Fuse box Nexia N 150. Electrical diagrams of Daewoo Nexia N100-N150

The fuse and relay box is located at the bottom left side of the instrument panel. To access the fuses, you need to remove the cover of the block. There is a table glued to the back of the cover indicating which electrical circuits are protected by each specific fuse. Next to the fuses their numbers are indicated.

Eighteen fuses are located on the front panel, and two fuses are located on the underside of the unit.

The color of the fuses depends on their rating: red - 10 A, yellow - 20 A, green - 30 A.

The fuse and relay box is installed under the protective cover in the instrument panel, to the left of the steering column. To remove the cover, pull it towards you.

Remove the cover. The location and purpose of fuses and relays are indicated on its inside. On the back of the block there are also relays and two fuses (see page 32).

Remove the fuse from the mounting block. A blown fuse can be identified by a break in the conductive strip. We insert the new fuse into the socket of the block until it stops.

We remove the medium-sized relay from the block by hand. Insert the relay into the block socket until it stops.

Before starting work, remove the wire terminal from the negative terminal of the battery. Before replacing the fuse, we eliminate the cause of its blown (we replace a faulty device or eliminate a fault in the electrical wiring). The new fuse must have the same markings and color as the one being replaced.

Attention! Do not install a homemade jumper wire or a larger fuse as a replacement - this may cause a fire.

Fuse box in the car interior: F1-F20 - fuses; 1 - large relay; 2 - small relay; 3 - warning signal block. The picture below shows the fuses and relays installed on the back of the unit.

To access the fuses installed on the back of the block, use a slotted screwdriver to pry the block from above, push it inside the panel and pull it out from under it. Turn the block on the wiring harness with the back side facing you. We install the block into the panel, first engaging the lower block clamps with it, and then the upper ones, helping ourselves with a slotted screwdriver.

In the Daewoo Nexia, the location of the fuses and relays can be seen below, under the steering column, by opening the decorative cover. Fuses and relays are hidden under it.

Once I inserted a DVR into the cigarette lighter of my Nexia, but it turned out to be defective and shorted. It was on the move, and my dashboard immediately went dark and the battery icon came on. I thought the generator had broken down. Then I found this article and realized that the fuse had simply blown out.

Fuse box in Nexia

Fuses on Nexia are responsible for the safety of electrical appliances. When a short circuit occurs, the fuse burns out first, thereby protecting the electrical appliance. The fuse box diagram for Nexia 8kl and 16kl are identical and for Nexia n100 and n150 the blocks are also interchangeable.
Every self-respecting motorist should have such a diagram at hand. Also, replacing fuses should be done with the engine turned off.
The Nexia has a double fuse box; the main fuses and relays are located on the outer visible side, and the remaining relays are located on the reverse side.

To differentiate between each other, fuses come in several colors. Each color has an amp rating.

Red – 10 Amps

Blue – 15 Amps

Yellow – 20 Amps

Green – 30 Amps

Fuses used in Nexia

Location and purpose of fuses

(Click on the fuse you are interested in and find out what it does)

	10A	10A	15A	20A	10A	10A
	30A	20A	30A	30A	10A	30A
	20A	30A	20A	30A	10A	30A

Find out which fuse is responsible for what below.

• Fuse F1 Electronic Engine Control Unit (ECU) - 10A

This fuse is responsible for powering the brain; if you remove this fuse, the car will not start.

• Fuse F2 Tail lights and license plate lights - 10A

If your license plate lights and side lights do not work, check this fuse.

• Fuse F3 The fuse was on the brain, but in some models. - 15A

Also a fuse for the brain, but in most cars there is an empty space here.

• Fuse F4 High beam - 20A

The fuse is responsible for the operation of both high beam bulbs at once, so if the high beam does not light, then check this fuse. If neither the right nor the left high-beam headlight lights up, then the reason is most likely in the fuse; if it doesn’t light up on one side, then the light bulb has burned out.

• Fuse F5 Low beam on the left side and left electric headlight adjustment - 10A

Low beam light with electric beam direction corrector, if your corrector does not work and the low beam does not shine, then check the fuse

• Fuse F6 Low beam on the right side, right headlight range control - 10A

Same as f5, but on the right side of the car

• Fuse F7 Fuel pump (fuel pump in the gas tank) - 30A

The fuel pump has a 30 Amp fuse; it is not recommended to install a larger one.

• Fuse F8 Hazard signal, side turn lamps (turn signals) - 20A

The hazard light may short out the light, if this fuse is overheated, then check the hazard light or turn signals

• Fuse F9 Windshield wipers - 30A

If the windshield wiper doesn't work, it's not a fact that it's a fuse, but it's worth checking

• Fuse F10 Fuel filler neck (fuel door electric lock activator) - 10A

In winter, a common problem is that the hatch does not open; if you press the button too much, most likely the electric motor will fail, but before that, check the fuse

• Fuse F11 A/C compressor (relay) - 10A

According to the pinout of the fuse diagram on the Nexia, there is a fuse for the air conditioner; if there is no air conditioner, there is no fuse.

• Fuse F12 Cooling system radiator cooling fan (low speed) - 30A

An important fuse, always check it to avoid problems with engine cooling.

• Fuse F13 Dashboard, cigarette lighter, horn, glove compartment light - 20A

If this pre knocks you out, it means there is a short circuit somewhere. As soon as this fuse burns out, you will immediately understand that the instrument panel will go out and the cigarette lighter will stop working.

• Fuse F14 Nexia cooling fan (maximum speed) - 30A

Always keep the fuse intact so that lack of cooling does not damage the engine.

• Fuse F15 Interior lighting bulbs, radio antenna - 20A

If the light in the cabin does not light, then the fuse or light bulb is to blame. Check the fuse first

• Fuse F19 responsible for the air conditioner
• Fuse F20 responsible for fog lights

Fuses protect a device or device from failure. They burn out when a high load is applied to the circuit, so it is strictly forbidden to install a larger fuse, as this can lead to a fire in the wiring. If the fuse does not trip and does not burn out, it means that the fuse rating was not selected correctly. It is measured in Amperes, you can buy fuses for Nexia in any store, and if you don’t have spare ones, you can pull them out from another place that does not affect the normal operation of the car - this is the air conditioner, antenna and interior lighting.

It is also forbidden to install temporary jumpers instead of fuses; this can also end badly for your Nexia.

Not only the functioning of electrical equipment, but also of the vehicle as a whole depends on the performance of fuses. Therefore, from time to time you need to check the unit, even if all elements of the system are working normally. In this article we will tell you where the Daewoo Nexia fuses are located and how to replace them if necessary.

Location and electrical diagram

The Nexia uses DC electrical equipment with a nominal voltage of 12 volts. All energy consumers in a given vehicle are connected according to the same principle. In particular, the negative terminals of the equipment are connected by ground (that is, connected to the body of the car), which, in turn, acts as a second wire. The power supply for all devices comes from two sources: if the engine is not running, then from the battery (battery), if it is running, then from the generator.

The fuse box (hereinafter referred to as the BP) and relay in the Daewoo Nexia car is located at the bottom of the car’s dashboard. Specifically, it is located on the left side of the instrument panel. In vehicles produced before 2008, the PSU is marked N100, and in younger cars - N150. Let us tell you right away that in terms of their design, circuit and purpose of components, the power supply units are absolutely identical. The only difference is in access to them due to the design features of the torpedo.

We present to your attention a diagram of the power supply unit and relay with a description of all the elements.

You may also find the relay description useful.

Detail number	Purpose
K1	This relay is responsible for the operation of the ventilation device of the cooling system. Specifically, this relay is called a “high fan speed relay.”
K2	This element ensures the functioning of the lamps. Accordingly, if it fails, you will not be able to signal to other drivers about your intention to turn.
short circuit	Responds to the functioning of the fuel pump. If this relay fails, the operation of the fuel pump will be impossible and, accordingly, it will not be possible to start the engine.
K4	Responsible for the operation of the front and rear fog lights.
K5	Provides operation of side lamps and fog lamps.
K6	If this relay breaks down, the operation of the headlight lamps (responsible for low and high beam) will be impossible.
K7	The failure of this component, which is responsible for the speed of the cooling system fan, indicates that the engine may overheat and, as a result, boil. This part must be replaced immediately if it fails.
K8	A breakdown of this relay indicates that the compressor clutch is not working.
K9	Responsible for the operation of the steering wheel horn.
K10	Also ensures the performance of headlight lamps.
K11	This component ensures the functionality of a melodic signal (sound when doors are opened, seat belts are not fastened - depending on the configuration).
K12	The relay is responsible for activating the fourth speed of the heating system fan. If it fails, then at too low temperatures the heater will not be able to operate at full capacity.
K13	The ignition system ensures operation. If the relay burns out, starting the engine will be impossible.
K14	Responsible for the windshield wiper device.
K15	Rear window heating timer.

Removal and replacement process

If you need to replace a fuse, remember that you should use a new element of the same power as the burnt one.

Of course, fuses are interchangeable with each other, however, keep in mind the fact that different circuits in your car's wiring require different protection. If you don’t know what power the burnt-out element has, then just look at it: there are numbers on the part, this is the power.

If you recently replaced the element, but it burned out again almost immediately, this may be due to a short circuit. First, you need to eliminate the cause itself, that is, check the section of the wiring for which the relay or fuse is responsible, and get rid of it. In practice, usually the main reasons for the systematic failure of elements is a broken or worn-out wire. Therefore, before replacing the element, it would be better to replace it.

Also, refrain from installing homemade devices. Very often, motorists make such mistakes, but such actions do not lead to anything good. So, let's start replacing the fuses.

1. Open the hood of your car and find the battery. Before you climb into the unit, you need to disconnect the battery; to do this, disconnect the negative terminal.
2. Find the place where your power supply is installed and remove the protective plastic cover from it.
3. Then you will need to find the element that you think has failed. If your stove or cigarette lighter does not work, this does not mean that the fuse has failed. The problem in operation may lie directly in the device itself. However, the block needs to be checked first. To find the fuse you need, you can use the diagram provided on our website or look at the back of the cover. It shows the removal of the power supply with the parts responsible for the electrical equipment.
4. If the part really fails, then the fusible thread located inside it will be broken or burnt out. But if you notice that the plastic body of the element itself has melted, then this indicates not only its breakdown, but also a short circuit, as a result of which it melted. It should also be added that sometimes the part is visually intact, although the connection inside the thread is broken. You won't be able to identify any damage just by looking at it. Then you will have to check the condition of the device using a special ohmmeter device or insert a new one into the socket of the burnt-out element. Remove the part using special pliers.
5. So, install the device with the required rating in place. As stated above, the rating (that is, the numbers on the fuse) must match. Check the functionality of electrical equipment whose operation was previously unsatisfactory to you.
6. To replace the relay, follow similar instructions. First, determine which relay needs to be replaced. Remove it with your hands while pulling up and down. Do this carefully so as not to damage the nest. To check the functionality of the relay, install in its place one in which you are absolutely sure that it is working.
7. After completing all the replacement work, replace the cover of the mounting block, and then connect the battery.

Locate the fuse that needs to be replaced. If you have difficulty finding it, then use our manual or look at the back of the mounting block cover - the diagram and purpose of all the parts are described there. Pull it out and replace it with a new one.

It all started with a mileage of 55 thousand km, the contact group melted, replaced it, drove it for 1 thousand km, it closed again, yesterday I installed an additional unloading relay "30-15" (Made in Italy) 30A, with a ceramic block, the KG is cold as snow, but it became the relay gets very hot (For clarity, I wet my finger with saliva and touched contact 30 of the relay, my mouth began to hiss) the relay gets a little warm when the equipment is turned off and heats up more and more as various devices are turned on, I noticed that the most noticeable thing is the low beam. The low beam is connected through the KG, but since I unloaded it, the relay itself is heating up, it seems that the “+” on the light relay comes from the KG “15” and the relay coil goes to the steering column switch, am I thinking correctly?

Actually the question itself is where the low beam relay is located, I want to try to power this relay from the battery...

If I'm not mistaken, then in the diagram the main routes "30", "15" and "15A" are the wires that are on the KG, the diagram shows that the relays are connected to "30", and this is the main wire that comes from the battery, which is always under tension. How do the low beams turn off when you turn off the ignition??? Logically, if the low beam relay is powered from “30”, then there should be 1 relay on the steering column switch, 2nd relay on the KG, but there is only one relay!!! After all, the voltage is high, and there are thin wires on the steering column switch, which means the relay is 100%, then it turns out that the “+” to this relay goes through the CG “15”, according to the idea, the low beam should not go through any other contact on the CG, because . When the low beam is on, it is “15” that heats up. Correct me if I made a mistake somewhere and my logic is not correct.

My logic didn't let me down...
Today I went on business, the one way trip is 7 km, the first 7 km I drove without headlights, the relay with which I unloaded the CG was a little warm, I drove back the same 7 km and turned on the headlights, upon arrival the relay got hot again in the same way that drool was hissing on the relay on contact "30"

Installing an additional relay on the KG

Here's what happened:
