I think this may help you. Yours may be in the same place.
I own both a 2003 4Runner and a 2008 Tundra, both have the cabin air filter located behind the glove box. My 4Runner owners manual gave examples on how to change it. It's easy.
I also got instructions on how to change it with a new cabin air filter that I bought at an auto parts store. ($29)
All I had to do was: (Open glove box)
1. Remove the catch on the right side of the glove box.
2. Squeeze in the sides of the glove box to bypass the catch on each side. let it open all the way.
3. Behind the glove box you will find a long trapdoor release the catches and pull it out. The filter is inside.
