Hi everyone, I've been lurking here since I bought my 2019 G37 Journey Sedan, learning what I could about my car and the community, and now I have a question that I haven't been able to find an answer to. Intermittently, I will smell a gust of musty air come out of the air vents when I first start the car or turn on climate control after running with it off. It's a damp mildewy smell. It happens so infrequently that it isn't a big problem, but I finally decided to do something about it and bought a can of Ozium air sanitizer. I want to shoot a few blasts into the cabin air ventilation system, but I quickly realized I don't know exactly where it is. I have replaced the cabin air filer, so I suspect the intake is somewhere under the hood on the driver's side, but I'm not sure where or what plastic panels I might need to remove. Does anyone know where the cabin ventilation intake is?

 

Behind glove box. Remove door trim, drop lower glove box trim, undo 4 screws to drop glove box, drop down look at white panel that is behind that's cabin filter 10 min job

 

Its on the passenger side. you need to remove the plastic panel under the passenger wiper...so remove the wiper arms and the two plastic panels(i can remeber if you can just take off the passenger side only) and you should be able to see it looking down near the bottom of the windshield with the hood up

 

You mean a 2013 G37 right?

That momentary musty smell is a regular feature of our cars which I believe is due to left over condensation after using the AC. My remedy is to shut off AC about a mile before I get home in an effort to let the system "dry out" before parking the car.

If you've changed your own cabin air filter you know that it's on the passenger side behind the glove box - which means the cabin air intake is under the hood just behind the battery. But if you pull that cowling off to look you'll just be a few inches above the air filter so I don't think that's the source of the smell. It's more likely moisture around the refrigerant coils which are downstream of the fan and buried in the heart of the center console.

 

Get a can of bg fridgifresh and spray through fresh air vent at full blast with upper lower vents selected for 20 secs then switch to recirc and spray near feet vents for 10 sec let car run full blast with windows up for 5 mins. Repeat if needed

 

i agree with this fella. make sense. im pretty sure its not the filter bc i changed mine thinking it will fix the smell but it didnt. but the turning off thing early does help

 

Ah, Thanks for pointing out my typo. It’s actually a 2009 G37 Coup. My bad.
