it is not caused by a dead animal rather something mechanical. I believe this becasue on a/c descharge hose that alows condensation to be drained from the car would be the only point of entry that say a mouse could get in, but it is not big enough, it the size of a dime!
