Low beam relay <em>Nissan Almera Classic</em>: location, replacement and diagnostics

Nissan Almera Classic (especially models B10 And N16) is one of the most popular budget sedans on the secondary market. But with age, even such reliable cars begin to show typical “diseases”, among which malfunctions of the lighting system occupy a leading position. If your low beam headlights stop working, the lamps blink or work randomly, the culprit is often low beam relay. In this article we will look at where it is located, how to check and replace it, as well as what nuances are important to consider when making repairs.

Relay failure is not a critical, but extremely unpleasant breakdown. Unlike a burnt-out lamp, which can be replaced in 5 minutes, problems with the relay can lead to complete lighting failure or a short circuit. At the same time, many car owners Almera Classic encounter difficulties in finding this element: depending on the year of manufacture and configuration, its location may differ. We have collected all the relevant information, including unique mounting block diagrams for different versions of Almera Classic, which cannot be found in standard manuals.

Where is the low beam relay located on Nissan Almera Classic

In most cases, the low beam relay is on Almera Classic located in fuse and relay mounting block, which is located in the cabin under the dashboard on the driver's side. However, there are several nuances here:

• 🔧 On models until 2006 (body B10) the mounting block is usually hidden behind a plastic cover to the left of the steering column. The low beam relay is marked there as R10 or Light Relay.
• 🔄 On Almera Classic N16 (2006–2012) the unit may be moved closer to the center console and the relay is labeled as Headlamp Relay or HL LO.
• ⚠️ On some export versions (for example, for Asian markets), the relay is placed in a separate block under the hood - next to the battery.

To accurately determine the location, pay attention to the mounting block diagram. There is usually a hint with symbols on the back of the block cover. If it is not there, use our table below.

Model Almera Classic	Year of manufacture	Relay location	Designation on the block
B10 (sedan)	1999–2005	Mounting block in the cabin (to the left of the steering wheel)	R10 or Light Relay
N16 (restyling)	2006–2012	Mounting block under the dashboard (closer to the center)	HL LO or Headlamp Relay
N16 (export versions)	2008–2012	Additional unit under the hood (next to the battery)	Fog/Head Relay

If you are not sure about the location, the easiest way is test the circuit with a multimeter. To do this, turn on the low beam and check the voltage at the relay contacts. When the headlights are turned on, it should appear on the working element 12 V.

Signs of a faulty low beam relay

A relay is an electromechanical device, and over time its contacts burn out, the springs weaken, and the winding can burn out. A breakdown can be recognized by the following symptoms:

• 💡 Low beam headlights don't turn on at all, although the lamps and fuses are working.
• 🔄 Low beam turns on spontaneously or works intermittently (flashes, dims).
• 🔊 When you turn on the headlights you can hear clicks from the mounting block, but the light does not come on.
• 🔥 Relay gets hot or smells like burning - a sign of burnt contacts.

It is important to distinguish a relay malfunction from other problems:

• 🔋 If they don’t work both headlights - most likely the relay or fuse is to blame.
• 💡 If it doesn’t light up one headlight — check the lamp, socket or wiring.
• 🔌 If they don’t work all lighting fixtures (including dimensions) - the problem may be main relay or fuse box.

⚠️ Attention! If the low beam relay is on Almera Classic starts to “click” without turning on the headlights - this is a sign short circuit in the circuit. Do not ignore the problem: this may lead to a fire in the wiring.

For accurate diagnostics, you can temporarily install a known-good relay (for example, from fog lights or a cooling fan - they are often interchangeable). If the headlights work after replacement, the problem is in the relay.

How to test the low beam relay with a multimeter

Checking the relay does not require special skills, but it will require multimeter (or at least a warning light on 12 V). Algorithm of actions:

1. Remove the relay from the mounting block. It is usually removed by lightly pressing the latches.
2. Inspect the contacts for melting, oxidation or carbon deposits. If they are damaged, the relay must be replaced.
3. Ring the winding:
   • Connect the multimeter probes to the terminals 85 And 86 (usually these are control contacts).
   • Resistance must be within 50–120 Ohm. If the device shows 0 (short circuit) or ∞ (break) - the relay is faulty.
4. Check the functionality of the contacts:
   • Connect 12 V to conclusions 85 And 86 (polarity is not important).
   • You should hear a click - this means that the contacts 30 And 87 closed up.
   • Test them with a multimeter: the resistance should be close to 0 ohm.

If the relay does not click or the contacts do not close, it must be replaced. In most cases the relay is Almera Classic cannot be repaired (unless you can clean the contacts, but this is a temporary solution).

Step-by-step instructions for replacing the low beam relay

Replacing the relay with Nissan Almera Classic takes no more than 10 minutes, but requires care. Follow the instructions:

1. Disconnect the battery (remove the negative terminal) to avoid short circuit.
2. Remove the mounting block cover:
   • On B10 - use a screwdriver to pry it off from the side (there are grooves there).
   • On N16 - press the latches at the top.

Find the low beam relay (see table above). It is usually located next to the headlight fuses (F10 or F11).

Remove the faulty relay slight rocking to the sides.

Install a new relay (analogue by catalog number or interchangeable).

Check the headlights before assembly.

If the headlights do not light up after replacing the relay, check:

• 🔌 fuse (it may burn out if short circuited).
• 🔧 Contacts in the mounting block - sometimes they oxidize.
• 💡 Lamps and sockets - perhaps the problem is not in the relay.

⚠️ Attention! On Almera Classic N16 after 2010, the mounting block may contain relay with diode protection. Install only original or certified analogs - cheap Chinese relays are often not compatible and can burn the light control unit.

Which low beam relay to choose for Nissan Almera Classic

Original low beam relay for Almera Classic has a catalog number 25230-3M000 (for B10) or 25230-4M010 (for N16). However, the original is expensive (from 800 rubles), and analogues work no worse. Here are the tested options:

Manufacturer	Catalog number	Price (RUB)	Notes
Nissan (original)	25230-4M010	800–1200	100% compatibility guarantee
Bosch	0 332 019 150	300–450	High quality, fits most versions
Hella	4RA 003 507-121	250–400	Good budget option
ERA	550107	150–250	Low price, but less resource

When choosing an analogue, pay attention to:

• 🔌 Contact type - they must match the original (usually 4-pin standard relay ISO 280).
• 🔋 Rated current - no less 30 A (for Almera Classic that's enough 20–40 A).
• 🔧 Availability of diode protection - important for models after 2010.

If you buy a disassembled relay, check its functionality before installation (see the section on diagnostics with a multimeter).

How to distinguish a fake Bosch relay?

The original Bosch relay has clear markings, smooth plastic without burrs and metal contacts with an anti-corrosion coating. Counterfeits often have a dull logo, a rough body and thin contacts that burn quickly.

Typical mistakes when replacing a relay and how to avoid them

Even something as simple as replacing a relay can lead to new problems if mistakes are made. Here are the most common:

• 🔌 Installing a relay of the wrong rating - for example, instead of 30 A put 10 A. This leads to melting of the contacts.
• 🔧 Ignoring oxidized contacts in the mounting block. Even a new relay will work intermittently.
• 💡 Fuse confusion - for example, instead of the low beam relay, the headlight relay is mistakenly replaced.
• 🔋 Failure to check lamps after replacing the relay. If the lamp burns out, the new part will quickly fail.

To avoid problems:

1. Always compare old and new relay visually.
2. Clean the contacts of the mounting block alcohol or special liquid (For example, Contact Cleaner).
3. After replacement check the operation of the headlights in different modes (near, far, dimensions).

⚠️ Attention! On Almera Classic N16 with the system automatic headlights (optional Auto Light) replacing the relay may change the settings of the control unit. After repair it may be necessary error reset via the diagnostic connector.

Frequently asked questions about the low beam relay on Nissan Almera Classic

Is it possible to temporarily drive without a low beam relay?

Technically yes, but it's not safe. Without a relay, the headlights will work directly, which can lead to:

• Overheating of the wiring (the relay protects the circuit from overload).
• Rapid failure of lamps.
• Short circuit due to power surges.

If the relay burns out on the road, it is better to temporarily connect the headlights via 20 A fuse (into the gap in the positive wire).

Why does a new relay burn out quickly?

This is a sign problems in the circuit. Possible reasons:

• Short circuit in wiring (check insulation).
• Malfunction of the light control unit (on N16 after 2008).
• Installation of high power lamps (more 55 W).

Solution: test the circuit with a multimeter or contact an auto electrician.

Where to buy a relay for Almera Classic, if the store does not have the original?

Analogues can be found:

• Auto parts stores (eg. Exist, Avtodelo).
• On AliExpress or eBay (search by catalog number).
• On disassembly (but check the functionality!).

Advice: if you urgently need to go, you can temporarily install a relay from fog lights or cooling fan - they are often interchangeable.

How to protect the relay from rapid wear?

The following will help extend the life of the relay:

• Regular cleaning contacts mounting block (once a year).
• Usage quality lamps (For example, Philips Vision or Osram Original).
• Avoidance prolonged operation of headlights at idle speed (especially in winter).
• Installation additional relay to unload the staff (relevant when using powerful lamps).
