where would you find out if the Air Conditioner filter is blocked on a 2005 Subaru Outback
There is no Power Steering Filter on a 2002 Subaru Legacy/Outback.
The Subaru Outback fuel filter is located inside of the fuel tank. Changing the fuel filter can be very costly and time-consuming.
The filter is behind the glove box. There is a video on wikihow.com that shows replacement and it requires removal of about a half-dozen panels including the glove box.
I found no mention of a power steering filter in the owner's manual or in the service manual for Outback.

The fuel filter is inside the gas tank, attached to the fuel pump.

It's on the right front side of the engine and accessible from under the car.
Bottom of the engine near the front. It points straight down.
