🔨 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 to look along the right side of the glove box.
• Keep screws and papers away.

Step 2: Release the Glove Box Damper

• Use your hands to find the small damper arm on the right side of the glove box.
• The damper is a small plastic arm that slows the glove box as it opens.
• Gently slide or pop the damper arm off the glove box pin by hand.
• Do not pull hard; it only needs light pressure.

Step 3: Lower the Glove Box

• Use both hands to press inward on the left and right sides of the glove box.
• This lets the glove box stops clear the dashboard opening.
• Slowly lower the glove box down until you can see the cabin filter cover behind it.
• Press both sides evenly.

Step 4: Remove the Cabin Filter Cover

• Use your fingers to squeeze the tabs on the cabin filter cover.
• Pull the cover straight off and set it aside.
• Use a flashlight to check the direction arrow on the old filter before removing it.

Step 5: Remove the Old Cabin Air Filter

• Use your fingers to slide the old cabin air filter straight out.
• Hold it level so leaves and dust do not spill into the blower housing.
• The blower housing is the plastic box that holds the fan for your heater and A/C.
• Dispose of the old filter.

Step 6: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the slot.
• Match the airflow arrow direction to the marking on the filter housing or the old filter orientation.
• On most Toyota cabin filters, the airflow arrow points downward when installed.
• Make sure the filter sits flat and does not fold at the edges.
• Do not crush the filter pleats.

Step 7: Reinstall the Filter Cover

• Use your hands to align the cabin filter cover with the opening.
• Push the cover into place until the tabs click securely.
• Gently tug the cover by hand to confirm it is locked in.

Step 8: Reinstall the Glove Box

• Use both hands to raise the glove box back toward its normal position.
• Press the sides inward slightly so the glove box stops move back past the dashboard opening.
• Reconnect the glove box damper arm by pushing it back onto its pin by hand.
• Open and close the glove box once to confirm smooth movement.

✅ After Repair

• ✅ Start your Highlander and turn the blower fan on low, medium, and high.
• ✅ Check that air comes from the vents normally.
• ✅ Listen for unusual rattling, which could mean the filter cover is not fully clipped in.
• ✅ If airflow is weak, recheck that the filter is seated flat and facing the correct direction.
• ✅ Replace the cabin air filter about every 12 months or 12,000-15,000 miles, sooner in dusty areas.
