🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Use your hands to open the glove box fully.
• Remove all items from inside the glove box.
• Use a flashlight to look at the right side of the glove box for the small damper arm.
• The damper arm is a small plastic link that slows the glove box as it opens.

Step 2: Disconnect the Glove Box Damper

• Use your hand to gently slide the damper arm off its small peg on the right side of the glove box.
• Do not pry hard; it should pop off with light pressure.
• Go slow with plastic parts.

Step 3: Release the Glove Box Stops

• Use both hands to squeeze the left and right sides of the glove box inward.
• The glove box stops are small molded plastic tabs that keep the glove box from opening too far.
• While squeezing the sides inward, lower the glove box down toward the passenger floor.
• No socket or screwdriver is needed for this step.

Step 4: Locate the Cabin Filter Door

• Use a flashlight to look straight behind the lowered glove box opening.
• You will see a rectangular plastic filter access door on the HVAC case.
• The HVAC case is the plastic housing for the heater and air conditioner system.

Step 5: Remove the Cabin Filter Door

• Use your fingers to press the side tabs on the cabin filter door.
• Pull the door straight outward and set it aside.
• No torque spec applies because this part clips in by hand.

Step 6: Remove the Old Cabin Air Filter

• Use your fingers to pull the old cabin air filter straight out of the housing.
• Watch the airflow arrow printed on the old filter before removing it fully.
• On this Outback, install the new filter with the airflow arrow pointing downward.
• Use a shop vacuum to remove loose leaves or dust from the filter slot if needed.
• Do not push debris deeper inside.

Step 7: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the housing.
• Make sure the airflow arrow points downward.
• Push the filter in evenly so it does not fold or crush.
• No torque spec applies because the filter slides in by hand.

Step 8: Reinstall the Filter Door

• Use your hands to align the cabin filter door with the opening.
• Push the door in until both side tabs click into place.
• Gently tug the door to confirm it is locked.

Step 9: Reinstall the Glove Box

• Use both hands to lift the glove box back upward.
• Squeeze both sides inward so the glove box stops pass back into position.
• Release the sides once the stops are inside the dash opening.

Step 10: Reconnect the Damper Arm

• Use your hand to snap the damper arm back onto the small peg on the right side of the glove box.
• Open and close the glove box slowly to confirm it moves smoothly.
