Nissan 300ZX has really bad smell coming from ac vents.

SOURCE: 1986 Nissan 300zx ac only works when engine is iddling

the ac is supossed to slow down, it was a way for them to keep the torque there. there could also be a plug undone on the passenger side by the big black box there is a black container there for the ac that has two plugs one come unconected sometimes

I've had mice in my Nissan PU and actually caught one in a trap set on the floorboard; so I know they can get inside. They also knocked some of the fiberglass insulation into the blower motor so it vibrated as it was no longer balanced. You could have a dead one in your blower. Mine was easily accessible from under the passenger side under the dash. Three screws and the motor dropped so I could clean out the fiberglass.
