Nissan Note Trapezium and Windshield Wipers: Complete Replacement and Repair Guide

There are several proven brands that have established themselves as reliable suppliers for Japanese cars. Original from Nissan always ideal in geometry, but expensive. An alternative is brands specializing in the Asian market, which take into account the specific shape of the windshield.

• 📏 Always measure old brushes with a ruler before purchasing, especially if the car has been repaired.
• ❄️ For the winter period, it is better to choose hybrid or frameless brushes with a protective cover.
• 💰 Original spare parts cost 2-3 times more than analogues, but last longer.

Diagnostics and repair of windshield wiper trapezoid

If the wipers begin to jerk, squeak, or leave opaque stripes, the problem may not be in the rubber band, but in the wiper itself. trapezoidal wiper. This is a mechanical unit that converts engine rotation into reciprocating movements of levers. Over time, the bushings wear out, play develops, and the lubricant dries out or turns into sticky dirt.

The first diagnostic step is a visual inspection and checking for play. You need to remove the plastic covers under the wipers and swing the arms. If there is a noticeable gap at the joints, trapezoid requires replacement or major repairs. Owners often try to lubricate the mechanism, but if the wear of the bushings is critical, lubrication will only temporarily solve the squeaking problem.

Replacing a trapezoid is not the most complicated procedure, but it requires care. It is necessary to dismantle the wiper arms, unscrew the plastic caps, remove the decorative trim (which often snaps into place and can crack if removed carelessly) and unscrew the bolts securing the mechanism to the body. It is important to remember to unplug the power connector electric motor before starting work.

When replacing a trapezoid, it is recommended to immediately replace the bearings or bushings, if they come separately. In some cases, it is easier to buy a new assembly, since the cost of repairs, taking into account time and lubrication, can be comparable to the cost of a new part. Use special silicone grease for plastic and metal, which is not washed off with water.

• 🛠️ Removing levers often requires a special puller or heating with a hairdryer to loosen stuck nuts.
• 🧼 Before installing a new trapeze, be sure to clean the seat from old dirt and rust.
• 🔩 The tightening torque of the bolts securing the trapezoid to the body must be accurate to avoid vibrations.

⚠️ Attention: When dismantling the wiper arms, do not use a pry bar or powerful arms without glass protection! One wrong move can lead to a crack in the windshield, the repair of which will cost several times more than a new trapezoid.

Step-by-step instructions for replacing brushes and levers

Replacing brushes with Nissan Note It seems like a simple task, but there are some nuances here. The wiper arms are attached to the engine shaft splines through a nut under a plastic cap. If you simply pull the brush upward, you may accidentally shift the position of the arm relative to the shaft, causing an incorrect fit angle in the future.

First you need to move the wipers to the “service position”. To do this, turn on the ignition, start the wipers and turn off the ignition while they are in a vertical position. Now you can carefully remove the plastic cap, unscrew the nut and remove the lever. Be careful: the lever spring is very powerful and can hit the glass hard if released suddenly. Place a towel or soft cloth under the lever.

The process of replacing the brush depends on the type of attachment. On Nissan Note The most commonly used system is “hook” or “pin” (pin). Press the lock and slide the brush along the lever. Install the new brush until it clicks. After installation, be sure to check the angle of contact and make sure that the brush does not touch the glass frame in its extreme positions.

Порядок действий:
1. Поднимите рычаг перпендикулярно стеклу.
2. Нажмите на фиксатор и сдвиньте щетку вниз по направлению к рычагу.
3. Снимите старую щетку.
4. Установите новую, убедившись в надежном защелкивании.
5. Верните рычаг на стекло, контролируя падение.

If you are replacing the entire lever, make sure that the new element has the same geometric parameters. Sometimes, after replacing the lever, it needs to be adjusted so that it stops in the right place on the glass. This is done by repositioning the retaining ring on the motor shaft, which requires disassembling the mechanism.

Elimination of creaking and vibration during operation

The creaking of the windshield wipers is not just an unpleasant sound, it signals that the rubber does not glide well on the glass or the trapezoid is overloaded. The main cause of squeaking is contamination of the glass or the rubber itself. A thin film of oil, road dust and exhaust products accumulates on the windshield, which ordinary water does not wash off.

Before changing the trapeze or buying new brushes, try to thoroughly clean the glass and the rubber bands themselves. Use a special glass cleaner or a solution of vinegar and water. Wipe the brush rubbers with a damp cloth to remove any adhered dirt. Sometimes lightly sanding the edges of the rubber with fine-grained sandpaper helps if it becomes burred.

If cleaning does not help, check the angle of the brush. On Nissan Note Due to the curvature of the glass, bending the lever is sometimes required. This must be done extremely carefully, using pliers with soft jaws. If the arm is not bent correctly, the brush will operate at an "angle" causing vibration and squeaking. Also check if the lever itself is twisted on the shaft.

• 🧽 Use glass degreaser before installing new brushes.
• 🌡️ In hot weather, rubber can “float”, so use silicone grease for seals.
• 🚫 Do not use car shampoos to wash your windshield - they leave a greasy film.

⚠️ Attention: If the squeak is accompanied by a characteristic knock, stop using the wipers immediately. This is a sign that the mechanism trapezoids is destroyed, and further operation will result in the engine jamming or breaking the levers.

Frequent breakdowns and how to fix them

In addition to the wear and tear on the rubber bands and trapeze, owners Nissan Note encounter electrical problems. A common malfunction is a blown fuse or failure of the wiper relay. If the wipers don't work at all, check the interior fuse box. This is usually a fuse labeled "WIPER" or "FR WIPER".

Another problem is the “floating” operating speed. The wipers may work slower than usual or intermittently. This is often due to wear on the commutator. wiper motor or poor contact in the connectors. Moisture entering the engine compartment causes corrosion of the contacts, which leads to unstable operation.

Sometimes the plastic gear in the motor gearbox breaks. This happens if the windshield wipers are turned on when they are covered in ice or snow. In this case, the motor hums, but the levers do not move. It is necessary to disassemble the motor and replace the plastic gear with a metal one (if possible) or completely replace the motor assembly.

It is also worth mentioning the problem with the rain sensor if it is installed in your configuration. If the sensor does not work correctly, the wipers may turn on randomly or not respond to drops. In this case, it is necessary to check the calibration of the sensor or replace it.

• 🔌 Check the connectors for oxides and moisture whenever possible.
• 🔋 A weak battery can reduce the torque of the wiper motor, making them sluggish.
• 🧊 Never turn on the wipers if the glass is covered with ice - this is a sure way to burn out the motor.
