A new relay or fuse should be installed in place of a failed one only after the cause of the malfunction has been determined and eliminated.

It is allowed to use only standard fuses designed for a certain rated current (the rated current of the fuse is indicated on its body).

The Chevrolet Lanos has earned an excellent reputation and is in demand among domestic drivers. Almost everyone notes its reliability, unpretentiousness, efficiency and ease of maintenance.

Chevrolet Lanos car

The design is really simple and thought out to the smallest detail. The developers also paid attention to the electrical equipment protection system, placing fuses in two blocks, as well as in one additional block with a relay.

But a situation where some electrical consumer fails can happen even on such a reliable vehicle. For example, very often the cigarette lighter, lighting or heating fails. Some drivers immediately get lost and go to a service station, spending a lot of money for something they could do on their own in just a few minutes.

Chevrolet Lanos cars are purchased mainly by people with average incomes, so performing many jobs is very important for many.

Removal and replacement instructions

Replacing fuses and relays on a Chevrolet Lanos, both under the hood and in the interior unit, is almost identical.

Preparation

Before proceeding to replacing the fuse, we recommend de-energizing the system. To do this, turn off the ignition and, to be on the safe side, take out the key. It would also be a good idea to disconnect the negative terminal of the battery.

If some consumer fails, the first thing we do is determine which block it is located in. This is done very simply. We look at its number in the decoding, then find its location on the diagram.
If the electrical fuse is located in the engine compartment, then we need to remove the steam exhaust hose and open the cover. If the element we need is located in the interior compartment, then it is enough to open the lid itself. These are all the differences between replacing a fuse in the engine compartment or the passenger compartment.
Next, using tweezers, remove the problematic fuse. We examine it, trying to visually determine whether it is intact or burnt out. It is better, of course, to do this work using a tester. Although it should be visually noticeable that the conductive part is burnt out, and in some cases the plastic shell itself may be melted.
Now we need to remove a fuse of similar rating from the spare set and install it in place of the blown one.
Replace the “-” terminal of the battery. We start the car.
We check the work of the consumer.

If the problem was in the fuse, then the equipment should work. If the fuse blows again, then the problem is much more serious. It is necessary to inspect the wiring and the consumer itself.

Replacement

We started the article with unexpected malfunctions of electrical appliances. Once you have an idea of what the Chevrolet Lanos fuse box looks like and what its elements are responsible for, you can begin troubleshooting. The most common failure is the cigarette lighter, so let's look at the replacement process using it as an example.

First of all, you need to make sure that the cigarette lighter is really not working. There may be several reasons why it stopped performing its direct duties or charging your gadgets:

blown fuse;
clogged contact;
inconsistent charger contact due to its configuration;
problems with wiring or contacts.

The last case is very rare and least likely. We make sure that the nest is not filled with debris, dust, ash or tobacco. If so, clean the nest. Then check if your gadget's charger fits well into the socket. Perhaps this will be the problem and will be solved by purchasing a new charger. So, if all of the above problems do not affect you, then you need to replace the fuse. It is located in the indoor unit (read above for how to get to it) and is marked F10. Using tweezers, remove the old PP, make sure that it is really burnt (black, charred, melted) and insert a new one of the same rated current (15 A) in its place.

Also, Chevrolet Lanos car owners are faced with the fact that the car will not start. This problem can often be solved by replacing the fuel pump fuse. Watch the replacement video:

Recommendations for use

Every prudent driver must have a set of electrical fuses of various ratings, this is especially necessary for those drivers who drive long distances. They cost pennies, but at some point they can help out a lot.
Sometimes, if some equipment fails, but the electrical fuse is intact, it is enough to move it a little in the connector. Perhaps carbon deposits or rust caused the chain to break.
Replace only with an item of similar value. If you put in less, it may burn out immediately. If it is more, it will not be able to properly protect the equipment.
Under no circumstances should you install wires or bugs, which in some situations can cause the car to catch fire.

Sorry, there are no surveys available at this time.

Block in the control panel

Finally, the third block is located in the instrument panel. It is responsible for fewer actions in the car system, but is also significant and important. Below is a table of the main functions that this unit provides to the vehicle.

Number	Designation
1	Tail lamp relay
2	Fan relay
3	Windshield wiper relay
4	Relay for turning headlights and hazard lights

Thus, you can see that each block is responsible for a specific area in the car system, allowing you to drive it comfortably and safely. All fuses and relays are aimed at improving the operation of the vehicle.

Often, car owners are faced with a faulty electrical appliance and do not know what to do next. It would seem that the electrical circuit of the car is too complex and not everyone can find the cause of the malfunction. Is it really necessary to take your Chevrolet Lanos to an electrician in case of any breakdown? Of course not. The most common reason that an electrical appliance stops working is blown fuses. Therefore, before you panic and go to the mechanic, you need to look into the fuse block (BP) of the Chevrolet Lanos and inspect it.

Modern cars traditionally have two fuse blocks: the main (or mounting) and the additional. Since this is not a completely correct gradation (neither one is more important than the other) many people call them the inner and outer blocks. The power supply unit is equipped with fuses (FC) of various rated currents and relays. Both those and other power supply elements serve to protect electrical circuit devices. PPs are instant action elements, that is, they burn out at the moment when the current in the circuit exceeds the rated value (which is individual for each PP). Relays protect circuit elements from severe overloads: from short circuits and the accompanying enormous voltage in the circuit.

If any device or instrument that is part of the electrical equipment of your car fails, you must first check the serviceability of the fuses of the failed electrical equipment, and then all other fuses. To do this, you need to find the fuse (or fuses) that protects the circuit of the failed device or appliance. If all fuses are in order, then the cause of the malfunction must be sought in the electrical equipment itself. It is necessary to replace blown fuses and check the functioning of failed vehicle devices.

Procedure for checking an electrical relay

You can find out the reason why the fuel pump stops working by checking its switching circuits, which includes a relay. It is an electrical device that, at the command of the electronic power supply, provides power to the pump motor, and when the contacts open, it stops this supply. Its malfunction is often associated with a breakdown of its coil or due to oxidation or burnt contacts that will need to be cleaned.

The Chevrolet Lanos fuel pump relay, where the control and controlled part (contact group) is located, as well as the fuses, is located in the mounting block of the engine compartment - in the right front corner.

To check the serviceability of the K9 relay, you will need instruments such as a multimeter or test light, a probe and a piece of wire. However, if the fuel pump is not working, first of all, it is recommended to check the serviceability of fuses F17 and F16, typical for Chevrolet Lanos. How to check the fuel pump relay is a frequently asked question, and the answer is quite simple - you just need to use one of the methods below.

First, you will need to remove the device from the mounting block and replace it with a working type, for example, relay K7 (for power windows). Turning on the fuel pump with an alternative relay indicates a faulty relay. If it does not turn on, we check the power and control circuits of the electrical device.
If there is no spare working relay, a similar method above to check the serviceability of the device is to install a jumper (a piece of wire, a paper clip) between contacts 30 and 87, which will close them when the ignition is on.
You can determine whether the device needs to be replaced by measuring the voltage between pin 86 and ground (minus). When the ignition is on, it should be equal to 12 V. We also check the voltage between pin 30 and ground. It is equal to the on-board network voltage. Its absence indicates a break in the wires between the contacts and ground. Otherwise, you need to connect the probe between pin 85 of the relay harness block and the positive terminal of the battery. If the probe lamp does not light up when the ignition is turned on, this indicates a malfunction of the controller or a broken wire. If the lamp comes on, it indicates the need to replace the electrical device.
Also, using a tester in ohmmeter mode between pin 85 and the vehicle ground, you can measure the resistance, which if the circuit is working properly should be 1 ohm.

Car enthusiasts who are interested in this model can find out how much the new Chevrolet Lanos costs on various Internet sites. The price of a new sedan varies from 250 thousand rubles. and higher depending on the configuration: basic S, medium SE and maximum SX.
