1. Match the sedan, manual and UP-marked replacement

This guide follows the US-market 2020 Corolla sedan glove-box and filter-tray arrangement on printed page 457 of the owner’s manual. Confirm the vehicle, production variant and replacement by VIN through Toyota’s parts system or a dealer; year alone does not select every filter option. Use a matched genuine-style cartridge marked UP for the procedure below. Park securely, apply the parking brake, switch the engine and blower off and empty the glove box. Stop if the actual arrangement differs.

2. Support the glove box and release its damper and claws

Open the empty glove box and support it so it cannot drop. Slide the damper eye off its peg if the vehicle has the damper shown in the manual. Press the glove-box side on the vehicle’s outer, passenger-door side inward to release its retaining claws. Then draw the glove box outward to disengage its lower claws. Work gently; do not pull the damper rod, force the hinges or remove the surrounding dashboard or airbag trim.

3. Remove the rectangular filter cover by its own latches

Locate the filter compartment behind the removed glove box and identify its separate rectangular cover. Compare the actual latch with the manual’s A release and B retaining-claw drawing. Release A, draw the cover out of the B claws and remove it, keeping track of its orientation. Do not treat the housing’s UP mark as an airflow arrow. Avoid nearby wiring and stop if a clip is broken, the cover does not release gently or the housing differs.

4. Withdraw the tray and contain the used filter

Slide the filter case straight out of the opening, noting how it sits and where its UP mark points. Keep the tray level so loose leaves and dirt remain on it rather than falling into the blower below. Lift the used filter from the tray and place it directly in a disposal bag without shaking it. Remove loose debris from the accessible tray gently; do not reach into the blower, spray cleaner into the housing or operate the fan with the opening exposed.

5. Fit the new cartridge with both UP marks upward

Confirm the replacement again before removing its protective packaging. Compare its perimeter and seating edges with the tray; fit it without crushing pleats, folding edges or leaving gaps. For the UP-marked cartridge used here, point the filter’s UP arrow upward and keep the case’s UP mark upward too. UP describes physical orientation. If the replacement instead says AIR FLOW, stop and use its vehicle-specific instructions; never automatically copy the UP arrow direction onto an airflow arrow.

6. Return the case and secure the filter cover

Slide the loaded case back into its original guides, keeping its UP mark upright and the filter seated evenly. Do not force a tray that catches; withdraw it and check alignment and cartridge fit. Refit the separate cover with its retaining claws engaged and latch it securely. Check that the cover sits evenly and cannot pull free with a gentle check. Do not switch the blower on until the case and cover are correctly installed.

7. Refit the lower claws, side retainers and damper

Support the glove box, align its lower claws with their original mounting points and seat them gently. Return the side retaining claws into position without bending them beyond the movement used for removal. Reattach the damper eye to its peg if fitted, without twisting or stretching the rod. Open and close the empty glove box slowly to confirm smooth support and a secure latch. Stop for a loose hinge, missing damper connection, rubbing or a lid that will not latch.

8. Test the blower while parked and record the change

With the filter cover and glove box closed, briefly use the normal ignition-ON, engine-off mode to test the blower at low and then another fan speed. Keep hands and loose items away from vents and listen for scraping or unusual noise. Check ordinary airflow without treating it as a filtration-performance test. Switch the vehicle and blower off afterward, return the glove-box contents and record the date and confirmed filter part. Investigate abnormal noise or restricted airflow before driving.

Final checks

Filter and case UP marks upright; cartridge seated without folds/gaps; tray and separate cover secure; glove-box lower/side claws and optional damper restored; smooth opening and latching; normal brief engine-off blower test. Record the actual confirmed part and date.

Where to find supplies

Production origin, equipment and part supersessions affect selection; use VIN confirmation instead of a universal part number. For an AIR FLOW-marked filter follow its own matched instructions. Stop for a different glove-box or tray arrangement, broken latch or persistent blower fault; obtain model-specific service support.
