What causes raw gas smell from heater vent on 2001 spectra?
im not sure its gas you smell. it could be but there is an extremely small chance of it being gas. fuel would have to be leaking into the air duct system some how and the two are not in any way connected. the air going into the cabin is completely separate from the air going into the engine. most likely its coolant. the heater core uses hot coolant from the engine to create heat if its leaking you'll smell it. other than a rotten smell from the ac that's about the only smell that would be in that system from the car itself. and that's caused by a dirty evaporator.-mechanic for 7+ years
