🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Empty the Glove Box

• Use your hands to open the glove box fully.
• Remove all items from the glove box so nothing falls when it drops down.
• Use a small flashlight if the area is dark.

Step 2: Release the Glove Box Damper

• Look on the right side of the glove box for the small damper arm.
• The damper arm is a small plastic link that slows the glove box as it opens.
• Use your hands to slide the damper arm off its mounting pin.
• Pull gently to avoid cracking plastic.

Step 3: Lower the Glove Box

• Use both hands to press inward on the left and right sides of the glove box.
• This lets the glove box stops clear the dashboard opening.
• Slowly lower the glove box down toward the floor.
• No bolts are removed for this step, so no torque spec applies.

Step 4: Remove the Cabin Filter Cover

• Use your small flashlight to locate the rectangular cabin filter cover behind the glove box opening.
• Use your fingers to squeeze the tabs on both sides of the cover.
• Pull the cover straight out and set it aside.
• Remember which side faces outward.

Step 5: Remove the Old Cabin Air Filter

• Use your gloved fingers to slide the old cabin air filter straight out.
• Look at the airflow arrow printed on the old filter before removing it completely.
• On your Civic, the airflow direction should point downward through the filter.
• Dispose of the old filter if it is dirty, dusty, or smells musty.

Step 6: Install the New Cabin Air Filter

• Use your hands to slide the new cabin air filter into the slot.
• Make sure the airflow arrow on the new filter points downward.
• Push the filter in until it sits flat and fully inside the housing.
• Do not crush the filter pleats.

Step 7: Reinstall the Cabin Filter Cover

• Use your hands to align the rectangular cover with the filter housing.
• Push the cover in until both side tabs click into place.
• Gently tug the cover to make sure it is locked.

Step 8: Raise and Reattach the Glove Box

• Use both hands to lift the glove box back into position.
• Press the sides inward slightly so the stops pass back into the dashboard opening.
• Use your fingers to reconnect the right-side damper arm onto its mounting pin.
• Open and close the glove box once to confirm smooth movement.

✅ After Repair

• ✅ Start your Civic and turn the blower fan on low, medium, and high.
• ✅ Check that air flows normally from the vents.
• ✅ Listen for rattles behind the glove box, which could mean the cover is not fully clipped in.
• ✅ If the air still smells musty, run the fan with fresh-air mode on and consider cleaning the evaporator area with HVAC cleaner.
