I can't be positive. But in both my 2003 4runner and 2008 Tundra it's located behind the lower glove box. It's the same procedure on both. Open the box remove the clip/rod on the right side of the box. Squeeze in on the sides of the box to bypass the stop tabs. Remove the glove box. Behind it you will find a long narrow trap door with clips on each end. Release them and pull out the cabin air filter.
That's it. Yours may be different. I found instructions in the box with a new cabin filter that I bought at a local auto store. $28.
Lower the glove box down remove the plastic cover on the heater box and pull out the cabin filter tray.
How do you replace cabin air filter in 1995 Toyota Previa?
to my knowledge, it has no cabin filter!
the cabin filter is located behind the glove box, just squeeze one side at a time the side of open glove box and pull down.
Access to it is located behind the glove box.
Which air filter are you referring to? The engine air filter, or the cabin air filter?
toyota sienna 2001
It doesn't have one. That car didn't come with a cabin filter.

There isn't one
