The situation when by car Nissan Almera Classic Side lights stop lighting is one of the most common problems in the electrical part of the body. This is not just an aesthetic defect, but a direct violation of traffic rules, making your car less noticeable at night. Owners often encounter the fact that when they turn the key to the “dimensions” position, the light does not appear either in front or behind, or only one side is on.
There can be many reasons for this behavior: from a banal lamp burnout to a serious wiring break or relay failure. Owners Nissan Almera Classic People often underestimate the ease of diagnosing this system by trying to disassemble the entire instrument panel at once. In fact, in most cases, the problem is solved quickly and without an expensive call to the service center, if you know exactly where to look for the problem.
Basic diagnostics and testing of incandescent lamps
The first and most obvious step when identifying non-functioning lights is to visually and physically inspect the light sources themselves. On the model Nissan Almera Classic W5W (or T10) type lamps are used for the front and rear lights. These elements have a low resource and often burn out due to power surges or vibration.
First, you need to remove the interior lamp and make sure that the problem is not in the switch itself, but in the lighting circuits. If the lights do not light up at all, check the condition of the filaments in the lamps. Sometimes a thread may be visually intact, but have microcracks that only appear when vibrated.
- 🔍 Visually inspect the glass bulb of the lamp for blackening or broken thread.
- 🔦 Use a multimeter in continuity mode to check the continuity of the circuit inside the cartridge.
- 💡 Try replacing the suspicious lamp with a known good one from another unit.
Sometimes the problem lies not in the lamp itself, but in the oxidation of the contacts inside the base. Moisture that gets into headlights or flashlights eventually leads to the formation of a coating that blocks the passage of current. Cleaning the contacts with fine sandpaper or alcohol will often restore system functionality without replacing parts.
It is important to understand that if the dimensions do not light up on both sides at the same time, the likelihood of two lamps burning out at the same time is extremely small. This immediately suggests a problem in a common section of the circuit, a fuse or a relay, which we will examine in the following sections.
Analysis of fuse box and relay
Electrical system Nissan Almera Classic protected by a system of fuses located in the engine compartment and in the passenger compartment. If replacing the lamps does not help, the next step is to check the fuse that controls the side lights. This is usually a fuse marked TAIL or GAZ depending on the year of manufacture and configuration.
Locate the fuse box under the hood. The cover usually has a layout of the elements where the critical element can be found. Remove the suspect fuse and carefully inspect its metal jumper. If it melts or breaks, it means there is a short circuit in the circuit.
- 🔧 Use a special plastic clamp (tweezers) to remove fuses so as not to damage them.
- 📊 Replace the burnt out element with a new one with exactly the same rating (amperage).
- ⚡ Never install a fuse with a large rating, this may lead to a fire in the wiring.
Next to the fuses there is often a relay for turning on the side lights. On Nissan Almera Classic it can be integrated into a common relay block or stand alone. If the fuse is intact, but no current is supplied to the lamps, the problem may be sticking relay contacts or coil windings.
⚠️ Attention: If the new fuse blows instantly after installation, this is a sure sign of a short circuit in the wiring. Do not try to solve the problem by replacing the fuse with a more powerful one - this will lead to melting of the insulation and a fire.
To check the relay, you can use the substitution method: take a similar relay (for example, from a horn or a fan, if they have the same pinout) and install it in place of the suspicious one. If the lights light up, it means the relay is faulty and needs to be replaced.
- Front
- Rear
- Both sides at once
- Nothing is lit, but the lamps are intact
Search for breaks in wiring and contacts
If the fuses and lamps are good and the relay is working, the reason lies in the wiring. Cars Nissan Almera Classic are already quite old, and the wire insulation may degrade. Breaks often occur in places where the harnesses bend, especially during the transition from the body to the doors or trunk.
Particular attention should be paid to the harness going into the trunk lid. When opening and closing the cover frequently, the wires in the rubber corrugation fray. As a result, the contact to the rear dimensions disappears. To check, you need to carefully cut the corrugation and inspect the wires for breaks.
- 🔌 Inspect the connectors on the headlights and taillights for oxidation or moisture.
- 🔍 Check the integrity of the wire insulation where they enter the body.
- 🛠️ Use a multimeter to test the circuit from the fuse to the lamp.
Sometimes the problem is poor ground contact. Oversized lamps often have a common negative wire that is attached to the car body. If the mounting location is oxidized or weakened, current will not circulate. Find the grounding point, clean the metal until it's shiny, and tighten the bolt tightly.
☑️ Wiring diagnostics
⚠️ Attention: When checking the wiring with a multimeter, be sure to disconnect the battery. Shorting the test leads to live wires can cause a spark and damage the meter.
In some cases, wiring repairs require soldering and high-quality insulation with heat shrink tubing. It is not recommended to simply twist the wires and wrap them with electrical tape, since over time the electrical tape dries out and the contact disappears again. Use special terminals or soldering followed by protection.
Diagnostics of the switch block and steering column lever
The next component that can cause a malfunction is the steering wheel light switch itself. In the mechanism Nissan Almera Classic Over time, the contacts burn or oxidize due to dust and moisture getting inside the plastic case.
When the lever is turned to turn on the dimensions, the mechanism must close a certain group of contacts. If there is carbon deposits inside the block, the current will not pass further and the lamps will not light up. Diagnostics of this unit requires removing the plastic steering column cover and accessing the switch connector.
- 🔩 Carefully remove the lower and upper parts of the steering column cover by unscrewing the screws.
- 🔌 Disconnect the connector from the steering column switch to visually inspect the contacts.
- 🧹 If there is carbon deposits, try cleaning the contacts with a cotton swab dipped in contact lubricant.
Sometimes simply blowing the contacts with compressed air or treating them with a contact cleaning spray (for example, WD-40 Specialist or equivalent) helps. If the plastic inside is deformed or the springs are weakened, a complete replacement of the switch block will be required.
How to remove the steering column switch
To remove it, you need to unscrew the two screws from the bottom, release the clamps and carefully pull the block out of the steering column housing. Be careful with the wiring going to the airbag if it runs nearby.
If you are not confident in your skills in working with steering electronics, it is better to entrust this work to specialists. Rough handling can lead to problems with the signal or even the airbag.
Specific problems of Nissan Almera Classic models
Owners Nissan Almera Classic often face a unique problem: failure of the flashlight or headlight housing itself due to poor sealing. Moisture getting inside causes corrosion of lamp bases, which leads to poor contact even with a new lamp.
Another characteristic feature is the oxidation of the power pads in the rear lights. The plastic of the pads becomes brittle over time and can crack, resulting in loss of contact. In such cases, it is necessary to replace not only the lamp, but also the entire connector.
It is important to note that on some modifications there may be a problem with the control relay or body control module (BCM), but this happens less frequently. The main reason for the non-functioning dimensions on this model is the oxidation of the contacts in the rear lights due to condensation.
To solve the problem of headlamp sealing, you can use special sealants for automotive optics. This will prevent moisture from getting inside and extend the life of the electrical equipment. Regularly checking the condition of the headlight seals will also help avoid problems.
Before purchasing a new lamp, check whether it fits your socket. Sometimes cheap analogues have slightly larger bases and are poorly fixed in the socket, which leads to poor contact.

If all of the above methods did not help and you did not find the cause of the problem, the problem may be deeper. This could be a malfunction of the lighting control unit itself or a complex wiring diagram that requires professional diagnostic equipment.
Specialized services use diagnostic scanners that can read errors from control units. This allows you to accurately determine which signal is not reaching the consumer. The technicians also have access to electrical wiring diagrams, which makes it easier to find breaks.
- 🛠️ Professional diagnostics will reveal hidden breaks and short circuits.
- 💰 The cost of repairs from specialists is often lower than independent attempts to purchase unnecessary parts.
- 🔋 Experts will be able to restore the wiring with a guarantee of quality and safety.
You should not delay repairs, as non-functioning dimensions make your car dangerous for other road users. At night, you become invisible, which increases the risk of an accident. It is better to spend time on diagnostics now than to pay fines or repair the consequences of an accident.
If you decide to contact the service, be sure to clarify that the problem is in the dimensions, and not in the low or high beam. This will help the technician quickly navigate and prepare the necessary equipment to test this particular circuit.
Why can the lights light up but not work when the headlights are turned on?
This may indicate a malfunction in the switch block or an open in the mode switching circuit. Often the problem lies in the contact inside the steering column lever, which is responsible for the transition from the dimensions to the low beam.
Is it possible to drive with the lights not working during the day?
Technically, you can drive to the service station, but this is a traffic violation. In the dark or in poor visibility conditions (rain, fog), operating a vehicle with inoperative dimensions is prohibited and will result in a fine.
How often do headlight bulbs need to be changed?
The W5W lamp life is about 1000-2000 hours. Depending on the intensity of use, replacement may be required every 1-2 years. It is recommended to change lamps in pairs to avoid differences in brightness and color.
What should I do if the fuse blows immediately after replacement?
This is a short circuit signal. It is necessary to disconnect the battery and check the wiring for damage, melted insulation or positive contact with ground. Do not turn on the ignition until you find the cause of the short circuit.
