🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Release the Glove Box Damper

• Open the glove box fully and use the LED flashlight to locate the small damper arm on the right side.
• The damper is the small plastic link that lets the glove box lower slowly.
• Support the glove box with one hand. Use the plastic trim-removal tool to carefully unhook the damper arm from its attachment point.
• Do not force or sharply bend the plastic arm.

Step 2: Lower the Glove Box

• With both hands, press the upper left and right sides of the glove box inward until its stop tabs clear the dashboard opening.
• Slowly rotate the glove box downward. It can remain attached at its lower hinges.
• Use the LED flashlight to locate the rectangular cabin-filter access cover behind the glove box.
• Press one side inward at a time.

Step 3: Remove the Filter Access Cover

• Use your fingers to release the locking tabs on the filter access cover.
• If a tab is difficult to release, gently press it with the plastic trim-removal tool.
• Pull the cover straight outward and set it aside.

Step 4: Remove the Old Cabin Air Filter

• Put on the nitrile work gloves and safety glasses.
• Use your fingers to slide the old filter straight out. Keep it level so loose debris does not fall into the blower housing.
• Note the direction of the airflow arrow printed on the old filter before removing it completely.
• Use the LED flashlight to inspect the empty housing. Remove loose leaves by hand only; do not push debris deeper into the opening.

Step 5: Install the New Filter

• Check the new filter for an airflow arrow. Install it in the same direction as the original filter; on this Impala, the airflow arrow normally points downward.
• Use both hands to slide the filter evenly into the housing without crushing or folding its pleats.
• Make sure the filter sits completely inside the housing and its edges are not pinched.
• Airflow arrows show air movement, not filter orientation.

Step 6: Reinstall the Access Cover

• Position the filter access cover over the opening using both hands.
• Engage its locating edge, then press the cover until each locking tab clicks into place.
• Gently pull on the cover with your fingers to confirm it is secure.

Step 7: Reinstall the Glove Box

• Lift the glove box while pressing its upper sides inward with both hands.
• Guide the stop tabs back through the dashboard opening, then release the sides.
• Use your fingers or the plastic trim-removal tool to reconnect the damper arm on the right side.
• Open and close the glove box slowly to confirm that it lowers smoothly and latches securely.

✅ After Repair

• ✅ Start your Impala and run the climate-control fan through all speed settings.
• 👂 Listen for rubbing, fluttering, or unusual blower noise. If present, switch the fan off and confirm the filter is seated flat.
• 💨 Check that airflow from the vents is steady and that the access cover remains secure.
• 📅 Inspect the filter about every 12 months or 15,000-22,500 km. Sonīpat's dusty conditions may require more frequent replacement.
