🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Open the glove box fully.
• Remove all contents by hand and set them aside.
• Use a flashlight to look along the right side of the glove box for the small damper arm.
• The damper arm is a small plastic support that slows the glove box as it opens.

Step 2: Disconnect the Glove Box Damper

• Use your fingers to gently slide the damper arm off the small pin on the right side of the glove box.
• No tool is usually needed. If it feels stuck, wiggle it gently instead of pulling hard.
• Go slow. Plastic clips get brittle.

Step 3: Lower the Glove Box

• Press inward on both sides of the glove box by hand.
• This lets the glove box stops clear the dashboard opening.
• Carefully lower the glove box down toward the floor.
• Do not yank it. The bottom hinges stay attached.

Step 4: Remove the Cabin Filter Access Cover

• Use your flashlight to find the rectangular cabin filter cover behind the glove box opening.
• Release the plastic tabs by hand and pull the cover straight off.
• Set the cover aside where it will not get stepped on.

Step 5: Remove the Old Cabin Air Filter

• Slide the old cabin air filter straight out by hand.
• Notice the direction of the airflow arrow before removing it completely.
• Use nitrile gloves if the filter is dirty or dusty.
• Use a shop vacuum with crevice attachment to gently remove leaves or loose debris from the filter slot.
• Do not push the vacuum nozzle deep into the HVAC box.

Step 6: Install the New Cabin Air Filter

• Check the arrow on the new cabin air filter.
• Slide the new filter into the housing with the airflow arrow pointing DOWN.
• Keep the filter flat so it does not fold or bunch up inside the slot.
• If it resists, pull it out and realign it.

Step 7: Reinstall the Filter Cover

• Push the cabin filter access cover back into place by hand.
• Make sure both plastic tabs click securely.
• No torque spec applies because there are no screws or bolts for this cover.

Step 8: Raise the Glove Box

• Lift the glove box back upward by hand.
• Press inward on both sides again so the glove box stops pass back into the dashboard opening.
• Let the glove box settle into its normal open position.

Step 9: Reconnect the Damper Arm

• Use your fingers to slide the damper arm back onto the pin on the right side of the glove box.
• Open and close the glove box slowly to confirm it moves smoothly.

• No scan tool, reset, or infotainment menu step is required.
