Why the rear wiper does not work on a Nissan Juke: 7 reasons and how to fix the problem

Rear wiper on Nissan Juke - a small but critical element, especially in rainy weather or winter, when visibility through the rear window deteriorates sharply. If it stops working, this is not just an inconvenience, but a potential safety hazard: according to traffic police statistics, up to 12% of road accidents in the autumn-winter period occur due to limited visibility. Owners Juke (especially models F15 2010–2019) often encounter this problem, but in 80% of cases it can be fixed independently without contacting service.

In this article we will look at all possible reasons - from a banal fuse blown to wear of the gears of the motor gearbox, and we will also give step by step instructions with photos and diagrams for diagnostics and repair. We will pay special attention unique feature Juke: The rear wiper here is controlled through the same unit as the washer, so failure of one often affects the other. If you notice that the wiper not only does not move, but also does not make a characteristic buzz when turned on, this is a key sign for narrowing down the search for the problem.

1. Checking the fuse and relay: where to start diagnosing

The first thing to do is check fuse F30 (10A) in the mounting block. He is responsible for the rear wiper and washer circuit. On Nissan Juke The fuse box is located to the left of the steering wheel, under the cover with the inscription FUSE. Open it and find the fuse marked F30 (on some versions - F28, check the diagram on the back of the cover).

How to check a fuse without a tester? Visually: if the thread inside is torn or melted, it has burned out. But even if outwardly he is intact, be sure to replace it with a new one (cost - from 50 rubles). The fact is that microcracks in the thread may not be visible, but the fuse does not conduct current. Also check relay K11 (it is responsible for controlling the wiper) - its contacts could have oxidized. To do this:

• 🔧 Remove the relay (it is usually located next to fuse F30).
• 🔍 Inspect the contacts for the presence of green plaque or blackening.
• 🔄 Swap places with a similar relay (for example, from heated seats) and check if the wiper works.

If the wiper still does not work after replacing the fuse and relay, continue to the next step. But remember: never install a fuse of a higher rating - this can lead to a fire in the wiring!

2. Diagnostics of the wiper motor: how to check without removal

Rear wiper motor (drive) Juke located under the plastic trim in the rear door. Before removing it, you can preliminary check:

1. Turn the ignition on and activate the rear wiper using the steering wheel switch.
2. Listen: if you can hear buzzing or clicking noise, but the wiper does not move - the problem is in the mechanical part (gears, lever).
3. If complete silence — most likely, the motor itself is faulty or there is no power.

For accurate diagnosis you will need a multimeter. Connect it in voltage measurement mode to the motor contacts (they are usually marked as +12V And GND). When the wiper is on, the voltage should be 12–14 V. If there is voltage, but the motor does not work, it has burned out. If there is no voltage, the problem is in the wiring or control unit.

3. Wiring problems: where to look for an open or short circuit

Rear wiper wiring Juke passes through the corrugation between the body and the rear door. Due to constant opening/closing of the door, the wires may fray or break. To check them:

1. Remove the plastic trim on the rear door sill (it is secured with clips).
2. Locate the wiring harness in the corrugation and inspect it for cuts, melting or oxidation.
3. Test the wires with a multimeter:
   • 🔌 Red wire — positive from the fuse (should show 12V when the wiper is on).
   • 🔌 Black wire — ground (should show 0 Ohm when connected to the body).
   • 🔌 Yellow/green wire — signal from the control unit (should change the voltage when switching wiper modes).

If you find a break, do not twist the wires - this is a temporary solution. It is better to solder the connection and insulate it with heat shrink. Also check connectors on the motor and control unit - they could have oxidized from moisture (especially if the car is often parked in the rain).

⚠️ Attention: If you find melted insulation when checking the wiring, do not turn on the wiper until the problem is fixed - this can lead to a short circuit and failure of the control unit!

4. Faulty lever or gears: mechanical failure

If the motor hums, but the wiper does not move, the problem lies in the mechanical part. On Nissan Juke Most often they fail:

• 🔧 Reducer gear - a plastic part that wears out or breaks over time.
• 🔗 Traction (lever)connecting the motor to the wiper axis may bend or break.
• 🛠️ Wiper axle - if it is jammed due to corrosion or dirt.

To get to the mechanism you need:

1. Remove the plastic trim in the rear door (snap off the clips with a screwdriver).
2. Unscrew the 3 motor mounting bolts (usually a Phillips screwdriver).
3. Remove the motor along with the gearbox and inspect the gears.

If the gear is broken, it can be replaced separately (part number for Juke — 28550-JM00A, price ~800 rubles). If the problem is in the lever, it can also be purchased separately (article number 28551-JM00A). But it is often easier to replace the motor assembly (the original is 28550-4M000, ~3500 rubles; analogue from Febi — ~2000 rubles).

5. Problems with the control unit or switch

If the fuse, motor and wiring are ok, but the wiper still does not work, the problem may be:

• 🎛️ Body Control Module (BCM) — he is responsible for signals to the janitor.
• 🔄 Steering column switch — the contacts may have oxidized or worn out.
• 📶 Wiring from switch to BCM - open circuit or short circuit.

To check:

1. Remove the lower part of the steering column (unscrew the 2 T20 Torx bolts).
2. Disconnect the steering column switch connector and check the contacts for pin 5 (rear wiper signal).
3. If the contacts are clean, but there is no signal, the problem is in the switch (replacement ~1500 rubles).
4. If there is a signal, but does not reach the BCM, check the wiring (often frays under the driver's side mat).

Resetting BCM errors can sometimes help restore functionality. To do this:

1. Отключите минусовую клемму аккумулятора на 10 минут.
2. Подключите обратно и включите зажигание (не запуская двигатель).
3. 3 раза подряд включите/выключите задний дворник.
4. Заглушите машину и снова отключите клемму на 1 минуту.

If after this the wiper started working, the problem was a BCM firmware failure. If not, diagnostics with a scanner will be required (for example, Launch X431).

6. The rear wiper works, but does not synchronize with the washer

Unique Feature Nissan Juke — the rear wiper and washer are controlled through one unit, so their malfunctions are often related. If the janitor:

• 💦 Doesn't turn on when the washer is activated - check washer nozzle (it could get clogged) and fluid supply tube (may be pinched).
• 🔄 Works chaotically (turns on by itself) - guilty rain sensor (if installed) or BCM.
• ⚡ Jerks when the washer operates - the problem is time relay (it is responsible for synchronization).

To check synchronization:

1. Turn on the rear window washer.
2. The janitor must do 3–4 swings after spraying the liquid. If less, the problem is in the BCM settings.
3. If the wiper does not respond to the washer at all, check wire from washer pump to BCM (the contact often comes off).

To reset sync settings:

1. Включите зажигание.
2. Нажмите и удерживайте кнопку омывателя заднего стекла 10 секунд.
3. Отпустите и выключите зажигание.
4. Повторите 3 раза.

7. Replacing the rear wiper on a Nissan Juke: step-by-step instructions

If diagnostics show that the motor or mechanism is faulty, they will have to be replaced. For this you will need:

• 🔧 Phillips screwdriver and Torx T20.
• 🔨 Plastic remover for clips.
• 🛠️ New motor (item 28550-4M000) or gear (28550-JM00A).

Step by step replacement:

1. Remove the negative battery terminal (required!)
2. Open the back door and remove the plastic trim (carefully pry the clips with a puller).
3. Unscrew the 3 motor mounting bolts (they may be under plastic plugs).
4. Disconnect the power connector and remove the motor.
5. If you are only changing the gear, disassemble the gearbox (it is secured with 2 screws).
6. Install the new part and reassemble everything in reverse order.
7. Before installing the cover, check the operation of the wiper!

After replacement it may be necessary calibration wiper (if he started hitting the edges of the glass). To do this:

1. Включите зажигание.
2. Нажмите и удерживайте кнопку заднего дворника 5 секунд.
3. Дворник автоматически перейдёт в крайнее положение.
4. Отпустите кнопку и выключите зажигание.

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

This means that the gearbox gear is not fully engaged with the axle. Remove the motor and check the alignment of the teeth. Debris may also have gotten into the mechanism - blow it out with compressed air.

FAQ: Frequently asked questions about the Nissan Juke rear wiper

The wiper works, but very slowly. What is the reason?

Most likely worn out reducer gears or the lubricant has thickened in the mechanism. Try removing the motor, cleaning the old grease and applying new one (for example, LIQUI MOLY Silicon-Fett). If that doesn't help, the gears need to be replaced.

Is it possible to repair a burnt out motor or just replace it?

In 90% of cases, the motor cannot be repaired - its body is sealed and it is impossible to disassemble it without damage. An exception is if it burned only winding (can be rewound), but it's more expensive than buying a new one. The best option is to replace the motor assembly or a separate gearbox with gears.

After washing the rear wiper stopped working. What to do?

Probably water got into the motor connector or the contacts have oxidized. Remove the door trim, disconnect the connector and dry it with a hairdryer (without overheating!). Process contacts WD-40 or Contact breaker. If that doesn't help, check fuse F30.

The wiper only works in one direction. Why?

This is a sign breakage of the reverse gear of the gearbox or wear on motor brushes. Disassemble the mechanism and inspect the gears for chips. If the brushes are worn out (their length must be at least 5 mm), the motor must be replaced.

Is it possible to drive without a rear wiper?

Technically yes, but this violation of traffic rules (clause 4.8 of the List of faults), for which you can get a fine of 500 rubles. Moreover, in rain or snow it is significantly impairs visibility and increases the risk of accidents. If the wiper is broken, temporarily use washer by hand (spray the liquid and wipe the glass with a cloth).
