📋 Before You Begin

• 📍 Park your Suburban on level ground, select Park, and apply the parking brake.
• 🔑 Turn off the ignition, climate-control system, and blower motor.
• 📦 Empty the lower glove box so nothing falls out when it is lowered.
• 🔍 Compare the new filter with the old one before installation. Their dimensions and sealing edges should match.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lower the glove box

• Open the lower glove box fully and support it with one hand.
• Use your fingers to release the glove-box damper arm from the pin on the right side. The damper arm is the small linkage that makes the glove box open slowly.
• Press both glove-box sides inward to move the stop tabs past the dashboard opening.
• If a stop tab is tight, use the plastic trim-removal tool gently. Do not use a metal screwdriver.
• Allow the glove box to rotate downward carefully.

Step 2: Open the filter compartment

• Use the LED inspection flashlight to locate the rectangular cabin-filter cover behind the glove-box opening.
• Use your fingers to release the locking tabs on the filter cover.
• Pull the cover straight away from the HVAC housing. HVAC means the heating, ventilation, and air-conditioning system.
• No fasteners are removed, so no torque specification applies.

Step 3: Remove the old filter

• Wear nitrile work gloves and slowly slide the old filter straight out.
• Observe the airflow arrow printed on the old filter before removing it completely.
• Keep the dirty side facing upward to avoid spilling debris into the blower housing.
• Photograph the old arrow direction first.

Step 4: Clean the filter opening

• Use the LED inspection flashlight to check the compartment for leaves or loose dirt.
• Use the HEPA shop vacuum with crevice attachment to remove loose debris near the opening.
• Do not push the attachment deeply into the housing or contact the blower wheel.
• Do not use compressed air because it can drive debris farther into the HVAC case.

Step 5: Install the new filter

• Hold the new cabin air filter by its reinforced edges.
• Install it with the printed AIR FLOW arrow pointing downward, matching airflow through the Suburban’s HVAC housing.
• Slide the filter in evenly. Do not crush or fold the pleats.
• Confirm the filter sits flat and its sealing edges are fully inside the compartment.

Step 6: Reinstall the filter cover

• Position the cover over the opening by hand.
• Engage its locating edge first, then press the opposite side until every locking tab clicks into place.
• Use the LED inspection flashlight to verify there is no gap around the cover.
• No fasteners are installed, so no torque specification applies.

Step 7: Reinstall the glove box

• Lift the glove box by hand while pressing its sides inward.
• Move both stop tabs back through the dashboard opening, then release the sides.
• Reconnect the damper arm to the pin on the right side by hand.
• Open and close the glove box slowly to verify smooth operation.
