How to Install an ACC Cabin Filter on a 2003 Subaru Legacy GT
- 1). Open the glove box door and pry the two stoppers from the sides of the glove box door with a flat-head screwdriver. Allow the glove box door to hang downward by its hinges.
- 2). Remove the six screws from around the perimeter of the glove box insert with a Phillips screwdriver. Remove the two bolts on the bottom of the glove box insert with a ratchet and socket. Pull the glove box insert from the dashboard.
- 3). Press and hold the unlocking button on the blower motor resistor wiring harness and pull the wiring harness from the blower motor resistor.
- 4). Find the cabin air filter cover, the roughly 8-by-3-inch cover setting vertically on the air-conditioning box. Press the four L-shaped tabs the cabin air filter cover — two on top, two on bottom — toward the center of the cover to disengage them, then pull the cabin air filter cover off the air-conditioning box.
- 5). Pull the two halves of the cabin air filter — upper and lower — from the air-conditioning box.
- 6). Slide the shorter of the two halves of the new cabin air filter into the air-conditioning with the direction arrow pointing upward. Slide the second half of the cabin air filter on top of the shorter half, with its direction arrow pointing up and the tab on the bottom of the longer half inserted in the groove on top of the shorter half.
- 7). Set the cabin air filter cover on the air-conditioning box, lining up the L-shaped tabs with the slots in the air-conditioning box. Slide the L-shaped tabs toward the air-conditioning box to engage the tabs into the slots on the air-conditioning box.
- 8). Plug the blower motor resistor wiring harness back into the receptacle on the blower motor resistor.
- 9). Reinstall the glove box insert in its cavity in the dashboard. Tighten its six perimeter screws with a Phillips screwdriver and its two lower bolts with a ratchet and socket.
Lift the glove box door upward until it’s about halfway into the dashboard, then press the glove box door stoppers into their holes in the door assembly until they snap into place.
