Where is the cabin air filter located on a 2005 toyota sienna

If I read your post correctly, you car cranks but does not start. If so, could be a PATS problem. Try starting the car with your backup key.

Your vehicle does not have a cabin air filter (also known as a pollen or AC filter). Vehicles without cabin air filters typically have a plastic mesh that prevents leaves and other foreign objects from entering the HVAC system. This mesh is part of the vehicle and does not need to be changed.

For 2005 Toyota Corolla (and Matrix), the location of the cabin air filter is inside of the drawer (passenger side). Open the drawer, you will see a screw on the RIGHT hand side. Unscrew it with a cross shape screw driver. Unlock the drawer from the screw holder. And take the drawer out of the cabin. After the removal, you will be able to see the location of the cabin air filter. There is a lock at each side of the filter cover. For each side, use two fingers to pinch the lock and pull out the cover. You will see the old filter after removing the cover. Pull it out, and insert your new filter.
Put the cover back. Make sure the two locks are firmly locked. Put the drawer back. To make this work easier, you may lock the bottom of the drawer first, as there are TWO locks on each side of the bottom drawer. Close the drawer to see if the position is right. Place the screw back, that's all

do you mean the cabin filter?
If you do, then the filter is located under the glove compartment or on the passenger side under the hood under a plastic shroud.

Check your manual.

Unfortunately, no.
Toyota began installing the cabin air filters in the Sienna product starting in 2003.
