Had a smell like bad tunsfish! Looked up on the web and found it was a design issue in the ductwork. I sprayed Lysol down into the fresh air intake while the windows were open and the fan on and it removed the problem completly!
musty odor to exhaust fumes
it smells like crayons.. And has a weird mildewish odor
been dealing with this issues for at least three years now! Do I have to take the damn car apart on a weekly basis to keep it not stinky - I certainly can't afford to pay someone to clean it on a weekly basis - that's for damn sure!!!!!!!!!!!!11
