🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Use nitrile work gloves to remove everything from the glove box.
• Use an LED flashlight to locate the small glove-box damper arm on the right side. The damper is the short link that makes the glove box open slowly.

Step 2: Disconnect the Glove-Box Damper

• Use your nitrile-gloved fingers to gently pull the damper arm sideways off its plastic mounting pin.
• Do not pry it with a screwdriver; the plastic arm can crack.
• Support the glove box while releasing the arm.

Step 3: Lower the Glove Box

• Use both nitrile-gloved hands to press the left and right glove-box walls inward.
• Move the molded stops past the dashboard opening, then carefully rotate the glove box downward.
• The lower hinges can remain connected; complete glove-box removal is unnecessary.

Step 4: Remove the Filter Access Cover

• Use the LED flashlight to find the rectangular cabin-filter cover behind the glove box.
• Use your nitrile-gloved fingers to press the cover’s locking tabs and pull the cover straight out.
• No screws or bolts are used, so there are no torque specifications for this repair.

Step 5: Remove the Old Filter

• Use your nitrile-gloved fingers to slide the old cabin air filter straight out.
• Before discarding it, use the LED flashlight to note its arrow marking and orientation.
• Keep the dirty filter level to avoid spilling leaves and dust into the blower housing.

Step 6: Clean the Filter Housing

• Use the LED flashlight to inspect the empty housing for leaves or loose debris.
• Use a vacuum cleaner with a 25mm crevice attachment to remove loose material near the opening.
• Do not push the attachment deeply into the housing because the blower fan is below it.
• Never use compressed air inside the housing.

Step 7: Install the New Filter

• Use nitrile-gloved hands to slide the new filter evenly into its guide tracks without crushing the pleats.
• If the filter is marked UP, install that arrow pointing upward.
• If it is marked AIR FLOW, install that arrow pointing downward, toward the blower motor.
• Confirm the filter sits flat and does not protrude from the housing.

Step 8: Reinstall the Access Cover

• Use your nitrile-gloved fingers to align the cover with the housing.
• Push it into place until both locking tabs click securely.
• Use the LED flashlight to verify the cover is seated evenly around its edges.

Step 9: Reinstall the Glove Box

• Use both nitrile-gloved hands to raise the glove box and press its side walls inward.
• Guide both molded stops back through the dashboard opening, then release the sides.
• Use your nitrile-gloved fingers to reconnect the damper arm to its mounting pin.
• Open and close the glove box slowly to confirm smooth operation.

✅ After Repair

• ✅ Start your Tundra and operate the blower at each speed.
• 🌬️ Confirm that airflow is steady and there is no rubbing, ticking, or whistling sound.
• 🔍 If airflow is restricted, switch the ignition off and verify that the filter is flat and correctly oriented.
• 📅 Inspect the filter approximately every 12 months or 16,000-24,000 km. Replace it sooner in Sonīpat’s dusty conditions.
• 🚫 No maintenance-light reset or scan-tool procedure is required.
