🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and open the glove box

• Remove everything from the glove box so it can drop down fully.
• Use a flashlight to look along the right side of the glove box for a small “damper” arm (a little slow-down strap).

Step 2: Disconnect the glove box damper

• Gently pry the damper off its pin using a plastic trim removal tool (non-marring).
• Go slow—this plastic clip is easy to snap.

Step 3: Release the glove box stops so it drops down

• Press inward on the left and right sides of the glove box to clear the “stop” tabs.
• Let the glove box swing downward toward the floor.
• If a screw is present on your glove box limiter/trim, remove it with a Phillips screwdriver #2.

Step 4: Remove the cabin filter cover

• Behind the glove box opening, find the rectangular cabin filter housing cover.
• Unclip the cover by hand; if tight, use the plastic trim removal tool (non-marring) to help start the clip.

Step 5: Remove the old filter

• Slide the old cabin filter straight out.
• Use a flashlight to check inside the housing for leaves or debris and pull it out by hand (wear nitrile gloves).

Step 6: Install the new filter in the correct direction

• Look for the airflow arrow printed on the filter frame.
• Install it so the airflow arrow points down (toward the floor), which matches the Corolla’s airflow through the housing.
• Slide the filter in straight so it doesn’t crush or fold.

Step 7: Reinstall the cover and glove box

• Snap the cabin filter cover back into place by hand.
• Lift the glove box back up and push the sides inward again to pass the stop tabs.
• Reconnect the damper arm by pressing it back onto its pin.
• If you removed any screw, reinstall it using a Phillips screwdriver #2.

✅ After Repair

• Start the engine and run the blower on high for 30 seconds to confirm strong airflow.
• Switch between fresh air and recirculate to ensure nothing rattles behind the glove box.
• If there’s a new noise, re-check that the filter cover is fully clipped in.
