🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove manuals and loose items by hand.
• Use flashlight to see the right-side “damper” area clearly.
• The glove box damper is a small arm that slows the glove box from dropping.

Step 2: Disconnect the glove box damper

• On the right side of the glove box, locate the small damper arm.
• Carefully pop the damper arm off its pin by hand (no tools needed).
• Tip: Pull gently outward, then lift off.

Step 3: Drop the glove box down

• Press inward on both sides of the glove box to clear the side “stops.”
• Let the glove box swing downward slowly.
• Use work gloves if the edges feel sharp.

Step 4: Remove the cabin filter access door

• Behind the glove box, find the rectangular cabin filter cover.
• Press the cover’s side tabs and pull it straight off by hand.
• Use safety glasses in case debris falls.

Step 5: Remove the old cabin air filter

• Slide the old filter straight out by hand.
• Keep it level as you pull it out to avoid dumping leaves and dust.
• Use flashlight to inspect the filter housing for leaves.

Step 6: Install the new cabin air filter

• Check the airflow direction arrow on the new filter.
• Install it with the airflow arrow pointing down (toward the floor) for your Corolla’s typical HVAC layout.
• Slide it in evenly so it sits flat and doesn’t buckle.

Step 7: Reinstall the cover and glove box

• Reinstall the cabin filter cover by pushing until the tabs click into place.
• Lift the glove box back up and press inward on the sides again to re-seat the stops.
• Reconnect the glove box damper arm to its pin by hand.

✅ After Repair
