I have a problem with grass, dust, and other debris blowing from my vents when using fresh air settings. Is there a way to add a filter or something?

 

the only thing I would suggest is see if the dealer can replace the ventilation system filter with a HEPA filter (if they make one).

 

Is this all the time or only when driving through areas with a lot of debris in the air? My dad has had a similar problem on his Ram, believe it or not some creature got into the system a built a nest in the blower box in the passenger footwell. May want to check that, it's only a small possibility but I never believed it was possible till we opened his...

 

I first noticed this last year when hauling dead grass in the bed, the cab had gotten a lot blown on it while loading. This weekend my neighbor mowed and it was windy, covering my truck with grass and dust. Same thing, lots of grass clippings blowing from my vents. Where is the filter located? Maybe it is full.
