Nissan Armada 2025-2026 Service and Repair Manual: Inspection Procedure
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
Cluster lid A and instrument panel
Acrylic lens and combination meter housing
Instrument panel to front pillar garnish
Instrument panel to windshield
Instrument panel mounting pins
Wiring harnesses behind the combination meter
A/C defroster duct and duct joint
CAUTION:
CENTER CONSOLE
Components to pay attention to include:
Shifter assembly cover to finisher
A/C control unit and cluster lid C
Wiring harnesses behind audio and A/C control unit
DOORS
Pay attention to the following:
Finisher and inner panel making a slapping noise
Inside handle escutcheon to door finisher
Wiring harnesses tapping
Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate many of these incidents. The areas can usually be insulated with felt cloth tape or insulator foam blocks from the Squeak and Rattle Kit (NI-50397) to repair the noise.
TRUNK
In addition look for the following:
Trunk lid dampers out of adjustment
Trunk lid striker out of adjustment
Trunk lid torsion bars knocking together
A loose license plate or bracket
MOONROOF/HEADLINING
Moonroof lid, rail, linkage or seals making a rattle or light knocking noise
Sunvisor shaft shaking in the holder
Front or rear windshield touching headlining and squeaking
SEATS
Cause of seat noise include:
Headrest rods and holder
A squeak between the seat pad cushion and frame
Rear seatback lock and bracket
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine/motor wall. The noise is then transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
Any component mounted to the engine/motor wall
Components that pass through the engine/motor wall
Engine/motor wall mounts and connectors
Loose radiator mounting pins
Hood bumpers out of adjustment
Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine/motor RPM or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or insulating the component causing the noise.
