Vehicle operation Nissan Almera Classic in a changing climate imposes serious obligations on the vehicle safety system. One of the key systems that provides visibility in bad weather is the windshield wiper drive. When it stops working wiper motor, the driver finds himself in a critical situation, especially during the rainy season or during snowfall. Ignoring the symptoms of a malfunction can lead to a complete shutdown of the unit and the need for expensive repairs.
Owners Almera Classic Often they encounter the fact that the mechanism freezes in an unnatural position or begins to make strange sounds before stopping completely. In most cases, the problem lies not in complex electronics, but in simple brush wear, jamming of the trapezoid, or burnout of the commutator itself. electric motor. Understanding the principles of operation of the mechanism allows you to independently diagnose and save money on a visit to the service center.
Diagnostics of windshield wiper drive malfunctions
The first step in detecting problems is to thoroughly check the electrical circuit and mechanical parts of the assembly. Drivers often mistakenly change motorwithout checking the status trapezoidal wiperswhich may be bent or clogged with dirt. If the travel levers do not move manually when the motor is off, the problem is definitely not electrical.
Carefully inspect the power connector and the fuse responsible for the operation of the system. For Nissan Almera Classic This is usually the fuse box in the engine compartment. If the fuse is intact, and when you turn on the mode you only hear a relay click or a quiet hum, but the levers do not move, it is most likely jammed gearbox or the armature winding has burned out.
Sometimes the reason lies in the oxidation of contacts inside the motor unit itself. Moisture entering through worn seals causes corrosion, which disrupts the contact of the brushes with the commutator. This leads to the fact that electric motor runs rough or refuses to start under load.
- 🔍 Check fuse F23 in the mounting block under the hood.
- 🔨 Try swinging the wiper arms with your hand when the ignition is off - they should move smoothly.
- ⚡ Inspect the connection chip for oxidation or melting of the plastic.
⚠️ Attention: Do not try to forcefully turn the gearbox gears with a screwdriver through the hole in the housing, as this may lead to the plastic teeth breaking off and the need to completely replace the unit.
Selection of original and analog spare parts
When purchasing a replacement, it is important to decide: original motor or use a high-quality analogue. Official part code for Nissan Almera Classic often changes depending on the year of manufacture and configuration, so always check the vehicle's VIN with the catalog number. The original spare part is guaranteed to last a long time, but costs much more.
There are many manufacturers on the market offering worthy replacements. Brands like Denso or Hitachi are often suppliers to the assembly line, so their products may be identical to the original. However, you should avoid cheap Chinese copies, since their service life often does not exceed one season.
It is critical to pay attention to the number of splines on the gearbox shaft and the shape of the housing. U Almera Classic they are specific, and installing the wrong one motor will result in the trapezoid simply not connecting to the shaft. Also check for a built-in parking sensor (limit switch) that returns the brushes to the down position after turning off.

Preparing tools and work area
Before starting work, you need to prepare a set of tools so as not to be distracted by searching for them during the dismantling process. For replacement wiper motor you will need standard keys, but there is a caveat: fastening can be done with specific bolts or nuts. It's best to have a set of 8mm to 14mm sockets on hand.
You will also need a Phillips screwdriver to remove the plastic decorative trims and possibly a flathead screwdriver to pry up the latches. Don't forget about contact cleaning fluid and shaft spline lubricant. It is more convenient to carry out the work on a level area, preferably with access to the lower part of the car, if you need to remove the protection.
Provide good lighting as all operations are carried out in the engine compartment where there are many shadows. If you are planning to change motor in the garage, prepare a portable lamp. Cleanliness of the work area is also important: small bolts and washers tend to fall into hard-to-reach places.
☑️ Preparing to replace the motor
⚠️ Attention: Be sure to disconnect the negative terminal of the battery before starting work to avoid short circuit when disconnecting the motor electrical connector.
Step-by-step instructions for dismantling and installation
The replacement process begins with dismantling the external elements. Remove the windshield wiper arms by unscrewing the fastening nuts under the plastic caps. This will provide access to the plastic grille under the windshield. Remove the grille by snapping the latches and you will see the mechanism trapezoids and myself motor.
Next, you need to disconnect the electrical connector from the housing motor. Be careful not to break the connector lock. After this, unscrew the bolts securing the engine itself to the body or to the trapezoid. Usually there are three. Carefully remove the motor, being careful not to damage the plastic gears of the gearbox.
Before installing a new part, check the condition of the splines on the shaft. If they were worn out on the old motor, parts of the trapezoid may also need to be replaced. Install new motor, tighten the mounting bolts with moderate force to avoid stripping the threads in the aluminum housing. Connect the connector and temporarily turn on the ignition to check.
What to do if the motor shaft does not turn?
If the new motor does not turn over immediately after connection, check whether it is mechanically blocked. Sometimes the shaft may jam during transportation. Try gently rocking the trapeze lever with your hand to unlock the mechanism.
After successful testing, reassemble the assembly in reverse order. Install the plastic grille, secure the wiper arms and put on the decorative caps. Be sure to set the arms in the correct position so that they are parallel to the body pillars.
- 🔧 Use a torque wrench to tighten the motor mounting bolts (torque 8-10 Nm).
- 🛠️ Apply a little lithol to the shaft splines before installation for smooth running.
- ⚙️ Check operation in the “Interval”, “Continuous” and “Washer” modes.
If the wipers do not return to the down position after installation, check the “parking point” setting on the new motor housing or adjust the position of the arms manually while the mode is on.
Typical repair mistakes and their consequences
One of the most common mistakes is ignoring the state trapezoids when replacing the motor. If the mechanism is clogged with dirt or has play, a new motor will quickly burn out as it will work under increased load. Always clean the trapezoid and lubricate the hinges before installing a new part.
Another mistake is incorrect installation of the levers. If you don't calibrate their position, the wipers will hit the glass or stop in the middle of your field of view. This is not only annoying, but also dangerous for driving safety. Make sure that the brushes lie straight down when the ignition is off.
Also, do not neglect checking the fuses. Sometimes replacing the motor does not help because the problem is in the relay or wiring. If new motor does not work immediately after installation, check the voltage at the connector using a multimeter.
⚠️ Attention: Do not use WD-40 to lubricate the gears of the motor gearbox, as it washes out the factory thick lubricant and leads to rapid wear of the plastic.
Proper preparation of the trapezoid and lubrication of the hinges increases the service life of the new motor by 2-3 times compared to a simple replacement without maintenance.
