Weird smell

[Gencheezzy]

Hi so I bought a salvaged title hyundai genesis coupe 2013 but was fixed and everything. I I've noticed a weird smell coming in from the A/C vents when I turn on the a/c it doesn't smell but when it's just regular air there is a weird smell I also feel like I smell it after I turn off the car.

Well, a critter may have crawled up in there to make the A/C ducting its home and died. I had the same thing in a BRAND new 20016 Sonata from the dealer....found a damn mouse or some furry critter had made its nest in the cabin air filter area (it could not get thru the metal on the screen). It has packed in lots of 'vegetable material" (mesquite beans, etc) and that was the source of the smell. The dealer just kept spraying that deodorant into the ducts but I finally showed them when I pulled the cabin air filter.

So you did not describe the odor. Is more like petroleum (burning rubber, plastic, etc) or is it more of a biological nature.

IN any case, I'd pull the cabin filter and start there.

The smell may be due to mold formation on the evaporator coils.
