🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the passenger-side lower dash area

• Open the passenger door and use a flashlight to look under/around the glove box.
• If a lower trim panel is in the way, remove any retaining screws using a 7mm socket and 1/4" drive ratchet.
• Use a trim removal tool (a plastic pry tool used to pop clips without scratching) to gently release clips and pull the panel down/out.

Step 2: Drop the glove box (if needed)

• Open the glove box.
• On the right side, disconnect the glove box damper arm if equipped (it’s the small slow-down arm). Use a trim removal tool to gently pop it off the peg.
• Squeeze the glove box sides inward by hand to clear the stops, then let the glove box swing downward.

Step 3: Remove the cabin filter cover

• Behind the glove box area, locate the rectangular cabin filter access door/cover on the HVAC case.
• Release the cover tabs by hand (or gently with the trim removal tool if tight) and remove the cover.

Step 4: Remove the old cabin air filter

• Slide the filter straight out.
• Keep it level as you pull it to avoid dumping leaves/dust.
• Note the airflow arrow before removal.

Step 5: Install the new cabin air filter

• Compare the new filter to the old one to confirm the same size.
• Install the new filter in the same direction as the old one, following the airflow arrow (typically points toward the rear of the vehicle, into the HVAC box).
• Make sure the filter seats fully and isn’t folded or pinched.

Step 6: Reinstall the cover and reassemble

• Reinstall the cabin filter cover by pressing it in until the tabs click.
• Lift the glove box back up and re-engage the side stops (squeeze sides inward again if needed).
• Reconnect the damper arm if you removed it.
• Reinstall any lower trim panel and tighten screws using a 7mm socket and 1/4" drive ratchet.
