🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Use your hands to open the glove box fully.
• Remove all items from inside the glove box.
• Use a flashlight if the area is dim.
• Keep small items in a cup.

Step 2: Disconnect the Glove Box Damper

• Look on the right side of the glove box for the small damper arm.
• A damper is a small plastic arm that slows the glove box as it opens.
• Use your hands to slide the damper arm off its small peg.
• Do not use pliers unless absolutely needed, because the plastic can break.

Step 3: Lower the Glove Box

• Use both hands to gently squeeze the left and right sides of the glove box inward.
• This releases the built-in stop tabs from the dash opening.
• Let the glove box swing downward slowly.
• Gentle pressure is enough.

Step 4: Remove the Cabin Filter Cover

• Use the flashlight to find the rectangular cabin filter access door behind the glove box.
• Use your hands to press the side tabs on the filter cover.
• Pull the cover straight off and set it aside.
• Note the airflow arrow direction on the old filter before removing it.

Step 5: Remove the Old Cabin Air Filter

• Put on nitrile gloves.
• Use your hands to slide the old cabin air filter straight out.
• Keep the filter level so dirt and leaves do not spill into the HVAC box.
• HVAC means heating, ventilation, and air conditioning.

Step 6: Install the New Cabin Air Filter

• Check the arrow printed on the new cabin air filter.
• On your Highlander, install the filter with the airflow arrow pointing down.
• Use your hands to slide the new filter fully into the slot.
• Make sure it sits flat and is not folded or crushed.
• Do not force the filter.

Step 7: Reinstall the Filter Cover

• Use your hands to reinstall the rectangular filter cover.
• Push until the side tabs click into place.
• Lightly tug the cover by hand to confirm it is locked.

Step 8: Raise and Reattach the Glove Box

• Use both hands to lift the glove box back toward the dash opening.
• Squeeze the sides inward slightly so the stop tabs pass back into place.
• Reconnect the damper arm by sliding it back onto its peg by hand.
• Open and close the glove box once to make sure it moves smoothly.

Step 9: Final Check

• Start your Highlander.
• Turn the blower fan on low, then medium, then high.
• Listen for rubbing, whistling, or rattling from behind the glove box.
• If you hear noise, turn the ignition off and recheck that the filter and cover are seated correctly.
