AC stinks like something died in the vents. What is this? What can be done about it?
See your dealer because your vehicule is under warranty
Maybe a squirrel/rat built a nest in your vent? Not covered by warranty. Maybe comprehensive on your insurance?
Well, if it smells like something died in your vent system then maybe something did. For sanitary reasons it needs to be looked into and cleaned out, but it will be on your dime, not the dealerships.
Rodents get into the smallest oddest spots.
