🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove all contents.
• Use a flashlight to look along the right side for the glove box “damper” (a small arm that slows the door).

Step 2: Disconnect the glove box damper

• On the right side, unclip the damper arm from the glove box using a trim removal tool (plastic) or small flathead screwdriver.
• Damper = the slow-open support arm.

Step 3: Lower the glove box door down

• Press inward on both sides of the glove box (near the stops) with your hands to let it drop down farther.
• If it feels stuck, use the trim removal tool (plastic) gently—don’t pry hard.

Step 4: Locate the cabin filter access door

• Behind the lowered glove box, use the flashlight to find the rectangular HVAC cover (this is the cabin filter door).
• If you do not see a filter door and see a solid HVAC case instead, your Tahoe may not be equipped with a cabin filter from the factory.

Step 5: Remove the cabin filter cover

• Release the cover tabs by hand. If needed, use the small flathead screwdriver to gently help the tab move.
• Pull the cover off and set it aside.

Step 6: Remove the old cabin air filter

• Slide the old filter straight out.
• Wear nitrile gloves—filters can be dusty.
• Use the flashlight to check for leaves/debris inside the slot and remove any loose debris by hand.

Step 7: Install the new cabin air filter

• Find the airflow arrow on the new filter frame.
• Install it in the same direction as the old one (airflow should point toward the blower/into the HVAC case).
• If it buckles, pull back and try again.

Step 8: Reinstall the cover and glove box

• Reinstall the cabin filter cover until the tabs click into place.
• Lift the glove box back up and press the sides inward to pass the stops back into position.
• Reconnect the damper arm on the right side by snapping it back on.

✅ After Repair

• Start your Tahoe and run the fan at medium/high for 30 seconds to confirm strong airflow.
• Switch between fresh air and recirculation to confirm the air direction sounds normal.
• If you hear a new ticking/rubbing noise, re-check that the filter is fully seated and not folded.
