Introduction
Rear windshield wiper on a compact hatchback Nissan Note Performs a critical function in providing driver visibility when reversing and in adverse weather conditions. Over time, the mechanism may jam, or the rubber edge of the brush will lose its elasticity, which will require urgent intervention. The dismantling process has its own design features, characteristic of the B0 platform on which the car is built.
Many car owners are afraid to remove the wiper themselves, for fear of damaging the plastic arch or the drive mechanism, but the procedure is quite simple if safety precautions are followed. In this article we will look at how to properly release the fastener without using excessive force, and what nuances should be taken into account when choosing a new spare part.
Unit design and preparation for work
Before you start physically affecting the unit, you need to understand how the rear wiper drive works on the Nissan Note different generations. The mechanism consists of an electric motor, a gearbox and a lever, which is rigidly fixed with a nut under a decorative plug.
It is important to prepare the necessary tools so as not to look for them during work, which can lead to accidental damage to the body. You will need a socket set, preferably one with a ratchet, as well as a flathead screwdriver for removing the plastic parts.
- 🔧 10 mm socket (main tool for removing nut)
- 🔨 A thin flat screwdriver or a special puller for removing clips
- 🛡️ A rag or soft cloth to protect the paintwork
- 🧤 Work gloves to protect hands from sharp plastic edges
It should be noted that on some modifications Nissan Note The fastening mechanism may differ slightly, but the general principle remains the same. Before starting work, make sure that the car is on a level surface and the handbrake is tightened.
Step-by-step instructions for removing the brush
The first step is to remove the decorative cover that hides the lever mounting nut. This cover is usually held on with plastic clips or simply put on with a little effort. Use a screwdriver to carefully pry it out so as not to scratch the paint around the glass.
After removing the cover, you will see a metal nut securing the wiper arm to the motor shaft. Carefully inspect the condition of the threads, as corrosion may make unscrewing difficult. Use a 10mm socket, but be careful not to overdo it to avoid stripping the threads.
☑️ Preparing to remove the wiper
When the nut is completely unscrewed, do not rush to suddenly remove the lever. It may be tightly stuck to the shaft due to oxidation. In this case, it is necessary to use a special puller or gently rock the lever from side to side, applying force strictly along the axis of the shaft.
If you plan to simply replace the rubber band, and not the entire mechanism, then after removing the lever, you can begin to disassemble the brush itself. However, on Nissan Note More often than not, the entire assembly changes due to the design features of the fastening.
Features of fastening on different generations
The first generation (E11) has a more massive mount, while the second (E12) uses a more compact system with a plastic bushing, which requires care when dismantling.
After removing the lever, clean the shaft of old grease and dirt before installing the new element. This will extend the life of the mechanism and ensure smooth operation.
- 🚫 Do not try to rip the lever with a sharp jerk, this may break the motor gearbox
- ✅ Use WD-40 or similar penetrating lubricant for stuck joints
- 📝 Note or photograph the position of the lever before removing
Common mistakes and how to avoid them
The most common mistake made by beginners is trying to remove the lever by force without first unscrewing the nut or using a hammer. This is guaranteed to lead to damage to the drive shaft or the motor housing itself, which will require expensive repairs.
Another problem is choosing the wrong length of the new brush. On Nissan Note The rear wiper has a specific length, and a part that is too long or short will not work correctly, leaving unwashed areas or touching body elements.
- Once a year
- Once every two years
- Only when it stopped working
- I don't know how often
⚠️ Attention! It is strictly forbidden to turn on the windshield wiper motor when the arm is removed or the blade is missing. This will lead to instant failure of the gearbox and a possible short circuit in the wiring.
It is also worth paying attention to the condition of the rubber seals under the cover. If they dry out, water can get inside the mechanism, causing corrosion. It is recommended to immediately replace them with new ones.
Sometimes owners forget to install a spring, which provides the pressing force of the brush to the glass. Without it, the rubber simply will not contact the surface, and cleaning will become impossible.
Selecting a Suitable Replacement
When choosing a new wiper for Nissan Note It is important to focus not only on the brand, but also on the type of fastening. There are several standards: hook, side pin and specific adapters for Japanese cars.
Original parts Nissan usually have a spare part number, which can be found in catalogs. They guarantee a perfect fit, but are more expensive than their analogues. Alternatives include quality brands such as Bosch, Denso or Valeo, offering universal kits.
| Brand | Mounting type | Service life | Price |
|---|---|---|---|
| Nissan Original | Specific | 2-3 years | High |
| Bosch Aerotwin | Universal | 1-2 years | Average |
| Denso | Adapted | 1.5-2 years | Average |
| Chinese analogues | Miscellaneous | 6-12 months | Low |
Pay attention to the availability of winter brush options if you live in a region with a harsh climate. They have a protective cover that prevents the frame from icing.
Before buying a new brush, measure the length with an old ruler - sometimes there may be tolerances at the factory, and the standard size will not fit perfectly.
Installation and performance check
After choosing and purchasing a new brush, proceed with installation. Place the lever on the motor shaft, making sure it is seated all the way and aligned with the splines. At this stage, it is important not to confuse the position of the lever relative to the glass.
Tighten the fastening nut by hand so as not to damage the thread, and then tighten it with a wrench. The force should be sufficient for fixation, but not excessive, so as not to deform the plastic.
Correct installation of the lever ensures uniform wear of the rubber and absence of vibrations when the wiper operates.
Replace the decorative cap, making sure that all clips snap into place. Now you can check the operation of the mechanism. Turn on the ignition and activate the rear windshield wiper.
Make sure that the brush does not jump off the glass and does not leave streaks. If you hear a noise or squeak, the shaft may not have been lubricated or the lever may not be set at the correct angle.
⚠️ Attention! If the wiper does not work after installation, check the fuse in the mounting block. On Nissan Note There is often a separate fuse for the rear wiper.
Diagnosis of mechanism problems
Sometimes the problem is not in the brush itself, but in the drive mechanism. If the wiper moves jerkily or stops mid-stroke, this may indicate wear on the gearbox gears or a weakened spring.
In such cases, simply replacing the rubber band will not help. It is necessary to disassemble the assembly completely and inspect the plastic gears. If the teeth are chipped or worn, the gearbox must be replaced.
It is also worth checking the wiring going to the motor. On hatchbacks, wires often break where they exit the body due to constant vibrations of the trunk door.
- 🔍 Inspect the gears of the gearbox for chips and cracks
- 🔌 Check the integrity of the wire insulation at the bend
- ⚙️ Lubricate the shafts and joints with silicone grease
If the problem is electrical, the motor assembly may need to be replaced. This is a more complex procedure that requires removing the trunk trim.
