📋 Before You Begin

• 🅿️ Park your Tahoe on level ground and switch the ignition and climate-control system off.
• 📦 Empty the lower glove box so its contents do not fall out during removal.
• 🔎 Compare the new filter with the old one before installation. Their length, width, and thickness should match.
• 💡 Position a flashlight in the passenger footwell so you can see the glove-box fasteners.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the Lower Glove-Box Fasteners

• Open the lower glove box fully.
• Use a 7mm socket, 3-inch extension, and 1/4-inch drive ratchet to remove the glove-box retaining screws along the upper and lower edges.
• Place every screw in a small container so none are lost.
• Photograph the screw locations before removal.

Step 2: Remove the Glove-Box Assembly

• Support the glove box with one hand and gently pull it toward the passenger seat.
• If an edge remains caught, use a plastic trim removal tool to release it. A trim tool is a nonmetal pry tool that helps prevent scratches.
• Do not pull hard. If equipped with a glove-box lamp connector, press its locking tab by hand and disconnect it before moving the glove box aside.

Step 3: Open the Cabin-Filter Housing

• Use a flashlight to locate the narrow rectangular filter cover directly behind the glove-box opening.
• Press the locking tabs at the sides of the cover inward by hand.
• Pull the cover straight off without bending its plastic hinges or tabs.

Step 4: Remove the Old Filter

• Observe the airflow arrow printed on the old filter before pulling it out.
• Slide the old filter straight out by hand, keeping it level to avoid spilling debris into the blower housing.
• On your Tahoe, the replacement filter’s AIR FLOW arrow should point downward.

Step 5: Clean the Filter Compartment

• Use a vacuum with crevice attachment to remove loose leaves and dust near the opening.
• Keep the vacuum nozzle near the opening. Do not push it deeply into the housing because the blower wheel can be damaged.
• Do not use compressed air; it can drive debris farther into the climate-control system.

Step 6: Install the New Filter

• Hold the new cabin air filter with its AIR FLOW arrow pointing downward.
• Slide it into the housing by hand without crushing or sharply folding the pleats.
• Verify that the filter sits flat and does not extend beyond the housing opening.

Step 7: Reinstall the Filter Cover

• Align the filter cover with the housing by hand.
• Press the cover into place until both locking tabs click securely.
• Pull gently on the cover to confirm it is fully latched.

Step 8: Reinstall the Glove Box

• Reconnect the glove-box lamp connector by hand if it was disconnected.
• Align the glove-box assembly with the instrument-panel opening and press it evenly into position by hand.
• Start every screw by hand to prevent cross-threading.
• Use the 7mm socket, 3-inch extension, and inch-pound torque wrench to tighten the glove-box screws evenly to 2 Nm (18 in-lbs).
• Do not overtighten the screws because the plastic mounting points can crack.

✅ After Repair

• ✅ Open and close the glove box to verify smooth movement and proper alignment.
• 💡 Confirm that the glove-box lamp works if its connector was removed.
• 🌬️ Start your Tahoe and operate the blower at each speed. Listen for rubbing, fluttering, or unusual vibration.
• 🔍 If airflow is noisy, switch the blower off and confirm that the filter is flat and the cover is fully latched.
• 📅 Replace the filter approximately every 12,000-15,000 miles, or sooner in dusty conditions.
