I have a 2017 Hyundai Elantra. Recently it has been putting out a fishy odor coming through the air vents. It does not smell when the AC is on, only when air from the outside is being pushed through. What do I need to clean or replace? Thanks.
Get a can of Ozium at the auto parts store, turn your system on to vent, fan on high and spray it into your vents below the windshield, then change it to recirculate. Change your cabin filter and vacuum out any crud from its mounting location and get rid of the dead Carp in your back seat.
get rid of the dead Carp in your back seat.
I was going to say, it sounds like you made an enemy
Do you mean the carp or @mjb967?
hiding a fish in someone's vehicle is a well known form of revenge. And if you're really evil, you hide two.
