i dont believe the 3rd gens had a cabin air filter.... just guessing from the way the fan looks last time i cleaned it.

Yep,no cabin filter.

the cabin air filter is a recently new thing, just another filter to clean your air, it started in 2003 with the new model 4runners and it is under the glove box

I see this thread is almost 10 years old but when I turn the air on in my 99 runner a bunch of dust and such comes flying out, I thought the cabin air filter was just really dirty but seeing how there isn't one... who's got an idea?

Open up the blower fan and clean out the crapton of dirt in there. Here was mine:

Lol Looks like you suck up a chicken.

Maybe that's why my 4runner stinks so much, I've cleaned everything else.

I know what I’m doing this weekend! My a/c smells like dust!

So I know this is an old thread but just wanted to share in case anybody wanted to take it on. It takes some effort but this solution works flawlessly. Enjoying dust free air and interior cleanliness. Don’t know if I would do it again but I like a challenge and was determined to figure it out during the winter when I had some down time. Here is what I did.


-I removed plastic cowl
-The opening on the drivers side is an exact match shape wise to the section on the passenger side.
-I marked the area in the exact shape and used a uni biand saw to cut the access
-Air intake is oval with 1 flat corner on firewall side.
-I used a piece of aluminum and cut it large enough to cover the hole but small enough to clear wiper motor.
-I cut a square hole the exact dimensions inside the aluminum cover to accommodate a cabin filter for a 2016 - up Jeep Wrangler.
-I used 1” aluminum angle to make a filter rack and used heavy duty silicon the seal everything up.
-I checked clearance occasionally by turning wipers on.
-I temporarily sealed up the access hole with Butyl flashing tape not asphalt based due to odor
-I am working on a permanent solution for an access panel but the flashing is working great and is completely covered by the plastic cowl.

As stated above. It requires effort but is definitely not overly difficult This has been worth it due to the decreased dust and increased performance in cooling and defrost. I noticed minimal air flow drop on fresh mode. Obviously recirc mode is the same. Let me know if you have any questions.
