🔧 CX-5 - Cabin Air Filter Replacement

Your CX-5’s cabin air filter cleans the air that comes through the HVAC vents (A/C and heat). Replacing it helps improve airflow, reduces odors, and keeps dust/pollen out of the cabin.

Difficulty Level: Beginner | Estimated Time: 0.25-0.5 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

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

Step 2: Disconnect the glove box damper (if equipped)

• If you see a small arm on the right side, gently unclip it from the glove box using your fingers.
• If there is a small screw holding the damper, remove it with a Phillips screwdriver #2.
• Go slow—clips release with gentle pressure.

Step 3: Release the glove box side stops

• With the glove box open, press inward on both sides of the glove box (near the top edges) using your hands.
• While pressing the sides in, let the glove box swing downward past the stops.
• Use a flashlight to locate the cabin filter access door behind the glove box.

Step 4: Remove the cabin filter access door

• Find the rectangular access cover on the HVAC case.
• Press the side tabs and pull the cover off by hand.
• Set the cover aside where it won’t get stepped on.

Step 5: Remove the old cabin air filter

• Pull the filter straight out by hand.
• Keep it level as you remove it to avoid dumping leaves/dust into the blower housing.
• Wear nitrile gloves and safety glasses if the filter is very dirty.

Step 6: 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.
• If the filter has an airflow arrow, point it in the same direction as the original (typically toward the rear of the vehicle, into the HVAC box).
• If it won’t slide in, don’t force it.

Step 7: Reinstall the access door and glove box

• Reinstall the cabin filter access door by hand until the tabs click.
• Lift the glove box back up and press inward on both sides to pop it back past the stops.
• Reconnect the damper arm (and reinstall any screw using a Phillips screwdriver #2).

✅ After Repair

• Start your CX-5 and run the fan at medium-high speed to confirm good airflow.
• Turn on A/C, then heat, and listen for any ticking (a leaf stuck in the housing can cause noise).
• If airflow seems worse than before, re-check that the filter is seated and oriented correctly.
