🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box fully and remove any items inside.
• Use a flashlight to look at the right side of the glove box for a small “damper” arm (a damper is a small support arm that makes the glove box open slowly).

Step 2: Disconnect the glove box damper arm

• Use your fingers (wear nitrile gloves) to gently pop the damper arm off its pin on the glove box.
• Go slow—this clip is easy to break.

Step 3: Drop the glove box down

• With the glove box open, use your hands to gently push the left and right sides of the glove box inward to clear the stopper tabs.
• Let the glove box swing down toward the floor to expose the cabin filter housing behind it.

Step 4: Remove the cabin filter access door

• Use the flashlight to find the rectangular filter door (centered behind the glove box).
• Pinch the locking tabs and pull the door straight off by hand.

Step 5: Remove the old filter

• Slide the filter tray/filter out carefully by hand.
• Keep it level so dirt doesn’t spill into the blower area.

Step 6: Install the new cabin air filter

• Compare the new cabin air filter to the old one for size and shape.
• Install the new filter in the same orientation as the old one.
• If your filter has an airflow arrow, point it in the same direction as the arrow/marking on the housing (commonly “DOWN” for airflow).
• If it won’t slide in, it’s flipped.

Step 7: Reinstall the filter door and glove box

• Reinstall the filter door by pushing it on until the tabs click.
• Lift the glove box back up and push the sides inward again to get the stopper tabs back past the dash opening.
• Reconnect the damper arm to its pin by hand.
