🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box and remove everything inside.
• Use a flashlight to look at the right side of the glove box for the small “damper” arm.

Step 2: Disconnect the glove box damper

• The damper is a small slow-down arm that keeps the glove box from dropping fast.
• Use a trim removal tool (plastic pry tool) to gently pop the damper arm off its peg on the glove box (usually on the right side).
• Go slow—this clip is easy to crack.

Step 3: Lower the glove box

• Gently push inward on both side walls of the glove box to clear the built-in “stops.”
• Once the stops clear, let the glove box swing down toward the floor.
• Wear nitrile gloves if you’re sensitive to dust.

Step 4: Remove the cabin filter access cover

• Behind the glove box, locate the rectangular filter housing cover.
• Use your fingers or a trim removal tool (plastic pry tool) to press the side tabs and pull the cover straight off.

Step 5: Slide out the old filter

• Pull the filter tray/filter straight out toward you.
• Keep it level so trapped leaves and dust don’t spill.

Step 6: Install the new cabin filter

• Check the airflow direction marking on the filter (often an arrow labeled “AIR FLOW”).
• Install the new cabin air filter in the same direction as the old one came out.
• If there’s no arrow, match the orientation of the old filter exactly.

Step 7: Reassemble the glove box

• Reinstall the filter housing cover by pressing it in until the tabs click.
• Lift the glove box back up and push the sides in again to get the stops past the dash opening.
• Reconnect the damper arm to its peg (press it on by hand).

✅ After Repair

• Start the engine and run the blower fan at medium speed for 30 seconds.
• Check that airflow is stronger and there are no rattles behind the glove box.
• If you notice a “musty” smell, run A/C for a few minutes; the new filter may take a short time to settle.
