🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and empty the glove box

• Open the glove box and remove everything inside.
• Use a flashlight to look for the small “damper” arm on the right side (it’s a small soft-open link that controls how the glove box drops).

Step 2: Disconnect the glove box damper (right side)

• Gently pry the damper arm off its pin using a plastic trim removal tool or small flathead screwdriver.
• Go slow—this clip is plastic and should pop off without much force.

Step 3: Release the glove box stops and lower the glove box

• With both hands, push the left and right sides of the glove box inward to clear the “stops.”
• Let the glove box rotate downward toward the floor.

Step 4: Remove the cabin filter access door

• Behind the glove box, find the rectangular cabin filter housing.
• Press the locking tabs and remove the cover by hand; use the flashlight if needed to see the tabs clearly.

Step 5: Remove the old cabin air filter

• Pull the filter straight out of the slot by hand.
• Note the airflow arrow direction printed on the filter (usually “AIR FLOW” and an arrow).

Step 6: Install the new cabin air filter

• Slide the new cabin air filter into the housing in the same orientation as the old one.
• Make sure the airflow arrow matches the vehicle’s direction marking (or matches how the old filter sat).
• If it buckles, pull it out and re-seat it.

Step 7: Reinstall cover and glove box

• Reinstall the housing cover by hand until it clicks.
• Lift the glove box back up and push the sides inward again to pass the stops.
• Reconnect the damper arm onto its pin on the right side by hand (it should snap on).

✅ After Repair

• Start the vehicle and turn the blower fan to medium/high to confirm strong airflow.
• Cycle between fresh air and recirculation to confirm normal operation.
• If you hear a fluttering noise, the filter may not be seated flat—recheck it.
