🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully by hand.
• Remove any contents so you can work comfortably.
• Use a flashlight to look along the right side of the glove box for the small “damper” arm (a little shock/strap that slows the glove box).

Step 2: Disconnect the glove box damper

• On the right side, gently pop the damper arm off its peg.
• If it’s tight, use a small trim tool (plastic) to help pry it off gently. (A trim tool is a plastic pry tool that helps prevent scratches.)

Step 3: Lower the glove box to access the filter door

• Push in on the glove box sides near the top to clear the stop tabs.
• Lower the glove box downward slowly until it hangs open.
• Tip: Push one side in at a time.

Step 4: Remove the cabin filter cover

• Behind the glove box, locate the rectangular cabin filter access cover.
• Press the tabs and remove the cover by hand.
• If needed, use the flashlight for visibility.

Step 5: Remove the old cabin air filter

• Slide the filter straight out of the housing by hand.
• Keep it level so debris doesn’t spill into the blower area.
• Check the filter for an airflow arrow and note the direction.

Step 6: Install the new cabin air filter

• Insert the new filter into the housing in the same orientation as the old one.
• Make sure the airflow arrow matches the correct direction (it’s usually marked “AIR FLOW” on the filter).
• Slide it in fully so it sits flat and doesn’t buckle.

Step 7: Reinstall the filter cover

• Reinstall the rectangular cover and snap the tabs in by hand.
• Give it a gentle tug to confirm it’s latched.

Step 8: Raise the glove box and reconnect the damper

• Lift the glove box back up, push the sides in, and let the stop tabs pass back into place.
• Reconnect the right-side damper arm onto its peg by hand.
• Open/close the glove box a couple times to confirm smooth operation.

✅ After Repair
