Step-by-Step Instructions

Follow these steps carefully

Prepare the passenger footwell

On the 2020-2024 Cadillac XT6 the cabin air filter is located directly behind the glove box in the HVAC housing, accessed from inside the cabin; nothing under the hood needs to come apart.

Drop the glove box bin past its stops

Push the left and right sides of the open glove box inward toward the center and let the bin swing down on its lower hinges.

Release the filter cover tabs

Depress the tabs inward with your fingertips and pull the cover downward and toward you to remove it. On this vehicle the cover pulls downward than straight out, so hook the motion as a downward pull to avoid snapping a tab.

🔧 Mechanic's note — Ray Delgado

I do this every single time: On this vehicle the cover pulls downward rather than straight out, so hook the motion as a downward pull to avoid snapping a tab.

Extract the old filter

Slide the old filter out of its slot and take a close look at it. Check the airflow arrow printed on the old filter's frame and make a mental note of its direction before you dispose of it.

Slide in the new filter with correct orientation

Hold the new filter up to the housing and slide it straight into the slot with the airflow arrow pointing in the same direction as the old one. Push it in evenly until it is fully seated at the back of the slot.

Reinstall the cover and swing the glove box home

Then lift the glove box bin back into the dash opening, squeeze the sides inward to clear the stops, and close the door. Cycle the glove box open and closed to verify it latches and sits even with the dash.

Run the HVAC and confirm the fix

Check every vent for strong, even airflow and listen behind the glove box for whistling or buzzing, which means a tab is not latched or the filter is not seated squarely. Also try recirculation and lower speeds to confirm nothing rattles.

Here's what I do: Check every vent for strong, even airflow and listen behind the glove box for whistling or buzzing, which usually means a tab is not latched or the filter is not seated squarely.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Yanking the filter cover straight out instead of pulling it downward, snapping the retaining tabs.
• Tilting the new filter into the shallow slot and wedging a pleat, creating an air bypass that cuts filtration.
• Forgetting to rehook the glove box dampener arm, leaving the door to flop open under braking.

Tools You'll Need

Flashlight Clean rag for wiping the housing mouth

⚠️ Safety First!

• Keep fingers out of the housing while the blower could run; a spinning fan can catch a fingertip.
• Do not force stiff plastic tabs with metal tools; a cracked access cover will whistle at highway fan speeds.
