🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box fully and remove everything inside.
• Use flashlight to look along the right side of the glove box for a small “damper” arm (a small support that slows the glove box as it opens).

Step 2: Disconnect the glove box damper arm

• Use a trim removal tool (plastic pry tool) to gently pop the damper arm off its pin/peg on the glove box side.
• Go slow—this clip is easy to snap.

Step 3: Drop the glove box down

• With the glove box open, press the glove box sides inward (left and right) by hand to clear the built-in “stops.”
• Let the glove box swing down toward the floor.

Step 4: Remove the cabin filter access door

• Behind the glove box opening, locate the cabin filter cover/door (a small rectangular panel).
• Use trim removal tool (plastic pry tool) to help press the tabs and pull the cover off.

Step 5: Remove the old cabin air filter

• Pull the old filter straight out by hand while wearing nitrile gloves.
• Note the airflow arrow direction printed on the filter (it must match the new one’s direction).

Step 6: Install the new cabin air filter

• Slide the new filter in the same way the old one came out (match the airflow arrow direction).
• Make sure the filter seats fully and isn’t folded or pinched.

Step 7: Reinstall the access door and glove box

• Reinstall the filter cover until the tabs click in place (push by hand).
• Lift the glove box back up, press the sides inward to pass the stops, and close it.
• Reconnect the damper arm using the trim removal tool (plastic pry tool) if needed to guide it onto the peg.

✅ After Repair

• Start the engine and run the fan on medium/high for 30 seconds to confirm good airflow and no rattles.
