🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and clear the glove box

• Open the glove box fully and remove all contents.
• Use a flashlight to look along the right side of the glove box for the small “damper” arm (a little support strap that slows the glove box).

Step 2: Release the glove box damper (right side)

• If equipped with a clip-style damper, gently pop it off using a plastic trim removal tool.
• If your damper has a small screw, remove it with a Phillips #2 screwdriver, then unhook the damper.
• Go slow—this plastic can snap.

Step 3: Drop the glove box down

• Push in on both sides of the glove box (near the top) with your hands to clear the stops.
• Let the glove box rotate downward to hang open, giving access behind it.
• Use a flashlight to locate the cabin filter access door (a small rectangular cover).

Step 4: Remove the cabin filter cover

• Press the tabs on the access door and pull it off by hand.
• If the tab is tight, gently help it with a plastic trim removal tool—don’t pry hard.

Step 5: Remove the old cabin air filter

• Pull the filter straight out by hand (it may slide out horizontally).
• Wear nitrile gloves if it’s dusty.
• Use a flashlight to check the filter slot for leaves/debris and remove anything you can reach by hand.

Step 6: Install the new cabin air filter

• Check the airflow arrow on the filter frame.
• Install it in the same direction as the old one came out (the airflow arrow must point the correct way for your Altima’s housing).
• Slide it fully in so it sits flat and doesn’t buckle.

Step 7: Reinstall the cover and glove box

• Reinstall the cabin filter access door by hand until the tabs click.
• Lift the glove box back up and push the sides in to pass the stops again.
• Reconnect the damper on the right side; if it used a screw, install it with a Phillips #2 screwdriver (snug only—no overtightening).

✅ After Repair

• Start your Altima and run the blower on medium-high to confirm strong airflow.
• Switch between fresh air and recirculation to make sure nothing rattles behind the glove box.
• If you still smell musty odor, the A/C evaporator case may need cleaning.
