Replacing the window lift motor on a Nissan Almera Classic: instructions with photos and nuances

Window lifters in Nissan Almera Classic (body B10, 2006–2012) is one of the most vulnerable electrical components. Over time, the motor begins to jam, make a grinding noise, or stop working altogether, leaving the window in a half-open position. If you encounter this problem, do not rush to go to the service center: you can perform the replacement yourself in 1–2 hours, saving up to 5,000 rubles. In this article we will analyze causes of breakdowns, we will select original and similar spare parts, and also show step by step door disassembly process taking into account typical mistakes.

Feature Almera Classic — design of the window lift mechanism with cable drive, where the motor is integrated into the gearbox. This simplifies replacement (no need to disassemble the entire mechanism), but requires care when working with cables. We tested the process on cars with different mileage and found critical nuance: when installing a new motor, be sure to check the condition of the plastic cable guides - their wear accelerates repeated failure.

Signs of a faulty power window motor

The first “bells” about an imminent breakdown appear long before complete failure. If you notice at least one of these symptoms, prepare for a replacement:

• 🔊 Grinding or crunching noise when raising/lowering the glass - a signal about wear of the gearbox gears or motor bearings.
• ⚡ Slow work (glass moves jerkily) - often caused by oxidation of contacts or wear of electric motor brushes.
• 🚫 One glass failure when the others are working, the motor is almost always to blame (less often, a broken wire in the door corrugation).
• 🔄 The glass “sags” after closing the door - a sign of weakening of the cable or play in the gearbox.

On Almera Classic motors break down more often front doors - they experience a lot of stress. Rear window regulators fail less frequently, but are more difficult to replace due to limited access. Before purchasing a spare part, check which motor is installed in your car: before 2009 it was installed 28510-4M000, after - 28510-4M001 (they are interchangeable, but differ in the cable fastening).

⚠️ Attention: If the glass “falls” down when you press the button up, the problem may not be in the motor, but in broken cable or deformation of the guides. In this case, the entire window lift mechanism will need to be replaced.

Which motors are suitable for Nissan Almera Classic

Original spare parts from Nissan They are expensive (from 3,500 rubles per piece), but last longer than their analogues. However, there are proven substitutes that save up to 60% of the budget. The table below shows the best options with article numbers and average prices (for 2026):

Part type	Article	Manufacturer	Price, ₽	Notes
Original	28510-4M000	Nissan	3 500–4 200	For models up to 2009
Original	28510-4M001	Nissan	3 800–4 500	For models after 2009
Analogue	28510-4M000-AM	AMC	1 200–1 500	The quality is close to the original, 1 year warranty
Analogue	28510-4M000-KOYORAD	Koyorad	1 800–2 200	Improved brushes, service life up to 150 thousand km
Used	—	Showdown	800–1 200	Risk of buying a worn part

When choosing an analogue, pay attention to connector polarity — for some Chinese manufacturers it may differ. Also check the contents: the box should contain mounting bolts (M5×12 mm) and plastic gear (sometimes sold separately). If you buy a used motor, ask the seller to take a video of its operation - this way you will exclude hidden defects.

Tools and preparation for replacement

To work you will need:

• 🔧 Socket wrench set (10 mm, 12 mm) - for removing the door trim.
• ⚒️ Phillips screwdriver (PH2) - for mechanism screws.
• 🔨 Plastic spatulas - to avoid damaging the trim clips.
• 📏 Scotch tape or duct tape - to fix the glass in the raised position.
• 🔋 Multimeter — to check the power supply on the connector (optional).

Before starting work disconnect the negative terminal of the battery - this will prevent a short circuit if the wires accidentally touch. Also prepare your workplace:

Place the car on a flat surface|Open the window all the way and secure it with tape|Remove the negative terminal of the battery|Put a rag under the door (in case the bolts fall)|Prepare a container for small parts-->

If you are changing the motor for the first time, take a photo location of cables and fastenings before disassembling - this will help avoid errors during assembly. Pay special attention plastic trim clips: on Almera Classic they often break if removed carelessly. Buy spare parts in advance (item no. 90467-01200, ~50 ₽ per piece).

⚠️ Attention: Do not use metal screwdrivers to pry up the trim clips - they will scratch the plastic. If the clip breaks, do not try to glue it with superglue: vibrations will quickly destroy the connection.

Step-by-step instructions for replacing the motor

We start disassembling with removing door trim. On Almera Classic it is secured with 8 clips and 2 screws (under the handle and speaker). Carefully pry the lower edge of the trim at the threshold with a spatula and pull up - the clips should come out without effort. If the casing does not budge, check whether you forgot to unscrew the screws.

After removing the casing you will see window lift mechanism. It consists of:

1. Motor with gearbox (fastened with 3 bolts).
2. Cable in a plastic sheath.
3. Guide rollers (2 pieces).
4. Fastening the glass to the cable (plastic clamp).

To get to the motor:

1. Disconnect the power connector (press the latch and pull down).
2. Unscrew the 3 motor mounting bolts (10 mm socket wrench).
3. Carefully remove the motor from the groove without pulling the cable.

Installing a new motor is done in reverse order, but there is key nuance:

How to properly tension the cable?

Before fixing the motor with bolts, make sure that the cable is tensioned evenly, without sagging. To do this:

1. Install the motor into the groove, but do not tighten the bolts.

2. Manually rotate the gearbox clockwise to tighten the cable.

3. Secure the motor with bolts, holding the gear in a taut position.

If the cable sag, the glass will begin to “sag” after 1–2 weeks of operation.

After installation, check the operation of the mechanism before assembling the casing:

1. Connect the power connector.
2. Turn on the ignition and lower/raise the window 2-3 times.
3. Listen to the sound: grinding or jerking indicates improper cable tension.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when replacing a motor. Here are the most common:

• 🔧 Re-tightening of fastening bolts — leads to deformation of the gearbox housing. Tighten with a force of no more than 5 Nm.
• 🔌 Incorrect connector connection - if you reverse the polarity, the motor will work in the opposite direction. Check the circuit on the connector cover.
• 🧵 Ignoring cable wear - if the cable is frayed, its fibers will jam the new motor. Inspect the cable for abrasions.
• 🔊 Lack of lubrication — without treating the cable and guides, the service life of the motor is reduced by 30–40%.

Another common problem is loose fit of the casing after assembly. This happens due to:

• Broken clips (replace with new ones).
• Wires get caught between the trim and the door (place them in standard channels).
• Plastic deformation (heat with a hairdryer at 60°C and straighten).

Lubrication and prevention: how to extend the life of window regulators

To make the motor last longer, it is enough to carry out preventive maintenance once a year:

1. Cleaning the cable from dirt and old grease (use alcohol or carburetor cleaner).
2. Lubrication cables and guides with silicone spray (not lithol or grease - they thicken in the cold).
3. Checking fasteners glass - loose bolts create additional load on the motor.
4. Door tightness control — moisture ingress accelerates corrosion of the mechanism.

On Almera Classic especially vulnerable rear windows — their cables fray more often due to their smaller bending radius. For prevention, once every 2 years, remove the casing and inspect the condition of the cable. If you notice individual torn fibers, replace the entire cable (part no. 28530-4M000, ~1 200 ₽).

Also note window control unit (located in the driver's door). If there are signs of contact oxidation (flickering lights on buttons, spontaneous movement of glass), clean them with an eraser or a special spray Kontakt 60.

FAQ: Frequently asked questions about replacing the motor

Is it possible to replace the motor without removing the glass?

Yes, on Almera Classic it's possible. The glass must be secured in the raised position with tape, and then unscrew the motor without touching the guides. However, if the cable is very slack or torn, the glass will still have to be removed for tensioning.

Why does the new motor run slower than the old one?

This is normal - the new brushes in the motor have not yet gotten used to it. After 50–100 cycles, work returns to normal. If the speed is not restored, check the voltage at the connector (should be 12 V) and the condition of the cable.

What lubricant should I use for the cable?

The best option is silicone grease in spray (For example, CRC 2-26 or Wurth HHS-K). It does not thicken in the cold and does not attract dust. Litol or graphite lubricant are not suitable - they collect dirt and accelerate wear.

What should I do if the glass moves jerkily after replacement?

The reasons may be:

1. Incorrect cable tension (motor needs to be reinstalled).
2. Wear of plastic guides (replace, article number 28535-4M000).
3. Dirt gets into the gearbox (disassemble and clean).

Start by checking the cable tension - this is the most common reason.

How long does it take to replace?

If you have experience, 40–60 minutes per door. If you are doing this for the first time, allow 1.5–2 hours (including photographing the process and checking). Rear doors take longer to disassemble due to difficult access to the mechanism.
