🔧 Murano - Cabin Air Filter Replacement

Your cabin air filter cleans the air coming through the HVAC vents (A/C and heat). Replacing it helps 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 empty the glove box

• Open the glove box and remove any items inside.
• Use a flashlight to look along the right side of the glove box for the small “damper” arm (a little strap that slows the glove box). A damper is a small hinge/strap that controls the glove box drop.

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

• If you see the damper arm on the right side, gently pop it off its peg using a nylon trim removal tool.
• If it’s tight, work slowly so you don’t crack the plastic.

Step 3: Release the glove box side stops

• With the glove box open, press inward on the glove box sides near the top to clear the stops past the dash opening.
• Let the glove box swing downward carefully.

Step 4: Locate the cabin filter access door

• Behind the lowered glove box, use a flashlight to find the rectangular HVAC housing.
• Look for a small rectangular filter cover/door on the housing.

Step 5: Remove the cabin filter cover

• Release the cover tabs by hand. If needed, gently help the tab with a nylon trim removal tool.
• Set the cover aside where it won’t get stepped on.

Step 6: Remove the old cabin air filter

• Pull the filter straight out by its edge.
• Keep it level as you remove it to avoid dumping leaves/dust into the blower area.
• Tip: Slide a trash bag under it first.

Step 7: Install the new cabin air filter (correct direction)

• Check the airflow arrow printed on the filter frame.
• Install the filter so the arrow points in the same direction as the old one (typically DOWN toward the floor on this layout).
• Slide it in gently—don’t bend or crush the filter frame.

Step 8: Reinstall the filter cover

• Refit the cover and press until the tabs click into place.
• If screws are present on your cover variant, install them with a Phillips screwdriver #2 until snug (do not overtighten plastic).

Step 9: Reassemble the glove box

• Lift the glove box back up into position.
• Press the glove box sides inward again to pass the stops back into place.
• Reconnect the damper arm (if equipped) by pressing it back onto its peg by hand.
