đź”§ Trax - Cabin Air Filter Replacement
Your Trax cabin air filter cleans the air going into the HVAC system (A/C and heat). Replacing a clogged filter improves airflow, reduces musty smells, and can help the A/C work better.
Difficulty Level: Beginner | Estimated Time: 0.25-0.5 hours
⚠️ Safety & Precautions
- Turn ignition OFF and remove the key/fob from the vehicle.
- Work gently around glovebox plastics to avoid breaking tabs.
- Do not start the blower with the filter removed (can pull debris into the HVAC case).

đź“‹ Before You Begin
- Park your Trax on level ground and set the parking brake.
- Move the passenger seat back for more working room.
- Empty the glove box so nothing falls out when it drops.
🔨 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.
- Use a flashlight to look at the right side of the glove box for the small “damper” arm (a little control arm that slows the glove box as it opens).
Step 2: Disconnect the glove box damper
- Use a nylon trim removal tool set to gently pry the damper arm off its pin (if it’s a clip-on style), or use a Phillips #2 screwdriver if there’s a small screw (some builds vary).
- Go slow—plastic clips can snap.
Step 3: Release the glove box stops and lower it
- Put on nitrile gloves and safety glasses.
- Push inward on both sides of the glove box to clear the side “stops.”
- Let the glove box swing downward toward the floor.
Step 4: Remove the cabin filter access cover
- Behind the glove box, locate the rectangular cabin filter cover.
- Use a nylon trim removal tool set to press the locking tabs and pull the cover off.
Step 5: Remove the old cabin air filter
- Slide the old filter straight out by hand.
- Use a flashlight to check for leaves/debris in the filter slot.
- If debris is present, remove it carefully by hand while wearing nitrile gloves.
Step 6: Install the new cabin air filter
- Match the airflow direction arrow on the filter to the airflow marking on the HVAC housing (typically it points downward in this setup).
- Slide the new filter in evenly so it doesn’t fold or crush.
Step 7: Reinstall the cover and glove box
- Reinstall the cabin filter cover by hand until the tabs click.
- Lift the glove box back up and push inward on the sides again to pass the stops back into place.
- Reconnect the damper arm using the nylon trim removal tool set (or Phillips #2 screwdriver if your damper uses a screw).
âś… After Repair
- Start the engine and run the HVAC blower on medium for 30 seconds.
- Confirm airflow is stronger and there are no rattles from the glove box area.
- If you notice a whistle, re-check that the filter is fully seated and not bent.
