🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box and remove all items by hand.
• Use your flashlight to look along the right side for the small damper (a little arm/strap that slows the glove box).

Step 2: Disconnect the glove box damper

• On the right side of the glove box, gently pop the damper arm off its pin.
• If it’s tight, use a plastic trim tool (specialty) to carefully pry it off. Small pry, don’t twist hard.

Step 3: Drop the glove box down

• Push in on both glove box side walls with your hands to release the stops (the plastic “ears” that limit how far it opens).
• Lower the glove box fully so it hangs down.

Step 4: Remove the cabin filter access cover

• Behind the lowered glove box, locate the rectangular filter cover on the HVAC case.
• Use your flashlight to see the locking tabs.
• Press the tabs by hand and pull the cover off.

Step 5: Remove the old filter

• Slide the filter tray/filter straight out by hand.
• Keep it level to avoid dumping dust and leaves.

Step 6: Install the new filter (airflow direction matters)

• Check the new filter for an “AIR FLOW” arrow.
• Install it in the same direction as the old one (typically the arrow points down on the Corolla).
• Slide it fully in by hand until it seats evenly.

Step 7: Reinstall the cover and glove box

• Snap the filter cover back on by hand until both tabs click.
• Lift the glove box up and push the sides inward again to pass the stops back into place.
• Reconnect the damper arm to its pin by hand (use the plastic trim tool (specialty) only if needed).

✅ After Repair

• Start the engine and turn the fan to medium/high to confirm strong airflow.
• Switch between fresh air and recirculate to make sure the airflow sounds normal.
• If you hear rattling, re-check that the filter cover is fully clipped in.
