Replacing light bulbs, repairing wiring or installing a new light fixture on Nissan Pathfinder The R51 generation often requires complete removal of the tail light. This procedure may seem difficult for a beginner due to the specific design of the body and the location of the fasteners hidden under the lining of the luggage compartment. However, if you know the exact algorithm of actions and have the right tool at hand, the task becomes quite feasible even in a garage.
Many crossover owners Nissan Pathfinder R51 are faced with the need to replace LED elements or eliminate problems with electronics glitches. Unlike older models, it uses a complex fixation system where there are no external screws and the main mounting points are located inside the trunk. Understanding this design is critical to avoid damaging the paintwork and fragile plastic latches.
In this article we will analyze in detail each stage of the work, from preparing the tool to the final installation of the device in place. We will pay special attention to the nuances of dismantling specifically for this model, since errors during removal can lead to the appearance of gaps or cracks in the body panels. If you plan to carry out the work yourself, carefully read the recommendations described below.
Preparing tools and workspace
Before you begin any physical impact on the car, you need to organize your workplace and collect the necessary set of tools. For Nissan Pathfinder series R51 you do not need a complex specialized service stand, but having a standard set of plumbing tools is required. Clear the trunk of any clutter to allow easy access to the inside of the fenders and trim.
You'll need a medium-sized Phillips screwdriver, preferably one with a magnetic tip, to prevent screws from falling into hard-to-reach car body cavities. Also, be sure to prepare a plastic spatula or a special dismantling wrench for removing decorative trims, since using a metal screwdriver can scratch the plastic trim. Don't forget to wear gloves, as working with wires and metal can be uncomfortable on your hands.
- 🔧 Phillips screwdriver PH2 for unscrewing the mounting screws.
- 🔨 Plastic spatula for carefully prying up the trim clips.
- 🔦 Flashlight with bright light to illuminate hidden cavities.
- 🧤 Protective gloves for working with wires and sharp plastic.
It is important to check the condition of all tools before starting work. Dull or bent bits can strip the screw splines, making removal much more difficult. Make sure you have access to electric lighting, as the interior of the trunk is often difficult to see.
Removing the interior trim of the luggage compartment
The first step is to dismantle the plastic trim in the part of the trunk where the light is located. On the model Nissan Pathfinder R51 The casing is attached using plastic clips and several screws. You need to carefully unfasten the panel to get to the back of the light fixture. Do this slowly to avoid breaking the fragile fasteners.
Start by looking for screws that may be under trim caps or in the recesses of the trunk handle. After removing the screws, you need to pry off the casing itself with a plastic spatula, starting from the bottom edge and gradually moving up. Be extremely careful with any wiring that may be connected to the inside of the panel.
⚠️ Caution: Do not use excessive force when snapping the clips off. If the panel does not budge, check for hidden screws, which are often hidden under the decorative elements of the trunk floor.
When the trim is detached from the body, it must be carefully moved to the side. You should not completely remove it unless absolutely necessary; it is enough to free access to the fastening elements of the flashlight. Make sure the trim does not pull on any sensor or license plate light wires that may be attached to it.
- 🔍 Inspect the trunk floor for hidden screws under the carpet.
- ✋ Smoothly pull the trim towards you, feeling the resistance of the clips.
- 🔌 Disconnect the backlight or sensor connectors if they interfere.
Access to flashlight fastening elements
After the trim is pulled back, you will see the metal body and the rear light mounting mechanism itself. On Nissan Pathfinder R51 Usually two or three screws are used to secure the device body to the body. There may also be a center pin present that requires additional attention during removal.
The screws may be hidden under small plastic plugs or located in deep recesses. Use a flashlight to find all the attachment points. If you don't see any screws, check to see if there are any under the trim pieces that may be glued or snapped in place. Clean the mounting points from dust and dirt so that the screws do not break off when unscrewing.

The process of removing the light fixture
When all the screws are unscrewed, you can move on to the most important stage - removing the lamp from the body opening. The body of the device is supported not only by screws, but also by guide pins, which are inserted into rubber seals. You need to smoothly pull the flashlight towards you without making sudden movements.
If the light does not budge, check for any missing screws or latches. Sometimes the plastic housing can stick to the body due to dirt or old seal. In this case, you can slightly rock the device from side to side, but without fanaticism. The main thing is to maintain the integrity of the plastic guides.
⚠️ Attention: Do not pull on the wires of the harness going to the lamp. This can lead to broken contacts or damaged insulation, which will lead to costly electrical wiring repairs.
Once you have the guides free, carefully move the light to the side to gain access to the power connector. Be careful with the shape of the body, as it has complex geometry and can get caught on the edges of the opening. If you are planning a replacement, immediately prepare a new location for installing the old device.
Disconnecting the electrical connector
After the light is disconnected from the body, but is still attached to the wires, you need to disconnect the electrical connector. On the model Nissan Pathfinder R51 The connector usually has a latch that you press or bend. Do not pull on the wire itself; always hold onto the connector body.
Inspect the condition of the contacts inside the connector. If you see oxidation or signs of overheating, this may be causing problems with the light's performance. In this case, it is recommended to clean the contacts or replace the entire connector. This may require a soldering iron and patience.
How to properly disconnect the connector?
Press the connector latch with your thumb and pull the two parts of the connector in different directions. If the lock is stuck, try to carefully pry it off with a thin screwdriver, but do this very carefully so as not to break the plastic of the lock.
If you are planning further wiring repairs, it is best to label the wires before disconnecting them. This will help avoid confusion when reassembling, especially if you are working in the dark or on multiple vehicles at once. Write down the color of the wires and their purpose.
- 🔌 Press the connector lock and carefully separate the parts.
- 🔍 Inspect the contacts for oxidation or damage.
- 📝 Write down the wiring diagram for easy assembly.
