🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove all contents by hand.
• Use a flashlight to look at the sides of the glove box for the “stops” (the tabs that keep it from dropping all the way down).

Step 2: Release the glove box so it can swing down

• Gently push in on both sides of the glove box to clear the stops past the dash opening.
• If a small damper strap is attached on the right side, use a small flat trim tool to carefully pop it off its peg. (A damper strap is a small arm/strap that slows the glove box as it opens.)
• Let the glove box swing downward slowly and support it with your hand.

Step 3: Remove the cabin filter cover

• Behind the glove box, locate the rectangular cabin filter access door.
• Release the cover tabs by hand. If the tabs are tight, use a small flat trim tool gently to avoid breaking them.
• If your cover uses screws, remove them with a Phillips screwdriver #2 and set them aside.

Step 4: Slide out the old cabin air filter

• Pull the filter straight out by hand.
• Use a flashlight to check the filter slot for leaves/debris, then remove loose debris by hand (wear clean nitrile gloves).
• Tip: Note airflow arrow before removal.

Step 5: Install the new cabin air filter

• Insert the new filter into the slot by hand.
• Match the airflow direction arrow on the filter to the direction used by the old filter (typically “AIR FLOW” points downward toward the blower).
• Make sure the filter seats fully and isn’t folded or pinched.

Step 6: Reinstall the cover and glove box

• Reinstall the cabin filter cover by hand until the tabs click in place.
• If screws were removed, reinstall them with a Phillips screwdriver #2 (snug only; no published torque spec typically applies here).
• Reattach the damper strap (if equipped) by pressing it back onto its peg by hand.
• Swing the glove box back up and push the sides inward to pass the stops back into place.

✅ After Repair

• Switch between fresh air and recirculate to confirm no unusual noises from the blower area.
• If you notice a musty smell, run the heat for a few minutes to help dry the HVAC box.
