Trunk button on Nissan March - a seemingly simple element, but its malfunction can cause a lot of inconvenience. Especially if the trunk lid is stuck in the open or closed position, and the electronic drive refuses to respond to pressure. Owners March (especially models K13 2010–2019) often encounter problems in the operation of this mechanism - from banal oxidation of contacts to failure of a microswitch or electric motor.

In this article we will analyze all possible reasonsby which the trunk button Nissan March may not work, and we will also give step-by-step instructions for diagnosis and repair. From the simplest cleaning of contacts to replacing the drive, you will learn how to restore functionality without calling for service. We will pay special attention a typical problem with electric drive models: fuse F35 (10A) trips when the mechanism is overloaded, which often goes unnoticed during a superficial check.

The design and principle of operation of the trunk button

On Nissan March The trunk opening button can be implemented in two versions:

  • πŸ”˜ Mechanical button (on early models before 2013) - connected to a cable that physically opens the lock.
  • ⚑ Electronic button (on restyled versions after 2013) - sends a signal to the electric drive that controls the lock.

The electric version includes:

  • πŸ”Œ Microswitch in the cabin (usually located on the panel to the left of the driver or on the key).
  • πŸ”‹ Drive motor in the trunk lock mechanism.
  • πŸ›‘οΈ Fuse F35 (10A) in the fuse box under the hood.
  • πŸ“Ά Body Control Module (BCM), signal processing.

When the button is pressed, the signal is sent to BCM, which activates the drive relay. If at least one of the chain elements fails, the trunk will not open. For example, oxidation of contacts on the electric motor connector (connector B127) or a wire break in the corrugation between the body and the trunk lid are common causes of failures.

Symptoms of a faulty trunk button

Problems with the trunk button Nissan March manifest themselves in different ways. Here are the key symptoms that will help diagnose the cause:

Symptom Probable Cause Verification method
The button does not respond, but the trunk opens with the key Microswitch faulty or open circuit Ring the button contacts with a tester
The relay click is heard, but the drive does not work The electric motor has failed or the mechanism is jammed Apply 12V directly to the motor
The button works every once in a while Oxidation of contacts or poor ground wire Clean the connectors, check the ground on the body
Fuse F35 keeps blowing Short circuit in drive circuit Ring the wires on the short circuit, check the motor

If the trunk opens with the key, but does not respond to the button, the problem is most likely in the electrical part. If the key does not help, the mechanical lock or cable is to blame. Often found on electrically powered models. Reducer gear jamming due to dirt or corrosion.

⚠️ Attention: If you hear the sound of a running motor when you press the button, but the lid does not open, stop trying immediately! This is a sign of mechanical jamming, and further efforts may lead to cable breakage or plastic gears breaking.

Fault diagnosis: step-by-step instructions

To accurately determine the reason why the trunk button does not work Nissan March, follow this algorithm:

  1. Check fuse F35 (10A) in the block under the hood. It is responsible for the trunk drive chain. If it's burned out, replace it and try again. If the fuse burns again, there is a short circuit in the circuit.
  2. Make sure there is power to the button. Remove the covering near the button and use a multimeter to check the voltage at the contacts when pressed (there should be 12V).
  3. Ring the circuit from the button to the BCM. Use the electrical diagram to March (connector B127 on the control unit).
  4. Apply voltage directly to the electric motor. If the motor does not respond, it is faulty. If it buzzes, but the lid does not open, there is a mechanical problem.

For direct motor test:

  1. Remove the trunk lining (unscrew the 4 plastic clips).
  2. Find the electric drive connector (usually black, 2 wires: red (+12V) And black (mass)).
  3. Connect the wires directly to the battery. If the motor does not spin, replacement is required.

If the motor hums but the lid does not open, remove the trunk trim and manually turn the gearbox. Often helps remove dirt or rust blocking the mechanism.

Mechanical button repair (cable drive)

On Nissan March Until 2013, the trunk button was connected to a cable, which stretched or broke over time. If the button is pressed but the trunk does not open, follow these steps:

  1. Remove the trim around the button (usually secured with latches).
  2. Check the cable fastening to the button. Often it just jumps off the latch.
  3. Make sure the cable is not broken. If the shell is intact, but the inner conductor is broken, replacement will be required.
  4. Lubricate the cable silicone grease if it is tight in the shell.

If the cable is torn, you can replace it yourself:

  • πŸ”§ Buy a cable repair kit for Nissan March (article 72511-4M000).
  • πŸ”— Disconnect the old cable from the button and trunk lock.
  • πŸ“ Pass the new cable through the same guides and secure it in place.
  • πŸ”„ Adjust the tension - the lid should open without effort.
⚠️ Attention: When replacing the cable, do not mix up the sides! On March The cable has asymmetrical ends for the button and lock. If you install it incorrectly, the button will be pressed, but the trunk will not open.

Replacing the trunk drive electric motor

If diagnostics show that the electric motor is faulty, it can be replaced without dismantling the entire lock. For Nissan March (K13) suitable motor with article number 28550-4M000 or analogues 28550-4M00A, 28550-4M010.

Step by step instructions:

  1. Disconnect the negative terminal of the battery.
  2. Remove the trunk lining (unscrew 4 clips and 2 bolts 10 mm).
  3. Disconnect the power connector from the motor (black connector).
  4. Unscrew the 3 motor mounting bolts (Torx T20).
  5. Remove the old motor and install the new one, securing it with bolts.
  6. Connect the connector and check operation.

The cost of a new motor is from 3,500 to 5,000 rubles (for 2026). At salvage yards you can find a used version for 1,500–2,500 rubles, but be prepared for the fact that his resource may already be running out.

How to check the motor without removing the trim?

If you don’t want to disassemble the trunk, you can check the motor β€œby ear”:

1. Press the trunk release button.

2. Listen to the sound from under the cladding.

- The relay clicks, but the motor does not hum β†’ open circuit or faulty motor.

- The motor hums, but the lid does not open β†’ mechanical jamming.

- There are no sounds β†’ the problem is in the button, fuse or BCM.

Cleaning and lubricating the trunk lock mechanism

Often the trunk button Nissan March stops working due to simple contamination of the mechanism. Dust, dirt and corrosion block the gears of the gearbox or cable. We recommend cleaning the mechanism once every 2–3 years or at the first sign of tightness.

What you will need:

  • 🧴 Silicone grease (for example, Liqui Moly Silicone-Spray).
  • 🧹 Brush with hard bristles.
  • πŸ”§ Screwdriver set (Torx T20, flat).
  • 🧻 Rags and WD-40 for cleaning.

Procedure:

  1. Remove the trunk lining (see instructions above).
  2. Clean the mechanism from dirt with a brush and WD-40. Pay special attention to the gearbox gears and cable guides.
  3. Apply silicone grease to:
    • πŸ”„ Gearbox gears.
    • πŸ”— Cable (if it is not in a shell).
    • πŸ” Trunk lock.
  • Check the movement of the lid - it should open smoothly, without jerking.
    • πŸ’‘

    After lubrication, do not use graphite or lithium lubricants - they attract dirt and accelerate wear of the mechanism. Silicone grease is optimal for plastic and metal parts.

    Common repair mistakes and how to avoid them

    Many owners Nissan March make the same mistakes when trying to fix the trunk button. That's what can't do:

    • ❌ Ignore fuse F35. If it burns out, simply replacing it is not enough - you need to find the cause of the short circuit (most often it is frayed wires in the corrugation of the trunk lid).
    • ❌ Lubricate the mechanism with oils based on petroleum products. They corrode plastic gears and attract dust.
    • ❌ Apply force when jammed. This leads to the cable breaking or the plastic parts of the lock breaking.
    • ❌ Buy cheap analogues of cables or motors. They often fail after 1–2 months.

    Another common mistake is incorrect cable adjustment after replacement. If it is tightened, the button will be difficult to press; if it is loosened, the trunk will not open. Optimal tension: when you press the button, the lid should open with a slight click, without delay.

    If after repair the button works, but the trunk does not open the first time, check:

    • πŸ”‹ Reliability of contacts on the motor connector (sometimes they oxidize in 1-2 months).
    • πŸ”Œ The quality of the β€œground” on the body (check the wire from the motor to the body).
    • πŸ”„ Movement of the gearbox gears (re-lubrication may be required).

    FAQ: Frequently asked questions about the trunk button Nissan March

    Is it possible to open the trunk if the button is broken and the key does not help?

    Yes, there are two ways:

    1. Through the salon: Fold down the rear seats and access the trunk lock from the inside. On March To do this, you need to remove the plastic plug behind the seat back.
    2. Emergency cable: on some models there is a hatch under the rear bumper for access to the emergency release cable (pull the orange loop).

    If none of the methods work, you will have to drill the lock or contact an auto electrician for a direct connection to the drive.

    Why does fuse F35 keep blowing?

    This indicates short circuit in the trunk drive circuit. Most often the culprits are:

    • πŸ”Œ Frayed wires in the corrugation between the body and the trunk lid.
    • πŸ”‹ Short circuit in the electric motor winding (check the resistance with a multimeter).
    • πŸ’§ Moisture getting into the motor connector (oxidation of contacts).

    To find the problem, unplug the motor connector and check if the fuse blows when the button is pressed. If not, the motor is at fault. If yes, look for a short circuit in the wiring.

    How much does a service repair cost?

    The cost depends on the cause of the breakdown:

    • πŸ”§ Replacing the cable: 1,500–2,500 rubles (with work).
    • ⚑ Replacing the electric motor: 4,000–6,000 rubles (with work).
    • πŸ”Œ Electrical circuit diagnostics: 1,000–1,500 rubles.
    • πŸ” Trunk lock repair: 2,000–3,500 rubles.

    Do-it-yourself repairs will cost 2–3 times less, but require time and tools.

    Is it possible to install an alarm with automatic trunk opening?

    Yes, but there are nuances:

    • πŸ“Ά On March with an electric trunk, you can connect an alarm (for example, StarLine or Pandora) to the motor control wires. Will be required diode isolationso as not to burn the alarm unit.
    • πŸ”§ On mechanical versions you need to install additional electric drive (for example, from Nissan Note), which will cost 8,000–12,000 rubles.

    It is better to entrust the installation to professionals - an incorrect connection can cause damage BCM.

    Where is fuse F35 located?

    On Nissan March (K13) fuse box is located under the hood, next to the battery. fuse F35 (10A) is responsible for:

    • Trunk drive.
    • Luggage compartment lighting.
    • Rear wiper control circuit (on some versions).

    The fuse box diagram is usually pasted on the inside of the cover.
