🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the glove box

• Open the glove box and remove any items inside.
• Use a small flashlight to look at the right side of the glove box for the small “damper” arm (a little strap that slows the glove box).

Step 2: Disconnect the glove box damper

• Carefully unclip the damper arm from the glove box using your fingers (use nitrile gloves for grip).
• Don’t yank—wiggle it off gently.

Step 3: Release the glove box stops

• On both sides of the glove box, squeeze the glove box walls inward so the “stops” can slip past the dash opening.
• Let the glove box swing down slowly.

Step 4: Remove the cabin filter access door

• Behind the lowered glove box, locate the cabin filter housing door.
• Press the side tabs and pull the door off by hand (use the small flashlight if you can’t see the tabs clearly).

Step 5: Remove the old cabin air filter

• Slide the old filter straight out.
• Keep it level to avoid dumping leaves and dust.

Step 6: Install the new cabin air filter

• Check the airflow direction arrow on the filter.
• Install it in the same direction as the old one (typically arrow points down toward the floor on this style housing).
• Slide the new filter in until it sits flat.

Step 7: Reinstall the housing door and glove box

• Reinstall the cabin filter housing door by pushing it on until the tabs click.
• Lift the glove box back up and squeeze the sides inward again to get the stops back into position.
• Reconnect the glove box damper arm by snapping it back onto its pin.
