🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Empty and open the glove box

• Open the glove box and remove anything inside so it doesn’t spill.
• Use a flashlight to look at the right side of the glove box area.

Step 2: Disconnect the glove box damper

• On the right side, locate the small “damper” arm (a little shock/strap that slows the glove box).
• Use a plastic trim removal tool to gently pry the damper off its peg.
• Go slow—this clip is easy to crack.

Step 3: Release the glove box stops and lower it

• With the glove box open, press in on both sides of the glove box (near the upper corners) to clear the stops.
• Lower the glove box down toward the floor to expose the filter access door behind it.

Step 4: Remove the cabin filter cover

• Locate the rectangular filter cover behind the glove box.
• Release the tabs on the cover (some covers pinch off by hand; if tight, use a plastic trim removal tool gently).
• If your cover uses screws on your setup, remove them with a Phillips screwdriver #2.

Step 5: Remove the old filter

• Pull the filter tray/filter straight out.
• Wear nitrile gloves and tip the filter upward slightly to avoid dumping debris.
• Note the airflow direction arrow printed on the old filter (you’ll match this on the new one).

Step 6: Install the new cabin air filter

• Install the new filter in the same orientation as the old one.
• Match the airflow arrow on the filter to the direction shown on the housing (usually “AIR FLOW” arrow points downward on many Toyota/Lexus housings).
• Slide it in fully so it sits flat and doesn’t buckle.

Step 7: Reassemble the glove box

• Reinstall the filter cover until the tabs click (or reinstall screws using a Phillips screwdriver #2 if equipped).
• Lift the glove box back up and press the sides inward again to get the stops past the opening.
• Reconnect the damper arm to its peg by pushing it on by hand (use the flashlight to confirm it’s fully seated).

✅ After Repair

• Start the car and turn the A/C blower on medium.
• Confirm airflow is stronger and there are no rattles from the glove box.
• If you hear clicking, reopen the glove box and re-check the filter cover is fully latched.
