🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove anything inside.
• Use a flashlight to look along the right side and back area so you can see the stops and the filter cover area.

Step 2: Unhook the glove box damper (soft-open arm)

• The glove box damper is the small arm on the right side that slows the glove box when it opens.
• Use your fingers (and the flashlight) to locate the damper where it clips to the glove box.
• Carefully pop the damper clip off the glove box pin (it should not require force).

Step 3: Drop the glove box down

• Use both hands to gently press the left and right sides of the glove box inward to clear the side stops.
• Let the glove box swing down toward the floor slowly.
• Use the flashlight to look behind the glove box for the cabin filter housing door.

Step 4: Remove the cabin filter cover

• Use your fingers to press the tabs on the filter housing cover and pull the cover straight off.
• Use a clean shop towel to wipe dust from the cover and surrounding area if needed.

Step 5: Remove the old filter

• Slide the old cabin filter straight out of the housing.
• Use the flashlight to check inside the housing for leaves/debris, then wipe what you can reach with a clean shop towel.

Step 6: Install the new filter (correct direction)

• Find the airflow arrow on the new filter frame.
• Install the filter so the arrow matches the direction of airflow (typically DOWN on your Highlander when installed behind the glove box).
• Slide it in straight; do not crush or bend the filter.

Step 7: Reinstall the cover and glove box

• Reinstall the filter housing cover by pushing it in until the tabs click.
• Lift the glove box back up and push the sides inward again to get past the side stops.
• Reconnect the glove box damper on the right side by snapping it back onto its pin.
