How to Properly Lift and Adjust Wiper Blades on a Nissan Juke

Wiper blades on Nissan Juke - it would seem like a trifle, but their incorrect operation can cause a lot of inconvenience: from stains on the windshield to complete failure at a critical moment. Owners of this crossover often encounter problems when the brushes “hang” in the lower position, do not rise all the way, or move jerkily. In 80% of cases, the culprit is misaligned mechanism settings or wear of drive parts.

In this article we will look at all possible reasonswhy are the brushes on Juke (including restyled versions F15 And J10) may not rise, and we will also give step by step instructions on their adjustment - from the simplest manual adjustment to disassembling the drive mechanism. We will pay special attention unique feature Nissan Juke: synchronization of brushes with a rain sensor, which often goes wrong after replacing the battery or updating the control unit.

Reasons why brushes do not rise on Nissan Juke

Before you reach for the tools, it's important to diagnose the root of the problem. On Juke Typical faults are divided into mechanical And electric. Mechanical ones usually manifest themselves as a gradual deterioration in performance (for example, the brushes begin to “sag” after each switch-on), and electrical ones - with a sudden failure or chaotic behavior.

Here are the key “symptoms” and their possible causes:

• 🔧 The brushes stop in any position — wear of the motor gearbox or a break in the wire in the corrugation between the body and the hood.
• ⚡ Moves jerkily or with a delay - oxidation of contacts in the fuse box (fuse F37 at 10A) or relay malfunction K3.
• 🔄 Doesn't return to original position — the calibration of the position sensor is broken (typical for cars after replacing the battery).
• 💧 Only work at one speed — failure of the resistor in the switch under the steering wheel or damage to the tracks on the control unit board.

On Nissan Juke 2010–2014 model years (before restyling) is often found plastic leash defect, connecting the motor to the trapezoid. It cracks over time, and the brushes begin to “walk” on the glass. On models after 2015 the problem usually lies in electronics - especially if the car is equipped with a rain sensor (RAIN SENSOR).

⚠️ Attention: If the brushes suddenly stop rising after washing or rain, first check drainage holes under the windshield. A system clogged with dirt can cause water to enter the motor unit, causing a short circuit.

Tools and preparation for work

To adjust or repair brushes on Juke you will need a minimum set of tools. Most operations can be performed without a hole or lift - just open the hood and remove the plastic protection under the glass.

List of what you need:

• 🔩 10 mm socket wrench - for unscrewing the trapezoid fastenings.
• ⚡ Multimeter - to check the voltage on the motor (should be 12–14 V with the ignition on).
• 🔧 Flat head screwdriver — for removing the plastic protection clips.
• 🧴 WD-40 or silicone grease — for processing gears and drivers.
• 📐 Ruler or template — to align the brushes according to the factory marks (the distance between the lower points should be 580–600 mm).

Before starting work necessarily:

1. Disconnect the negative terminal of the battery (at Juke it is located under the plastic cover in the trunk).
2. Install the brushes in service position: Turn on the ignition, press the wiper button to position OFF, then hold the lever up for 5 seconds until the brushes are vertical.
3. Take a photo of the original position of the mechanism - this will help avoid errors during assembly.

Step-by-step instructions: how to lift brushes manually

If the brushes stuck in down position and do not respond to the switch, first try to lift them mechanically. This method works if the problem is a broken motor synchronization or a jammed leash.

Algorithm of actions:

1. Remove the plastic plugs from the brush mounts (pry them off with a flat blade screwdriver).
2. Loosen the nuts fastening the brushes with a key on 13 mm (do not unscrew completely!).
3. Lift the brushes by hand to a vertical position and secure them to the glass with masking tape.
4. Turn on the ignition and activate the windshield wipers for 1–2 cycles. If the brushes return to their normal position, the problem is solved.

If after this procedure the brushes “sag” again, then it is necessary to trapezoid adjustment or replacing leashes. On Nissan Juke with rain sensor after manual adjustment may be required error reset via a diagnostic scanner (for example, ELM327 with the program Nissan DataScan).

⚠️ Attention: Never use excessive force when lifting brushes by hand! On Juke Plastic trapezoid gears are fragile and can be easily broken if overused. If the brush does not budge, first check to see if the motor is jammed (try turning it by hand after removing the trapezoid).

Adjusting the windshield wiper trapezoid

If manual adjustment does not help, you will have to adjust trapezoid - a mechanism that transmits movement from the motor to the brushes. On Nissan Juke it is attached to the body with three bolts and has two adjusting nuts for adjusting the position of the brushes.

Work order:

1. Remove the trapeze:
   • Unscrew the fastening bolts (torx T30).
   • Disconnect the motor connector (the white plastic clip must be lifted up).
   • Carefully pull the mechanism out through the opening under the glass.
2. Check the condition of the parts:
   • Inspect the plastic leashes for cracks.
   • Make sure the motor gear is not chipped.
   • Lubricate all rubbing parts with silicone grease.
3. Adjust the position of the brushes:
   • Loosen the nuts securing the leads to the shafts.
   • Install the brushes so that in the lower position they are on 10–15 mm below the hood line.
   • Tighten the nuts and check the movement of the brushes by turning on the motor directly from the battery (red wire - +12V, black - mass).

After assembly be sure to calibrate:

1. Turn on the ignition.
2. Press the windshield wiper lever to position INT (intermittent mode) and hold for 10 seconds.
3. The brushes should make a full cycle and return to their original position.

Problem	Probable Cause	Remedy
The brushes do not rise above the middle of the glass	The leash is worn out or the trapezoid adjustment is knocked down	Replacing the driver or adjusting the position of the nuts
Brushes move asynchronously	The attachment of one of the brushes to the shaft is loose	Tighten the fastening nut, check the splines
Brushes only operate at high speed	The resistor in the switch or control unit is faulty	Switch replacement or unit repair
Brushes get stuck after washing	Water getting into the motor or contact oxidation	Dry the motor, clean the contacts

Replacing the windshield wiper motor

If diagnostics show that the problem is motor (there is no voltage at the output, the gear rotates manually with jamming), it will have to be replaced. On Nissan Juke Two types of motors are installed:

• 28510-4M000 — for cars without a rain sensor;
• 28510-4M010 - for versions with RAIN SENSOR.

Replacement process:

1. Remove the trapezoid (as described in the previous section).
2. Unscrew the three bolts securing the motor to the trapezoid (torx T20).
3. Disconnect the connector and install a new motor. Attention: on models with a rain sensor, the connector has an additional wire (usually blue) - do not confuse it when connecting!
4. Reassemble the mechanism in reverse order and perform calibration.

The cost of a new motor is from 3,500 to 6,000 rubles depending on the configuration. When purchasing used parts, be sure to check gear condition and integrity of the ground wire (at Juke it often rubs against the body).

What to do if the new motor does not work?

If after replacement the motor shows no signs of life, check:

1. Availability 12V on the red wire of the connector when the ignition is on.

2. Fuse integrity F37 (10A) in the block under the steering wheel.

3. Relay status K3 — it is responsible for supplying power to the motor. Try replacing it with a known good one (for example, with a heated glass relay).

4. If there is power, but the motor does not spin, there may be a winding defect. In this case, the part must be replaced under warranty.

Nuances for Nissan Juke with rain sensor

Models Nissan Juke in top trim levels (Tekna, Nismo) are equipped rain sensor, which is integrated into the windshield wiper system. This sensor not only automatically turns on the brushes, but also controls their position via the body control unit (BCM).

If, after replacing the battery, flashing the firmware, or turning off the power, the brushes begin to behave unpredictably (for example, they stop at the top or work intermittently), follow these steps:

1. Reset BCM errors:
   • Connect a diagnostic scanner (for example, Launch X431 or Delphi).
   • Go to section Body Control Module.
   • Run the command Reset Rain Sensor or Wiper Motor Relearn.
2. Check sensor calibration:
   • Make sure there are no scratches or film on the glass in the sensor area (behind the rearview mirror).
   • Turn on the ignition and press the button AUTO on the windshield wiper arm - the blades should make one full cycle.

Update BCM firmware (if available for your version). On Juke 2015–2017 releases had problems with brush synchronization, which were fixed in later software versions.

If after these manipulations the problem remains, check wiring from rain sensor to BCM. On Juke it runs under the instrument panel and often rubs against the metal frame. Pay attention to the connector C105 - its contacts can oxidize.

Prevention and care of windshield wipers

To brush on Nissan Juke served for a long time and did not cause problems, follow simple recommendations:

• 🌧️ Wash your brushes once a month with a soap solution - this will remove salt and dirt that destroy the rubber.
• ❄️ Do not operate windshield wipers on frozen glass. - this leads to deformation of the leashes.
• 🔧 Every 20,000 km check the play in the brush fastenings and tighten the nuts if necessary.
• 🔋 Lubricate the trapezoid silicone lubricant once a year to prevent corrosion and seizing.
• 🚗 When parking in the sun lift the brushes vertically so that the rubber does not deform due to heat.

Pay special attention winter operation. On Juke Due to the compact size of the windshield, the blades often freeze, which leads to increased load on the motor. Use winter brushes with protective cover or install heated brush parking area (for example, tape Webasto).

If you notice that the brushes have begun to “bounce” or leave streaks, do not wait for complete failure - replace rubber pads (article 28650-4M000 for original brushes). The cost of overlays is from 800 rubles per set, which is 3–4 times cheaper than new brushes.

FAQ: Frequently asked questions about Nissan Juke brushes

Can you install frameless brushes on the Juke?

Yes, but there are nuances. Frameless brushes (eg. Bosch Aerotwin or Denso Flat Blade) fit true to size (600 mm And 400 mm), but due to the shape of the windshield Juke may fit worse at the edges. We recommend choosing models with aerodynamic spoiler for better clamping at high speeds.

The brushes work, but leave streaks. What's the matter?

There are several reasons:

• Rubber wear - replace the entire pads or brushes.
• Glass contamination - use special cleaner (For example, Sonax Glass Cleaner).
• Wrong angle of the brush - adjust the leash (must be perpendicular to the glass).
• Oil on the glass (for example, due to a faulty crankcase ventilation valve) - check the engine ventilation system.

After replacing the battery, the brushes worked once and stopped working. What to do?

This is a typical problem for Juke with rain sensor. Reset errors via diagnostic scanner (command Wiper Motor Relearn). If you don't have a scanner, try:

1. Disconnect the battery for 10 minutes.
2. Turn on the ignition, press the windshield wiper lever to position OFF, then convert to INT and hold for 15 seconds.
3. If it doesn’t help, a flashing is required BCM.

What is the service life of original Juke brushes?

Factory brushes (28600-4M000) are designed for 100,000–150,000 cycles, which at average intensity of use is 2–3 years. However, in practice, the rubber begins to harden after 1.5 years due to exposure to UV rays and reagents. To extend service life, use silicone grease for rubber (for example, Gummi Pflege from Liqui Moly).

Can the motor be repaired or is it just a replacement?

In 90% of cases, the motor only needs to be replaced, but there are exceptions:

• If the problem is commutator brushes — they can be replaced (the set costs ~500 rubles).
• If it's jammed gear — it can be cleaned and lubricated, but this is a temporary solution.
• If the winding burns out, repair is impractical.

To disassemble the motor you will need special puller for retaining ring (article no. KV10114000).
