Question type: Maintenance & Repair

about a month and a half ago and I brought it up to the service advisor, they
gave me a spray to spray into the vents all it did was mask the smell (not very
well either). I take very good care of the care, I did a deep detail inside the car
all the carpets and mats are free of odors. I've gone through the common
causes, cleaned the exterior of the vents, I typically turn the ac off before
turnign the car off with the exceptions of a few times, pulled the carpet up by
the glove box and checked for wet carpet from possible clogged ac drain,
there was nothing, checked the cabin air filter it was clean aside from some
dust that came right off, even tried meguiars car bomb it took out the smell for
about a week and a half and it was back. The smell is noticeable when first
getting in the car after its been sitting for a few hours(im not sure if the heat
outside is factor affecting something inside its been in the high 90s and 100s
this whole month, in SoCal. ) When the vents are turned on the air does not
smell. Ive checked for leaks coming in and there were none. Outside intake
vent is clear of debris, a few people recommended spraying it with lysol with
the ac on high and outdoor air mode on in case theres possible mold growing
on the evaporator coils, it worked for about two days, im thinking of trying Kool
it for that same approach. The fish like smell is strongest when  the car has
been sitting out in the heat for hours, which is unavoidable for me at work. Any
suggestions or personal experience with the problem would be appreciated!

You might have to remove the evaporator to have it deep cleaned, or you have a dead animal up inside the dash.
