Car owners Nissan Primera generations P12 Often faced with the need to access internal electronics or replace the backlight. The procedure for removing the instrument panel requires care, since the plastic in the interior of this Japanese sedan becomes fragile over time. Incorrect actions can lead to squeaks or even cracks in the decorative inserts.
The main difficulty of the work lies in the hidden location of the fasteners and the presence of latches that are not visible during a superficial inspection. To avoid damage electronic unit control and not to break the latches, you must strictly follow the sequence of actions. In this article we will analyze in detail each stage of dismantling.
Preparing tools and workspace
Before you begin disassembling the dashboard, you need to prepare a suitable set of tools. For working with plastic elements Nissan Primera P12 It is best to use soft plastic or carbon blades to avoid scratching the paintwork. Metal screwdrivers can leave deep marks that will have to be masked later.
You will definitely need Phillips screwdrivers with a magnetic tip, as small screws tend to fall into hard-to-reach places. A set of wrenches or 10mm sockets will also be useful for removing the steering column if necessary to access the lower mounting bolts. Don't forget to prepare a container to store the unscrewed fasteners so as not to mix them up.

- 💡 Bright flashlight for illuminating hidden fasteners
⚠️ Attention: Before starting work, be sure to disconnect the negative terminal of the battery. This will protect the car's electronic system from short circuits if the contacts are accidentally touched.
Workplace organization plays an important role. If you are working in a garage, ensure there is adequate lighting, as many fasteners are in the shadow of the dash. Place a carpet or cardboard on the floor so that if parts fall, they will not break the floor or be scratched.
Removing the steering column and steering column switches
To gain access to the upper and side mountings of the instrument panel, it is often necessary to lower the steering column and remove the decorative cover. This allows you to have more room to maneuver and see hidden screws. B Nissan Primera The steering wheel is height adjustable, which simplifies the task.
First you need to loosen the steering wheel to gain access to the bottom of the dashboard. Pay attention to the location of the bolts: they may be hidden under plastic plugs. Carefully pry them off with a spatula and unscrew the fasteners. Do not use excessive force to avoid stripping the threads.
- 🔧 Loosen the steering column adjustment lever
- 🔌 Remove the plastic steering shaft covers (upper and lower)
- 🔩 Unscrew the screws securing the instrument housing
If you have cruise control or an airbag, be extremely careful when handling cables behind the wheel. The connectors may have special latches that must first be snapped off, and only then the plug itself must be pulled out. Security when working with pillows - priority number one.
Sometimes you have to remove the steering wheel itself to completely free access to the upper panel mounting bolts. This requires using a special puller or gently rocking the steering wheel after unscrewing the center nut. Do not hit the steering wheel with a hammer, this may damage the hub.
⚠️ Attention: If your vehicle is equipped with a driver's airbag, disconnect the battery and wait at least 15 minutes before touching the wires in the steering column area. The capacitor in the airbag system can store a charge.

Removing the center console and decorative trims
Center console in Primera P12 serves not only as an aesthetic element, but also as the main holder for part of the dashboard mounts. Removing it requires care, as there are a lot of clips that often break if you pry it off carelessly. You need to start from the top elements, gradually moving lower.
First, remove the climate control unit and radio, if they are in the access area. In some versions Nissan these elements are attached to the common frame of the dashboard. Use plastic spatulas to carefully go around the perimeter of the frame and release the clips. An audible click will indicate that the clip has disengaged.
After removing the console, access to the screws holding instrument panel from the sides. Pay attention to the location of the wiring: wires from the radio and cigarette lighter may interfere with complete removal of the console. Do not pull them with force, it is better to disconnect the connectors.
- 🔹 Carefully pry up the center console frame
- 🔹 Disconnect the button and radio connectors
- 🔹 Remove the decorative trim under the ashtray
☑️ Console removal steps
It is important to note that on automatic transmission models, the shift lever may also have fasteners that prevent complete removal of the console. If you cannot remove the part, check to see if the selector lever is locked.
Unscrewing the fasteners of the instrument panel
After removing the decorative trims, you will have a view of the main instrument panel mounting bolts. Usually their number varies from 4 to 6 pieces, located in the corners and center. IN Nissan Primera Phillips screws are often used, but hexagonal fasteners are also available.
Unscrew the bolts sequentially so as not to warp the panel. If a screw does not budge, do not use excessive force - check to see if it is clogged with dirt or the threads have been stripped. Use a quality bit that fits snugly into the screw head.
Pay special attention to the screws located at the bottom of the dashboard, they are often forgotten and when trying to remove the panel you can break the plastic. Conduct a visual inspection of the entire perimeter of the shield mounting. Sometimes it is necessary to remove the plastic trim under the glove compartment to access the lower mount.
| Screw location | Mounting type | Difficulty of access | Note |
|---|---|---|---|
| Upper part (above the steering wheel) | Cross PH2 | Average | Hidden under a cover |
| Sides | Cross PH2 | Low | Available after removing the console |
| Lower part (under the steering wheel) | Hexagon | High | Requires removal of the steering wheel cover |
| Central pillar | Cross PH2 | Average | Can be hidden under decor |
After unscrewing all the bolts, the panel is not yet ready to be removed. It is held on by plastic clips and connected to the electrical network. Do not try to immediately pull out the device, this will lead to a break in the wiring.
Disconnecting electrical connectors and removing the panel
The most critical moment is disconnecting the wiring harnesses. On the back of the dashboard Nissan Primera P12 There are usually two or three main connectors located. They come in different colors and sizes to avoid assembly errors. Gently press the connector latch and pull it towards you.
Pay attention to the location of the speedometer and tachometer: sometimes they have separate connections or sensors going to them. If you are planning to replace your light bulbs, this location will be the most convenient to access. Electronics Modern cars are sensitive to static electricity.
- 🔌 Press the connector lock and disconnect the plug
- 🔌 Check the condition of the contacts for oxidation
- 🔌 Carefully remove the panel from its seat
What to do if the connector is stuck?
If the connector does not budge, do not pull it forcefully. Try rocking it slightly from side to side, making sure that the latch is fully pressed. Sometimes using a small amount of silicone lubricant to ease removal helps, but do not use solvents.
Once the electrical connections are broken, the panel can be carefully removed. Movements should be smooth, without jerking. Make sure that the plastic does not touch the edges of the dashboard. It is best if the panel remains suspended until you completely free it from all snags.
In some cases, if you removed the steering wheel, you may need to remove the steering column cover to completely remove the shield. This is done so that the wires are not stretched during dismantling. Never pull on wires unless the panel is completely free of its mechanical fasteners.
Before disconnecting connectors, take photographs of their location and markings. This will help you put everything back together quickly and correctly, especially if the connectors look the same.
Installation and reassembly
Installation of the dashboard is carried out in the reverse order. First, connect the electrical connectors until you hear a characteristic click. Make sure the latches on the plugs are locked. Then carefully insert the panel into the seat, aligning the holes with the screws.
Tighten the mounting screws evenly without over-tightening them. Plastic Primera may burst under excessive force. Check to see if the panel is skewed relative to the dashboard. If there are gaps, loosen the screws and align the position.
After securing the shield, install the decorative trims and center console. Insert the clips into place until they click. Connect the battery and check the operation of all instruments: speedometer, tachometer, emergency system indicators.
The correct assembly sequence is: connecting connectors → fixing screws → installing decorative elements → checking functionality.
If after assembly an error message appears on the panel or some sensors do not work, check that the connectors are securely connected. Perhaps one of the contacts did not reach the end. In this case, you will have to repeat the disconnection and connection procedure.
Frequent mistakes and advice from professionals
Experienced craftsmen note that the most common mistake when removing a panel is trying to move it from its place before all the screws are completely unscrewed. This leads to cracks in the plastic case. Always check for hidden fasteners, especially at the bottom of the dash.
Another problem is the loss of small screws and clips. Use a magnetic tool or sorting containers. A forgotten screw can cause the panel to vibrate and make unpleasant sounds while moving.
When working with electronics, it is important not to mix up the connectors. Although they have a form that prevents incorrect connection, it is still better to double-check the markings. Unreliable contact can cause glitches in the operation of devices or even failure of the ignition system.
How to avoid squeaks after assembly?
Before installing the plastic pads, treat the contact areas with silicone grease or special paste. This will prevent unpleasant sounds from occurring when the body vibrates.
If you plan to replace the lamps, do so immediately after removing the panel. This will save time since you won't have to disassemble the dashboard again. Use lamps with the correct base and wattage to avoid overheating the reflector plastic.
What to do if the instrument panel cannot be removed?
If the panel does not budge, check to see if there are any screws left unscrewed in hidden places (under the glove compartment, behind the steering wheel). Also make sure that all plastic clips are unlatched. Sometimes gently rocking the panel helps, but without using force.
Do I need to disconnect the battery before removing it?
Yes, this is a mandatory safety requirement. Disabling the battery prevents short circuits and airbag deployment if contacts are accidentally touched.
How long does it take to remove the panel?
For an experienced master, the work takes about 40-60 minutes. The first time you try and there is no tool, it may take 2-3 times longer.
Is it possible to remove the panel without removing the steering wheel?
In most cases, it is not necessary to remove the steering wheel; simply lower the steering column and remove its plastic cover. However, this depends on the specific configuration of the car.
What to do if the clip breaks?
Replace the broken clip with a new one. You can use universal plastic clips of a suitable size, which are sold in car dealerships. Do not leave the panel on a broken clip as this will cause vibration.
