Your cabin air filter cleans the air coming through the HVAC vents (heat/AC). Replacing it helps airflow, reduces odors, and keeps dust/pollen out of the cabin.

Difficulty Level: Beginner | Estimated Time: 0.25-0.5 hours

• ⚠️ Keep your hands away from the passenger airbag area (upper dash); you’ll be working only at the glove box.
• ⚠️ If you use a flashlight near the glove box, don’t rest it on soft trim (heat can mark plastics).
• 🔋 Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and unload the glove box

• Open the glove box and remove everything inside.
• Use a small flashlight to look at the right side of the glove box for the “damper” arm (a small slow-down strap that lets the glove box open gently).

Step 2: Disconnect the glove box damper arm

• On the right side, gently pry the damper arm off its peg using a trim removal tool (plastic).
• A damper arm is a small link that slows the glove box so it doesn’t drop suddenly.

Step 3: Drop the glove box down

• Push inward on both glove box side walls (near the back corners) with your hands to clear the built-in stops.
• Let the glove box swing downward slowly.
• Go slow to avoid cracking the stops.

Step 4: Remove the cabin filter cover

• Behind the glove box, find the cabin filter housing cover (rectangular cover).
• Release the cover tabs by hand; if tight, use a trim removal tool (plastic) gently.
• If your cover uses a screw on your build, remove it with a Phillips #2 screwdriver.

Step 5: Remove the old filter

• Slide the old cabin filter straight out by hand.
• Keep it level to avoid dumping leaves/dirt into the blower box.
• Tip: pull slowly—debris often sits on top.

Step 6: Install the new filter (correct direction)

• Check the airflow arrow on the new filter frame.
• Install it so the arrow points in the same direction the old one was installed.
• If there’s no arrow reference, the common direction is AIRFLOW DOWN (toward the floor), but match the old filter orientation if possible.
• Slide the filter in until it sits fully and evenly (don’t crush the pleats).

Step 7: Reinstall the cover

• Reinstall the housing cover and snap the tabs back into place by hand.
• If equipped, reinstall the screw using a Phillips #2 screwdriver until snug (do not overtighten into plastic).

Step 8: Put the glove box back up

• Lift the glove box upward.
• Push the glove box sides inward again so the stops pass the dash opening, then release.
• Reconnect the damper arm onto its peg by hand; if needed, guide it gently with a trim removal tool (plastic).

✅ After Repair

• Start your A/C blower and cycle fan speeds 1–4 to confirm strong airflow.
• Listen for any ticking/rubbing sounds (a sign the filter isn’t seated flat).
• If there’s an odor at first, run fresh-air mode (not recirculation) for a few minutes.
