Trapezoid wipers on Nissan Almera Classic B10 (2006–2012) - a unit that often fails after 100–150 thousand kilometers. Owners are faced with problems: from squeaks and jamming to complete failure of windshield wipers at the most inopportune moment. The reason usually lies in wear of plastic bushings, corrosion of metal parts, or burnout of the electric motor. But don’t rush to change the entire trapezoid - in 70% of cases it can be restored!

In this article we will analyze all aspects of working with trapezoidal wipers on Almera Classic B10: from fault diagnosis to step-by-step replacement. You will find out what Article numbers of original and analog parts fit perfectly, how to avoid mistakes during installation and why even a used trapezoid can last longer than a new one if it is properly prepared. The material is based on the experience of service technicians and reviews of owners with a mileage of 200 thousand km.

Signs of a faulty wiper trapezoid

The first symptoms of problems with the trapezius are often ignored, attributed to “temporary glitches.” But if you notice them in time, you can save on repairs. Please note:

  • 🔊 Creaking or knocking when the wipers are operating, this is a sign of wear on the gearbox bushings or bearings.
  • 🐢 Slow motion brushes, especially at maximum speed - a signal of problems with the motor or mechanical resistance.
  • 🛑 Stopping in any position - often the limit switch or an open circuit is to blame.
  • 💧 Incomplete contact of brushes to the glass - may indicate deformation of the trapezoid arms.
  • 🔥 Burning smell from under the hood - a critical sign of overheating of the electric motor.

If the wipers stuck in vertical position, do not try to force them back to their original state! This may damage the gearbox or burn a fuse. It is better to immediately turn off the power by removing the fuse F30 (15A) in the mounting block.

⚠️ Attention: On Almera Classic B10 The trapezium of the wipers is connected to the washer system. If after replacing the trapezoid the fluid supply stops working, check the integrity of the tubes - they are often touched during dismantling.

Articles and analogues: what to choose for replacement

Original trapezoid wipers for Nissan Almera Classic B10 has an article number 28550-4M000 (for models from 2006 to 2012). However, its price often exceeds 8–10 thousand rubles, which forces owners to look for alternatives. The table below shows proven analogues indicating the average cost and features:

Brand Article Price, ₽ Features
Nissan (original) 28550-4M000 8 500–10 000 1 year warranty, fully compatible
Febi 28550 4 200–5 000 High-quality bushings, but may require some modification to the mounts
Ruville 52113 3 800–4 500 A good budget option, but there are defective motors
Sasic 2855004M00 3 500–4 000 Suitable for Renault Logan first generation - complete interchangeability
Used (contract) — 1 500–3 000 There is a risk of buying a worn-out unit, but with proper inspection it will last 3–5 years

When choosing an analogue, pay attention to quality of plastic bushings - they must be from polyamide or fluoroplastic, and not made of cheap plastic. Also check the package contents: some kits are missing fasteners or rubber seals.

Diagnostics: how to determine that the trapezius is to blame

Before replacing the trapezoid, make sure that the problem is not in other elements of the system. Check using the algorithm:

  1. fuse: Check F30 (15A) in the mounting block. If it burns out, the reason may be a short circuit in the motor.
  2. Wiper relay: Located in the relay box under the steering wheel (relay K12). Swap it with a similar one (for example, with a horn relay) and check the operation.
  3. Steering column switch: Contacts often oxidize. Disassemble and clean them with alcohol.
  4. Electric motor: Remove the trapezoid and feed it directly to the motor 12V (red wire - "+", black - "-"). If it doesn't turn, that's the problem.
  5. Mechanical part: Manually check the stroke of the levers. If they move tightly, the bushings are worn out or the rods are bent.

If, after checking all the elements, the wipers still do not work, and the motor is humming, but the brushes are in place - Trapezoid is 100% to blame. Most often, the plastic gear of the gearbox breaks or the worm mechanism fails.

How to check the motor without removing the trapezoid?

Connect a voltmeter to the trapezoid connector (pins 1 and 2) and turn on the wipers. If there is voltage (12V), but the motor does not work, it has burned out. If there is no voltage, the problem is in the wiring or fuse.

Step-by-step replacement of trapezium wipers with Almera Classic B10

To replace the trapezoid you will need:

  • 🔧 Set of sockets and keys (10 mm, 12 mm)
  • 🔨 Flat and Phillips screwdrivers
  • 🧲 Magnet for bolts (so as not to be dropped into the engine compartment)
  • 🧴WD-40 or similar lubricant
  • 🔋 Multimeter (for checking wiring)

Average replacement time - 1.5–2 hours for beginners and 40–60 minutes for experienced craftsmen. Follow the instructions:

☑️ Preparing to replace the trapezoid

Done: 0 / 4
  1. Removing the plastic protection:

    Unscrew 4 plastic clips and 2 bolts 10 mm under the hood. Carefully remove the protective cover without damaging the latches.

  2. Electrical disconnection:

    Disconnect the trapezoid's power connector (it is secured with a plastic latch - press it with a screwdriver). Check contacts for oxidation.

  3. Dismantling the old trapezoid:

    Unscrew the 3 bolts securing the trapezoid to the body (12 mm). One of them is hidden under a rubber seal - don't lose it!

  4. Installing a new trapeze:

    Lubricate the bushings before installation lithol or graphite lubricant. Secure the trapezoid with bolts, but do not tighten them completely - first check the movement of the wipers.

  5. Adjusting the position of the brushes:

    Turn on the wipers and wait until they are in the down position. Only then tighten the bolts completely.

⚠️ Attention: On Almera Classic B10 If the trapezoid is installed incorrectly, the wipers may cling to the hood! Before final fixation, check the gap (must be at least 10 mm).
💡

If after replacement the wipers operate jerkily, lubricate the worm gear of the gearbox with silicone grease. This will eliminate squeaks and extend the life of the mechanism.

Trapezoid repair: when replacement is not necessary

In 60% of cases, the trapezoid can be repaired, saving 3–5 thousand rubles. Main problems and ways to solve them:

Malfunction Reason Repair
Creak when working Wear of plastic bushings Replacing bushings with bronze or fluoroplastic ones
Wipers stop in random position Reducer gear wear Replacing the gear (part number 28550-4M010)
Slow brush movement Oxidation of motor contacts Cleaning contacts, lubricating bearings
One brush doesn't work The lever is bent or the rod is broken Aligning the lever or replacing the rod

For repair you will need:

  • 🔧 Bushing repair kit (For example, Febi 28550)
  • 🧴 Bearing grease (LIQUI MOLY LM 47)
  • 🔨 Set of screwdrivers and pliers
  • 🧲 Epoxy glue (for fixing new bushings)

If the plastic gear of the gearbox is broken, it can be temporarily repaired using epoxy resin, but this solution will extend the life of the trapezoid by only 3–6 months. For long-term repairs, it is better to replace the gear with a new one.

Tuning and modernization of trapezium wipers

Standard trapezoid Almera Classic B10 is not reliable, but it can be improved:

  • 🔧 Replacing plastic bushings with bronze ones — increases resource by 3–4 times. Suitable bushings from VAZ 2110 (article 2110-3408020).
  • 💡 Installing a brushless motor from Toyota Corolla E12 — reduces the load on the gearbox and eliminates sparking.
  • 🛠️ Strengthening trapezoid arms — welding additional stiffeners prevents deformation.
  • 🌧️ Washer system upgrade — installing an additional pump increases the fluid pressure.

One of the most effective upgrades is replacing the standard motor with motor from Renault Megane 2 (article 7701207468). It is more powerful and durable, but it will require some modification of the fastenings.

⚠️ Attention: When installing non-standard motors, check compatibility with the gearbox! Some models have a different rotation speed, which may lead to overheating.
💡

Replacing plastic bushings with bronze ones is the easiest and most effective way to extend the life of your trapezoid. It takes 1–2 hours and costs 200–300 rubles.

Common replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to repeated repairs. Here are the most common:

  1. Improper installation of wipers:

    If the brushes are installed upside down, they will not adhere well to the glass. Check the marks on the levers - they should look up.

  2. Re-tightening of fastening bolts:

    This deforms the plastic body of the trapezoid. Tighten the bolts to torque 8–10 Nm.

  3. Ignoring lubrication:

    Without lubrication, new bushings will wear out within 10–15 thousand km. Use lithol or graphite lubricant.

  4. Untested operation of the limit switch:

    If the wipers do not stop in the down position, bend the contact plate of the switch.

Another common mistake is buying a trapezoid without checking the article number. On Almera Classic B10 There are two options for trapezoids:

- 28550-4M000 — for models up to 2010;

- 28550-4M001 — for models after 2010 (with modified motor mounting).
