Step-by-Step Instructions

Follow these steps carefully

Make room on the passenger side

Slide the front passenger seat back and empty the glove box, then turn the car off. The ATS gives no shortcut: the whole glove box has to come out to reach the filter housing behind it.

Drop the glove box past its stops

Open the glove box, squeeze both side walls toward the middle while pulling gently outward. The stops clear the dash opening and the box swings down past its normal position, hanging loose — exposing the screws around the frame.

Remove the seven glove box screws

Remove seven screws around the glove box frame: three along the bottom, four across the top. Support the box with one hand as you take out the last screws. Lift the box off its hinges and set it somewhere safe.

Pop off the filter cover

Find the filter cover on the HVAC housing. Pry its locking tab and pull the cover straight off. If the tab feels stiff, work it gently side to side — a snapped tab means the cover never seals.

Swap the filter

Compare the old filter with the new one — same size, pleat pattern, thickness. Note the old frame's airflow arrow direction before tossing it. Slide the new filter in with the arrow the same way, pushed fully home.

🔧 Mechanic's note — Tom Becker

Take a photo of the old filter's arrow before you pull it out. Half the cabin filters I see come back with weak airflow because the arrow went in backwards — a two-second photo beats guessing.

Reinstall the glove box

Set the glove box back on its hinges and reinstall the seven screws — four across the top first, then three along the bottom — snug but not gorilla-tight. Swing the box up past the stops until it clicks closed.

Verify the repair

Refit the filter cover so its tab clicks. Start the car and run the HVAC through every fan speed. Airflow should feel strong and even; a buzz usually means a screw isn't seated or the cover tab isn't latched.

All Done!

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

⚠️ Common Mistakes to Avoid

• Trying to reach the filter with the glove box merely lowered — on the ATS the box must be completely removed, or the housing stays hidden.
• Losing track of the seven glove box screws — keep the three bottom and four top screws separate so they go back in the right holes.
• Cracking the filter cover by prying the wrong edge; the cover releases through a single locking tab, not brute force.
• Reinstalling the filter with the airflow arrow flipped, which forces air through the media backward and cuts airflow.

Tools You'll Need

Phillips screwdriver (verify the screw head type on your glove box before starting)

⚠️ Safety First!

• Work with the engine off and the key out of the ignition.
• Wear a dust mask — a neglected cabin filter is packed with pollen and fine road dust.
• Watch for sharp edges on the exposed dash frame once the glove box is out.
