🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and “drop” the glove box

• Use your hands to open the glove box all the way.
• Gently push in on both sides of the glove box to clear the side stops, then let it swing downward.
• If a small damper strap is attached on the right side, use a trim clip remover (non-marring) (specialty) to carefully pop it off. Go slow to avoid breaking clips.

Step 2: Remove the cabin filter access door

• Look behind the glove box area for the rectangular cabin filter cover.
• Use your fingers (or a trim clip remover (non-marring) (specialty) if tight) to release the locking tabs and remove the cover.
• Use a flashlight so you can clearly see the tab locations.

Step 3: Pull out the old cabin air filter

• Put on nitrile gloves and use safety glasses.
• Slide the old filter straight out. If it catches, wiggle it gently—don’t force it.
• Note the airflow direction arrow on the filter (it must match when installing the new one).

Step 4: Install the new cabin air filter

• Use your flashlight to find the airflow arrow marking on the HVAC housing or match the direction of the old filter.
• Slide the new filter in fully and evenly so it seats flat.
• If it buckles, pull it out and reinsert.

Step 5: Reinstall the cover and glove box

• Reinstall the access door by pushing it in until the tabs click into place.
• Reconnect the glove box damper strap (if equipped) using the trim clip remover (non-marring) (specialty) to guide it back on.
• Lift the glove box back up and push the sides in again to pass the side stops, then close it normally.

✅ After Repair

• Start the car and run the HVAC fan on medium, then high, to confirm good airflow.
• Switch between A/C and heat to ensure there are no new noises (a cover not fully clipped can rattle).
• If you still smell musty odor, run fresh air (not recirculation) for a few minutes.
