Nissan Almera N16 windshield wiper trapezoid: how to choose, replace and repair

The windshield wiper trapezoid is one of those components Nissan Almera N16, which often goes unnoticed until it starts to act up. Meanwhile, not only the comfort of driving in the rain, but also safety depends on its serviceability: poorly functioning wipers can cause an accident due to limited visibility. Owners of Almeras with a mileage of 150+ thousand km know firsthand how a mechanism can suddenly jam or a brush can start to “walk” on the glass.

In this article we will look at everything you need to know about the windshield wiper trapezoid. Nissan Almera N16: from signs of wear And diagnostics to selection of spare parts (original vs analogues) and step-by-step replacement with your own hands. We will place special emphasis on common installation errors, which lead to premature failure of the unit. If your wipers start to slow down, squeak, or even fail, here you will find a solution.

Signs of a malfunctioning windshield wiper trapezoid

The first symptoms of problems with the trapezoid are often attributed to wear on the wiper blades or motor. However there is characteristic features, which directly indicate a malfunction of the mechanism:

• 🔧 Uneven brush movement - one “goes” faster than the other or remains in place while the second one works.
• 🔊 Grinding or knocking when turning on the wipers, especially at low speeds.
• 🛑 Jamming in one of the extreme positions (often after a long stay).
• 🌀 Spontaneous switching on wipers without command from the control lever.
• 💧 Poor glass cleaning due to brushes “slipping” over a dry area (the trapezoid does not provide uniform pressure).

On Almera N16 (especially with mileage) often occurs wear of plastic bushings trapezoids - they crumble over time, and the shaft begins to “play”. Another typical problem is corrosion of metal rodswhich blocks movement. If you ignore these symptoms, you can wait until the mechanism completely fails at the most inopportune moment (for example, during a rainstorm).

⚠️ Attention! If the wipers stop working at all, check the fuse first. F30 (10A) in the cabin and relay block K12 (on some versions Almera N16 it is responsible for the windshield wipers). Only after this disassemble the trapezoid.

Original articles and analogues of trapezoid for Almera N16

When choosing a trapezoidal wiper for Nissan Almera N16 It is important to take into account the year of manufacture and equipment. Supplies original parts Nissan under the articles:

Article	Description	Applicability	Average price, ₽
28550-4M000	Trapezoid assembly (full set)	Almera N16 2000–2006	8 500–12 000
28550-4M001	Trapezoid (modification for restyling)	Almera N16 2003–2006	9 000–13 000
28550-JM00A	Trapezius row (left/right)	All versions of N16	1 200–1 800
28555-4M000	Wiper motor	Compatible with trapeze 28550-4M000	4 500–6 500

Original trapezoids last longer (lifespan ~200 thousand km), but their high price forces many owners to consider analogues. Among the trusted manufacturers:

• 🔹 Febi (article 28550) - high-quality German analogues, resource ~150 thousand km. Price: 5,000–7,000 RUR.
• 🔹 Ruville (article 62301) - a budget option with acceptable quality. Price: 3,500–5,000 rubles.
• 🔹 Sasic (article 2805500) is a Korean brand, often found in stores. Price: 4,000–6,000 rubles.
• 🔹 Patron (article PT28550) - Russian manufacturer, suitable for economical repairs. Price: 2,500–4,000 RUR.

When choosing an analogue, pay attention to bushing material - cheap options often have plastic bushings (they wear out quickly), while the original and high-quality analogues use metal-ceramic or bronze bushings. Also check the package: some trapezoids are sold without rods or fasteners.

Trapezium diagnostics: how to determine the exact cause of the malfunction

Before changing the trapezoid, you need to make sure that this is the problem. Diagnostics includes several steps:

1. Checking the fuse and relay - as mentioned earlier, on Almera N16 The fuse controls the wipers F30 and relay K12 (located in the block under the steering wheel).
2. Motor test — with the wipers on, listen to whether the electric motor is working. If you hear a hum, but the brushes do not move, there is a mechanical problem.
3. Visual inspection — remove the plastic protection under the hood and check:
   • 🔧 Integrity of rods and levers.
   • 🔧 Backlash of the trapezoid shaft (if it “dangles”, the bushings are worn out).
   • 🔧 Traces of corrosion on metal elements.

Voltage check — if the motor does not show signs of life, check the voltage at its terminals (should be 12V when the ignition is on).

A common mistake in diagnosis is ignoring condition of the brush leads. On Almera N16 they are attached to the trapezoid through hinged joints, which become loose over time. If the leash “walks”, the brush will move asynchronously, creating the illusion of a broken trapezoid.

⚠️ Attention! If, when you turn on the wipers, you hear the sound of a motor running, but the blades do not move, do not keep the lever on for more than 10 seconds - this can lead to overheating and failure of the electric motor.

How to check a trapezoid without removing it?

Turn on the wipers at minimum speed and watch the blades move. If they stop in the same place (for example, in the middle of the glass), this is a sign of wear on the trapezoid gear teeth. If the brushes “jump” or move jerkily, the problem is in the bushings or rods.

Step-by-step replacement of the windshield wiper trapezoid on a Nissan Almera N16

Replacing the trapezoid with Almera N16 does not require special tools, but will require care - especially when working with plastic clips and brush leads. Average replacement time: 1.5–2 hours.

Step 1. Removing the wipers and plastic protection

Unscrew the nuts securing the brushes (the key is on 12 mm) and remove them from their leashes. Then remove the plastic protection under the hood - it is secured with 4-5 clips and 2 bolts (phillips screwdriver). Be careful: the clips are fragile, especially in the cold.

Step 2. Disconnecting the rods and motor

Unscrew the bolts securing the trapezoid to the body (the key is on 10 mm). Disconnect the rods from the leads - this may require squeezing the clamps with pliers. If the rods are stuck, treat the connection with a penetrating lubricant (for example, WD-40).

Step 3. Installing a new trapezoid

Transfer the brush leads to the new trapeze (if they are in good condition). Place the mechanism in place, secure with bolts and connect the rods. Important: Before final tightening, check the synchronization of the movement of the brushes by turning on the wipers for a short time.

Step 4: Setup and Testing

After installation, adjust the position of the brushes - they should be in the lower position (under the plastic casing) when turned off. If the brushes stop where they should, loosen the nut on the driver and adjust its position.

Repairing a trapezoid: when does it make sense to restore an old part?

It is not always necessary to replace the entire trapezoid; it can often be repaired by replacing worn elements. This is relevant if:

• 🔧 Worn only bushings (they can be replaced with bronze or metal-ceramic ones).
• 🔧 One damaged traction (sold separately).
• 🔧 Stuck gear due to corrosion (it can be cleaned and lubricated).

What you will need for repair:

• 🛠 Bushing repair kit (for example, 28550-VT000 for Nissan).
• 🛠 Lubrication Molykote G-N Plus or LIQUI MOLY LM47.
• 🛠 Set of screwdrivers and keys.
• 🛠 Drill with drill bit 8 mm (if the bushings are “stuck”).

Step by step repair:

1. Remove the trapezoid (as described in the previous section).
2. Disassemble it by removing the retaining rings and removing the rods.
3. Remove the old bushings - if they “fit” tightly, drill them out carefully without damaging the shaft.
4. Install new bushings, lubricating them before assembly.
5. Clean the gear and other metal parts from rust and lubricate.
6. Reassemble the trapezoid in reverse order.

Repair will cost 2–3 times less than buying a new trapezoid, but it only makes sense if minor wear. If the part body is cracked or the gear teeth are worn out, it is better to buy a new one.

Typical replacement mistakes and how to avoid them

Even experienced car owners sometimes make mistakes when working with a trapezoid. Nissan Almera N16. Here are the most common:

• 🚫 Re-tightening of fastening bolts — leads to deformation of the trapezoid body and jamming.
• 🚫 Ignoring lubrication — new bushings without lubrication wear out within 10–15 thousand km.
• 🚫 Incorrect installation of leashes - if they are mixed up, the brushes will move at odds.
• 🚫 Forgetting to check the fuse after replacement - if it burns out, the new trapezoid will not work either.
• 🚫 Use of incompatible analogues - trapezoids from Nissan Primera P12 similar in appearance, but not suitable for Almera N16.

Another common problem is incorrect adjustment of the final position of the brushes. If they do not stop under the plastic casing, but in the middle of the glass, this leads to:

• 🌧 Freezing of brushes in winter (due to moisture getting into the mechanism).
• 🔊 Increased wear of the motor (it continues to work, trying to “push” the brushes to the extreme position).

To avoid these problems, after installing the trapeze:

1. Turn on the wipers and wait until they complete a full cycle.
2. Turn off the ignition and manually move the brushes to the lower position (under the cover).
3. Tighten the nuts of the guides.

Tips for extending the life of your trapeze

To keep the windshield wiper trapezoid on Nissan Almera N16 lasted longer, follow these recommendations:

• 🌡 In winter in front of the parking lot turn off the wipers and lift the blades manually - this will prevent them from freezing to the glass.
• 🧴 Lubricate once a year trapezoid bushings (through grease nipples, if any, or by disassembling the mechanism).
• 🚿 Wash your windshield special shampoos - they reduce the load on the brushes and trapeze.
• 🔧 Check the play brush leads - if it appears, tighten the nuts or replace the hinges.
• 🔋 Monitor the on-board voltage — low voltage (less than 11.5V) increases the load on the wiper motor.

Pay special attention choice of windshield washer fluid. Cheap or diluted “anti-freeze” agents contain aggressive additives that corrode rubber trapezium seals and bushings. The best option is liquids based on isopropyl alcohol (for example, LIQUI MOLY Scheiben-Frostschutz).

⚠️ Attention! Do not use to lubricate trapezoids. Litol or Solid oil - they thicken in the cold and attract dirt. It is better to take specialized lubricants for plain bearings (for example, Molykote 3400A).

FAQ: Frequently asked questions about the Almera N16 windshield wiper trapezoid

Is it possible to drive if the trapeze creaks, but the wipers still work?

Short term - yes, but it's not worth the risk. A squeaking noise usually indicates worn bushings or lack of lubrication. If you ignore the problem, the trapezoid may jam at any time (for example, during rain), leaving you without visibility. We recommend lubricating the mechanism or replacing the bushings as soon as possible.

Will the trapezoid from Nissan Primera P12 fit Almera N16?

No, despite the external resemblance, these trapezoids not interchangeable. U Primera P12 different angle of attachment of rods and different length of leads. Installing such a trapezoid will lead to incorrect operation of the wipers or their jamming.

How often should the trapezoid be lubricated?

The optimal interval is once every 30–50 thousand km or once a year (before winter). If you often drive in the rain or wash your car with high pressure, lubricate the mechanism more often. Use lubricants based on molybdenum or graphite - they last longer and are not washed out by water.

Why do the wipers work jerkily after replacing the trapezoid?

There may be several reasons:

• 🔧 Insufficient lubrication of bushings.
• 🔧 Distortion during installation (check the fastening of the trapezoid to the body).
• 🔧 Motor malfunction (if it is worn out, it may not cope with the load).
• 🔧 Contamination of the trapezoid gear (needs to be cleaned and lubricated).

Disassemble the mechanism and check each element.

Is it possible to repair a trapezoid if it is cracked?

If the crack is on body trapezium - repair is pointless, since the part has lost its rigidity and will deform under load. If cracked traction, it can be replaced separately (article no. 28550-JM00A). In other cases, the trapezoid assembly will need to be replaced.
