🔧 Murano - Cabin Air Filter Replacement

The cabin air filter cleans dust, pollen, and road debris from air entering your Murano’s heating and air-conditioning system. It is accessed through the front-passenger footwell near the center console; the glove box does not need to be removed.

Difficulty Level: Beginner | Estimated Time: 15-25 minutes

Assumption: These instructions apply to the stock U.S.-market climate-control housing.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Filter Housing

• Use the LED inspection flashlight and look beneath the dashboard from the front-passenger footwell.
• Find the narrow cabin-filter access cover on the side of the HVAC housing, close to the center console. HVAC means the heating, ventilation, and air-conditioning unit.

Step 2: Remove the Passenger-Side Lower Trim

• Use the plastic interior trim-removal tool to release the edge of the lower side trim beside the center console.
• Pull the trim gently outward to release its pressure clips, then place it somewhere safe.
• Do not twist the trim sharply; the retaining clips and panel can crack.
• Pull near each clip, not between clips.

Step 3: Remove the Filter Access Cover

• Use your gloved fingers to press the retaining tab on the filter access cover.
• Pull the cover away from the HVAC housing and note how its opposite end engages the housing.
• No fastener torque applies because the cover uses molded retaining tabs.

Step 4: Remove the Old Filter

• Use your gloved fingers to grasp the exposed edge of the old cabin air filter.
• Compress the filter slightly and pull it sideways through the narrow opening.
• Remove it slowly so trapped debris does not spill into the blower housing or carpet.
• Use the LED inspection flashlight to check the empty housing for leaves or large debris.
• Do not push tools or a vacuum nozzle deeply into the housing because the evaporator fins can be damaged.

Step 5: Check the New Filter Direction

• Compare the new filter’s dimensions and shape with the removed filter.
• If the new filter has an UP arrow, install it with that arrow pointing upward.
• If it has only an AIR FLOW arrow, match the arrow direction recorded from the original filter.
• Do not use the printed text alone to determine orientation; different filter manufacturers print their labels differently.

Step 6: Install the New Filter

• Use both gloved hands to compress the sides of the new filter gently.
• Guide it through the housing opening without crushing or sharply folding the filter media.
• Allow the filter to expand fully inside the housing.
• Use the LED inspection flashlight to verify that no filter edge is caught outside the opening.
• A gentle curve is normal during installation.

Step 7: Reinstall the Access Cover

• Use your fingers to engage the fixed end of the access cover first.
• Press the tabbed end toward the housing until it clicks securely into place.
• Tug the cover lightly by hand to confirm it is latched.
• No fastener torque applies because the cover snaps into place.

Step 8: Reinstall the Lower Trim

• Use the LED inspection flashlight to align every trim clip with its matching opening.
• Press the trim panel inward with your hands directly over each clip until it seats evenly.
• Check that the panel edges are flush and that no wiring or carpet is trapped behind it.
• No fastener torque applies because the panel is retained by pressure clips.

✅ After Repair

• ✅ Start your Murano and run the climate-control blower through all fan speeds.
• 👂 Listen for fluttering, ticking, or rubbing noises that could indicate an incorrectly seated filter.
• 💨 Confirm that airflow comes normally from the selected vents.
• 🔍 Recheck the access cover if airflow is weak or an unusual noise begins immediately after replacement.
• 📅 Inspect the filter about every 12 months or 15,000 miles, and more often in dusty conditions.
