The situation when the rear windshield wiper stopped working Nissan Note, occurs quite often among owners of this car. The problem can manifest itself in different ways: the brush simply does not move, works intermittently, or does not return to its original position after being turned on. For driving safety in rainy weather, the proper operation of the rear windshield wiper is critical because it provides visibility through the rear window.
Ignoring this malfunction may result in you not seeing obstacles or pedestrians behind the vehicle when maneuvering. Owners Nissan Note Often they are faced with the fact that the problem cannot be solved by simply replacing the rubber band or cleaning the glass. The reason often lies deeper - in the electrical circuit or the mechanical drive of the mechanism itself.
In this article we will examine in detail the main reasons for the failure of the rear wiper on models Nissan Note different generations. You will learn how to carry out diagnostics yourself, check fuses and gear motors, and also when to turn to professionals. We will look at both the electrical and mechanical aspects of the breakdown.
The main reasons for rear wiper failure
Before you disassemble the trunk door or reach into the fuse box, it is important to understand the nature of the problem. Most often, the problem lies in one of three components: electrical, mechanical or control unit. By car Nissan Note Wire connections are especially vulnerable due to constant vibration and kinks.
The most common cause is a broken wiring in the tailgate corrugation. Because the rear wiper is mounted on a sliding door, the bundle of wires constantly flexes as it opens and closes. Over time, the insulation cracks and the copper strands inside break. This leads to loss of contact, and wiper motor it just doesn't receive the command to start.
The second common reason is failure of the gear motor. There are gears inside the mechanism that can wear out or break over time, especially if the wiper was turned on when the glass was icing up. The armature winding of the motor may also burn out due to overload or short circuit. In this case, you may hear the relay click, but there will be no movement of the brush.

- ⚡ Burnt fuse or relay in the block
- ⚙️ Mechanical jamming of the wiper gearbox
- 💧 Oxidation of contacts in the motor connector
Diagnostics of electrical parts and fuses
The first step in troubleshooting should be to inspect the fuse box. On Nissan Note The operation of the rear windshield wiper is controlled by a separate fuse, which is located in the passenger compartment, usually under the dashboard on the driver's side or in the engine compartment. You need to find a fuse layout diagram, which is often pasted on the block cover.
If the fuse is good, the problem may be in the relay. On many versions Nissan Note The wipers are controlled through a relay, which can get stuck or lose contact. You can check it by replacing it with a known good one (for example, from a headlight washer or horn, if they have the same markings). It is also worth checking the condition motor connector, since moisture and dirt often lead to corrosion of the contacts.
For more accurate diagnostics, you will need a multimeter. It is necessary to remove the trunk door trim and test the circuit from the motor connector to the fuse box. If there is no voltage at the motor contacts when the ignition and wiper switch are on, then there is a break somewhere along the way. This often happens where the wire enters the rubber corrugation.
⚠️ Attention: Before starting any work on the electrical system, be sure to disconnect the negative terminal of the battery to avoid short circuit and damage to the electronic control unit.
Sometimes the problem is solved by cleaning the contacts. If you see green deposits or rust on the connector, they will need to be cleaned with fine sandpaper or contact cleaner. After cleaning, the contacts should be treated with a conductive lubricant to prevent further oxidation.

Mechanical diagnostics and gearbox testing
If the electrical part is working properly and voltage is supplied to the motor, but the wiper does not move, the problem lies in the mechanics. In this case, the motor may hum or make a characteristic sound, but the brush remains in place. This indicates a breakdown inside wiper gearbox. The plastic gears inside the housing wear out and break off over time.
It often happens that the mechanism jams due to dirt, sand or icing. If you tried to turn on the wiper on frozen glass, the gears could simply break under the load. In such cases, replacing the entire motor assembly is the most reliable solution, since disassembling the gearbox and replacing gears often does not provide long-term results.
To check the mechanics, you need to remove the wiper motor. On Nissan Note This often requires removing the inner trim of the tailgate. Unscrew the motor mounts and disconnect the rods. Try turning the motor shaft by hand (if possible) or powering it directly from the battery. If the shaft does not rotate, the motor must be replaced.
☑️ Mechanical check
Pay attention to the condition of the rods and levers. Sometimes the problem is not in the motor, but in the fact that the wiper arm is deformed or its mount has become loose. In this case, the motor runs, but the force is not transmitted to the brush. Check that the lever is securely attached to the gearbox output shaft.
⚠️ Attention: Do not try to turn on the wiper if there is ice or snow on the glass. This is guaranteed to lead to the motor burning out or the plastic gears of the gearbox breaking.
DIY windshield wiper motor replacement
If diagnostics show that the motor is faulty, it must be replaced. Replacement process Nissan Note requires caution, since the trunk door has a complex geometry and many plastic fasteners. You will need a set of screwdrivers, wrenches, a new motor and possibly a new connector.
Start by removing the inner door trim. Carefully pry up the plastic clips and remove the panel. Open access to the wiper mechanism. Disconnect the electrical connector from the motor. Then unscrew the nut holding the wiper arm to the shaft and remove the arm itself.
Next, you need to unscrew the three bolts securing the motor to the door body. Be careful not to drop the bolts inside the door. Remove the old motor and install the new one. It is important to correctly assemble the wiper arm, placing it in its original position so that it does not rest against the glass when parking.
How to set the wiper lever correctly
Before installing a new engine, you need to turn on the ignition and press the wiper button so that it is in the “park” position. Then turn off the power and install the lever on the shaft in the same position. This ensures that when turned off the wiper will return to its original position.
After installing the new motor, reassemble everything in reverse order. Before installing the trim, be sure to check the operation of the wiper. If everything works, you can close the door and enjoy a clean rear window. Don't forget to recycle your old motor and obsolete parts.
Before purchasing a new motor, be sure to check its part number with the markings on the old one. For different years of production Nissan Note Different motors with different connectors and mountings can be used.
Problem with contacts in the door corrugation
One of the most insidious problems on Nissan Note is a break in the wires in the rubber corrugation connecting the body and the trunk door. At this point the wires experience constant bending loads. Over time, the insulation breaks and the wires break. This causes the wiper to only work in a certain door position.
To test this hypothesis, you need to remove the corrugation and carefully inspect the wires. Often a break occurs inside the insulation, and outwardly the wire appears intact. Use a multimeter in continuity mode to check the integrity of each wire in the bundle. Pay special attention to the power and ground wires.
If you find a break, the wires need to be twisted and properly soldered, and then insulated with heat shrink. A simple twist will eventually come apart again due to vibration. It is best to replace the entire wiring harness if it is very worn, or run new wires parallel to the old ones.
| Component | Symptom of malfunction | Remedy |
|---|---|---|
| Fuse | The wiper does not respond to the switch | Replacing the fuse with a similar one |
| Geared motor | There is a clicking sound, but there is no movement | Replacing the motor assembly |
| Corrugated wiring | The wiper only works when the door is open | Repair or replacement of wires |
| Wiper lever | The motor hums, the brush does not move | Replacing a lever or gear |
⚠️ Attention: Repair of corrugated wiring must be carried out using high-quality materials. Poor contact can cause the insulation in the confined space of the door to heat up and even burn.
Checking the switch and control unit
Sometimes the problem lies not in the actuators, but in the switch itself on the steering column. The contacts inside the steering column switch may become oxidized or worn out. If you do not feel a clear click when you press the button or the wiper does not respond correctly, you should check the switch.
On modern versions Nissan Note The wipers can be controlled via the electronic body control module (BCM). If the unit receives an incorrect signal from the switch or cannot process the command, the wiper will not turn on. In this case, computer diagnostics are needed to read errors.
Checking the switch requires dismantling it. Remove the plastic cover of the steering column and disconnect the switch connector. Test the contacts with a multimeter while pressing the button. If there is no contact, the switch must be replaced or repaired.
If all electrical and mechanical tests fail, the problem may be with the body control module (BCM). In this case, professional diagnostics using specialized equipment is necessary.
Prevention and care of the windshield wiper system
To avoid repeated breakdowns, it is necessary to regularly carry out preventive maintenance. Clean the wiper mechanism from dirt and sand. Use special lubricants for rubber seals and hinges. Do not turn on the wiper if the glass is covered with ice or a thick layer of dirt.
Check the condition of the brushes periodically. Worn brushes create unnecessary resistance for the motor, which accelerates wear on the gearbox. Change the brushes at least once a year or when smudges appear on the glass. Also monitor the condition of the wiring in the corrugation, carefully bending it if necessary.
When parking the car for a long time in the cold season, unfasten the wiper arm from the glass or place it in a vertical position so that the rubber does not freeze. This will save engine life when you turn it on for the first time after winter. Regularly checking fuses will also help you spot the problem early.
- 🧹 Clean the mechanism from dirt and ice before winter
- 🧴 Lubricate hinges and seals with silicone grease
- 🔄 Change brushes annually or if cleaning quality deteriorates
- ❄️ Do not turn on the wiper on icy glass
Frequently asked questions (FAQ)
Why does my Nissan Note's rear wiper work but does not return to its original position?
This is a common problem associated with a malfunction of the contact group inside the gear motor. The motor has a special mechanism that turns off the power only when the brush reaches the lowest point. If this mechanism is broken, the wiper will stop at a random location. The solution is to replace the motor assembly.
Is it possible to repair a wiper motor if the gears are burnt out?
Theoretically, you can find a gear repair kit and replace them, but in practice this is often not economically feasible and unreliable. Plastic gears have a limited lifespan and may break again after repair. It is better to install a new gear motor.
How to find out which fuse controls the rear wiper on a Nissan Note?
The fuse location diagram is located on the inside of the fuse box cover. This is usually a fuse marked "RR WIPER" or similar. If you don't have a diagram, use your vehicle's owner's manual or online diagrams for your specific model year.
Why does the wiper work jerkily?
Jerking can be caused by several reasons: poor contact in the motor connector, worn brushes, jammed mechanism or low voltage in the on-board network. Start checking with the contacts and condition of the brushes, then check the voltage at the motor terminals.
How much does it cost to replace a rear wiper motor on a Nissan Note?
The cost depends on whether you choose an original spare part or an analogue. The original can cost 2-3 times more. Replacement work usually takes about 1-2 hours and does not require complex equipment, so the cost of repairs in the service will be moderate. On average, replacement takes from 1 to 2 hours of work by a technician.
