Windshield cleaning system on a car Nissan Note is a critical safety element, especially in harsh Russian winters or heavy rains. Over time, the mechanism responsible for the movement of the brushes begins to wear out, which leads to a decrease in the efficiency of the wipers and the appearance of extraneous noise. The main part of this unit is the windshield wiper trapezoid, which transmits rotational motion from the electric motor to the wiper arms.
Ignoring signs of malfunction can cause the wipers to stop cleaning the glass completely, leaving dangerous vision areas. Model owners Nissan Note often encounter the problem of jamming or sagging of the mechanism, which requires immediate intervention. Understanding the structure of the unit and the ability to correctly diagnose it will save significant money on visits to the service center.
Design and principle of operation of the mechanism
The windshield wiper trapezoid is a complex system of levers and rods connected by hinges. Its main task is to convert the rotation of the electric motor shaft into reciprocating movements of the wiper arms. By car Nissan Note this design is designed taking into account the aerodynamics of the body, ensuring a tight fit of the blades to the curved glass.
The key element is the power rod, which connects the motor to the central axis. Wear of the hinge joints is inevitable during long-term use, since they are constantly exposed to moisture, reagents and dirt. This leads to an increase in gaps and the appearance of play, which you feel as a beating when the wipers operate.
It is important to understand that electric motor The windshield wiper has a built-in gearbox, which is also subject to wear. If the trapezoid is stuck, the motor may burn out trying to overcome the resistance. Therefore, timely replacement of worn components prevents more serious damage.
⚠️ Attention: If you hear a grinding or metallic knocking sound from under the hood when you turn on your wipers, turn them off immediately. Continued operation may destroy the plastic gears inside the motor.
Symptoms of a faulty trapezoid
Problems with the mechanism can be identified by a number of external signs that appear gradually. Most often, owners notice that the wipers move unevenly or stop in abnormal positions. On Nissan Note this is especially noticeable since glass has a large area and complex geometry.
One of the most striking symptoms is the appearance of play in the wiper arms when they dangle freely when the engine is turned off. Another characteristic feature is a change in the trajectory of movement: the brushes can come off the glass or, conversely, press too hard, which causes a squeak.
Sometimes the problem is disguised as a malfunction of the electric motor. If the mechanism jams, the motor may hum but not move. In such cases it is necessary to check lubrication of hinges and the condition of the rods before changing an expensive engine.

Diagnosis and problem identification
For an accurate diagnosis, it is necessary to remove the plastic elements of the decorative grille covering the mechanism. On Nissan Note This is usually a plastic trim under the windshield that is attached with clips. Gently unclip them to gain access to the trapezoid.
A visual inspection can reveal corrosion damage, cracks in plastic bushings or lack of lubrication. Try manually rocking the levers: if you feel significant play, it means the hinges are worn out. Also check the integrity of all rods for bends.
If no visual problems are found, but the wipers operate jerkily, there may be a problem in adjusting the angle of the arms. An incorrect angle of brush pressure creates excessive resistance that the motor cannot cope with. Use a torque wrench to check the torque of the driver nuts.
- Check status articulated bushings for play and dryness.
- Inspect the rods for mechanical damage or corrosion.
- Make sure there are no distortions in the places where it is attached to the body.
Selection of spare parts: original or analogue?
When selecting a new trapezoid for Nissan Note There are several options worth considering. The original part (OEM) provides a perfect fit, but often costs significantly more. Article numbers of original spare parts can be found in catalogs according to the VIN code of your car.
High-quality analogues from trusted brands can be an excellent replacement if they have good reviews. However, cheap Chinese copies are often made of soft plastic, which quickly deforms under load. The cheapness of such a part may result in the need for a repeat purchase in six months.
Pay attention to the package: some kits are sold together with an electric motor, while others are sold only as a mechanism. For Nissan Note It is often more profitable to buy a trapeze separately if the motor is in good condition. Check that all necessary fasteners and bushings are included in the kit.
⚠️ Attention: When purchasing an analogue, be sure to compare the number of attachment points and the length of the rods with your old part. Differences of even a few millimeters can make installation impossible.
Which analogue brands are considered the best?
The brands Denso, Bosch and Vaico have proven themselves well in the spare parts market for Nissan Note. They offer products with metal-ceramic bushings that last longer than standard plastic counterparts. Among the budget options, you can consider the products of the CTR company, but they require more careful quality control when purchasing.
Trapezoid replacement process
Replacing the mechanism requires care and a basic set of tools. First you need to dismantle the wiper arms by unscrewing the fastening nuts and removing them from the slots. Be careful not to scratch the glass.
Then the plastic trim under the windshield is removed. Disconnect the electric motor power connector and unscrew the bolts securing the trapezoid to the body. On Nissan Note Bolts often stick, so use a penetrating lubricant.
Install the new trapezoid in the reverse order. Pay special attention to alignment: Before final tightening the bolts, run the wipers one cycle to ensure they stop in the correct position. If they stop higher or lower, you will have to adjust the position of the leashes.
☑️ Preparing to replace the trapezoid
Before unscrewing the wiper arm nut, mark with a marker its current position relative to the slot. This will help you quickly return it to its place in the same corner after installing a new trapezoid.
Adjustment and final check
After installing a new part, it is critical to make adjustments. The wipers should stop at the lowest point without touching the glass frame or going too far up. Incorrect adjustment will cause the brushes to hit the rubber band or leave unwashed areas.
Check the operation of the mechanism in different modes: intermittent, low and high speed. Make sure that there are no extraneous sounds, vibrations and that the trajectory of movement is smooth. If the motor is overloaded, you may have installed the arms incorrectly.
Finally, check the tightness of all seals under the trim. Water entering the mechanism quickly washes away the lubricant and causes corrosion. Use a high-quality sealant to treat the areas where the plastic joins the body.
- Make sure the brushes don't touch glass frames in extreme positions.
- Check for vibration when running at high speed.
- Make sure the mechanism is quiet and runs smoothly.
Correct adjustment of the wiper arms after replacing the trapezoid is more important than replacing the part itself, since it is this that ensures clear visibility and durability of the mechanism.

Choosing the right part depends on the specific modification of your vehicle. Errors during selection can lead to the fact that the mechanism simply does not fit into its standard place. Always check the VIN when ordering parts.
Why is it important to replace the trapeze as a set?
It is recommended to change the trapezoid as a set, since the wear of the rods occurs evenly. If you only replace one side, uneven friction can cause the new part to fail quickly. In addition, the old levers may not fit the new trapezoid due to wear on the seats.
Frequently asked questions from owners
Is it possible to restore an old trapezoid rather than replace it?
In some cases, it is possible to restore the mechanism by replacing worn bushings and adding lubricant. However, if the rods are bent or there are cracks in the housing, restoration is not practical. Complete replacement more reliable and durable.
How often should the trapezoid be lubricated?
It is recommended to lubricate the hinges every 1-2 years, especially before the winter season. Use special silicone lubricants, which are not washed off with water and do not freeze in the cold.
What to do if after replacement the wipers hit the glass?
This means that the levers are installed incorrectly. It is necessary to loosen the nuts of the leads, align their position manually and tighten. Critical set the leads to the lowest point when the engine is turned off, but the shaft is in its original position.
Is it possible to replace the trapeze without removing the motor?
No, on Nissan Note the trapezoid is attached to the motor, and to dismantle it you need to unscrew the connection. Often you have to remove the motor itself to gain access to the mounts.
