can some one tell me where the cabin filter is located?
Doesn’t the owner’s manual have this information?
my car was missing the manual when purchased used
Check with aftermarket filter suppliers. They might have instructions on their web sites or in the package.
How do you expect to own and maintain a complex vehicle like a Millenia without an owner’s manual?
They might have a used manual for you.
Go to Auto Zone, or similar store, if they have a cabin filter for your car they should be able to tell you where to install it. Many are behind the glove box.
