1 red thick wire + to the battery to the positive terminal

2 black thick wire - to the battery at the negative terminal or to the car body

The EUR diagnostic LED was installed in the instrument panel

Since the production of the VAZ-2114, it has been planned to install additional control kits. These are such as power steering and electric power steering, but they are not included with the new car. So, every motorist would not refuse to have one of these systems to simplify driving.

Video about installing electric power steering on a VAZ family car

The video will tell you how to install electric power steering on a car, and also tell you about some of the nuances and subtleties of the process.

How to install power steering on a VAZ 2114

From its very production, the steering system of the VAZ 2114 car assumed the possibility of installing power steering using an installation kit.
This also applies to electric power steering or simply EUR. This modification will make it easier to turn the car and increase comfortable handling. This is especially true for drivers who drive in the city most of the time.

The main difference between power steering (power steering) and electric power steering is that the strength (efficiency) of the former directly depends on the speed of the engine. At high speeds, turning the steering wheel is too easy. This affects both ride feel and handling.

To overcome such problems, the power steering is not connected directly to the motor, but using a gain regulator. This is exactly the functionality that an electric amplifier has. The operation of the electric power steering is not characterized by a direct connection between effort and motor power, which allows it to be used as much as necessary in a specific situation.

For the VAZ 2114, a similar EUR is suitable as for the Lada Priora.

Additional advantages of using an electric booster instead of power steering:

• Less maintenance requirements (no need to monitor oil, connections).
• In cold weather there is no need to warm up, as when using power steering.
• Installing the EUR is much easier (no need to interfere with the engine compartment).
• High reliability.
• The only downside is the lower power, although on passenger cars like the VAZ 2114 this is not at all noticeable.

Disadvantages of power steering

Like any device, an amplifier has both pros and cons, and here everyone chooses based on their own preferences, tastes and goals. Many drivers list the following as flaws in the system:

• Power steering does not contribute to fuel economy, and power steering is not always effective;
• If we talk about power steering, then it is necessary to regularly check and replace the pump as needed, which is very unreliable.

The disadvantages end there. What can the professionals say? Initially, we were faced with the issue of steering equipment for the VAZ 2114. Often, owners of Samara-2 complain that at high speed, power steering creates a feeling of weightlessness in the steering wheel, which sometimes completely confuses the driver. Without power steering, you have to turn the steering wheel too often, and it does not satisfy the requirements of a technical aesthete. What to do?

The problem occurs because the amplifier is powered by the engine itself. To remove the flaw, you should connect the power steering not directly to the engine, but through a gain regulator. And here's another secret: you can install an amplifier with an electric drive function on your car; today such devices are quite common.

Installation instructions

When installing an electric power steering, it is necessary to take into account that it will be necessary to replace the steering column of the VAZ 2114 with an “electrically driven column”. To do this, let's start with the wiring. You will need to deal with the pads. There will be no need for any “twists”. There is a terminal in the block that we need to remove and insert into the block in the harness.

We insert the free terminal of the harness exactly into the place where the standard wire was. You don't need a special harness for this. Connect two 4 square wires to the battery. Don't forget to connect a 50A fuse. The “weak point” will connect to the tachometer, speed sensor, ground, K-line and wiring to the warning lamp. Don't forget to check the presence of speedometer and tachometer signals.

1. Remove the casing with switches and ignition switch.
2. Unscrew the bolt on the rail and remove it. We need to determine how much larger the “native” part is than our new one.
3. We install the shaft on the EUR. After this we attach the shaft itself in its place.
4. Setting up the wiring. We stretch two cables to the battery from the passenger compartment, preferably through the left wing. To conduct wiring you can:

• First remove the washer fluid reservoir.
• Take a solid wire and drag it through, trying to get to the hood.
• As soon as it appears near the hood, we attach our wires to it.

• We pull it out together with our wire.

1. We connect the EUR electronics. There is a red connector under the instrument panel with an orange wire in it. It is to this that you need to connect the electric amplifier.
2. Similar procedures must be done with the gray wire.
3. We connect the power ends. In the battery we connect the pink one is a plus, and the black one is a minus.

Heater fan replacement procedure

The first step is to remove the positive terminal from the car battery to turn off the power supply to the old motor. After this we perform the following steps:

• in the engine compartment of the car, remove the fan casing and unscrew the screws that hold the part in place;
• remove the air supply grille, which is secured with special bolts;
• remove the rubber seal located directly under the grille;
• remove the dashboard from the driver's seat and disconnect the wires connected to the motor;
• slightly move the motor together with the protective casing, removing it from the clamps and removing the non-working part;
• remove the fan from the casing;
• we connect to the car’s electrical network and mount a new motor, after which we reassemble in the reverse order;
• connect the terminal to the battery and check the functionality of the stove.

We strongly recommend choosing a new and original motor to ensure trouble-free operation for a long time. If you still buy a used part, be sure to check its technical condition, integrity of contacts, and operability.

As you can see, the procedure for installing a new heater motor on a VAZ-2115 car does not require a lot of time, special skills and knowledge. Therefore, it is absolutely not necessary to take such a minor problem to a car service center, where the cost of such repairs can be quite high. Just buy a new part and install it, following all the recommendations given in our instructions.

Adjusting the steering wheel position

If you don’t like the height and position of the steering wheel, then you will need to grind the edges of the shaft to the size you need or install gaskets between the plate and the body. It is worth remembering that the electric power steering is automatically switched off at speeds above 50 km/h, unlike the same power steering.

Installing electric power steering on your own is quite possible. You just have to remember that even for an experienced driver it will take a lot of time and effort. But for a lover of comfortable driving, the result will justify all costs and hopes.

Power steering (power steering) on ​​VAZs appeared only starting with the VAZ 2110, while owners of the VAZ 2109 can only be content with steering without power steering. Not everyone is ready to put up with this, so people independently install the power steering from the VAZ 2110 (2112) to the “nines”. In this case, we get not only less effort on the steering wheel, but also a rack with a lower gear ratio - 2.8 turns instead of 3.8, which contributes to faster steering.

Let's look at how you can do this yourself in this article. This article will consist of two parts, in the first part we will look at the installation of the power steering pump, in the second - the installation of the steering rack under the power steering.

Go. First, remove the generator with bracket:

The pulley for the generator belt needs a ripple pulley, as in the figure below, so if there is another one, then we change it to this one:

This is what the VAZ 2110 power steering pump looks like together with the bracket:

The bracket needs to be modified, namely, unscrew the engine mount, saw off the ears of its mounting, and also saw off the far right mount (it gets in the way). In the end it should look like this:

Next, instead of the generator, which we will install above, we install a power steering pump:

As you can see, the second bolt will need to be shorter.

Next, we install the generator bracket, in our example it was taken from Kalina, with a tensioner. This is what it looks like assembled with the generator:

The bracket is installed with 3 bolts in standard places:

Our generator is also from a VAZ 2110. To install it, you will have to cut the “TV” a little:

Next we install the generator and belt. You need a belt marked 6PK975 (or 970).

VAZ 2114 cars are supplied for sale with steering systems that allow the installation of a hydraulic or electric power steering wheel. The EUR is a unit used to ensure smoother and, importantly, comfortable driving by easily turning the steering wheel. You can learn more about how to install the EUR on a VAZ 2114 from this material.

Possible problems

Some drivers note that in a VAZ 2114 with a hydraulic booster, the control system becomes as if weightless. This can be confusing. When the gain is lost, the steering wheel has to be turned more often.

A fairly common problem caused by the fact that the hydraulic booster operates directly from the power unit. In order to correct the situation, the hydrach is connected not directly to the engine, but using a gain regulator. Another option is to use an amplifier with an electric drive function. Today, such a device is not difficult to find, and it costs relatively little.

Wiring

As for replacing the hydraulic booster with an electric booster, this is a more than possible option for improving the car. It is considered one of the simplest but most effective types of technical tuning. However, it is strongly not recommended to perform such operations yourself.

Choose specialized car services that specialize in technical modifications and tuning of the car. AvtoVAZ cars, which include the VAZ 2114, are beautiful because they are literally created for tuning. Many young drivers choose the “fourteenth” model as their first car. This is due to the wide possibilities for modification with minimal investment. This car lends itself perfectly to external tuning, and the current spare parts market makes it possible to improve the internal filling. This includes replacing the power steering with electric power steering.

The feasibility of installing EUR

Does it make sense to install power steering (power steering) or power steering on the “four”? In this case, it is impossible to give a universal answer, since it is unique for each motorist. Of course, with power steering or electric power steering, the process of turning the steering wheel will be easier, making driving more comfortable. But there is another side to the issue - firstly, the cost of the power steering or electric power steering kit, as well as the rather complicated installation of the system yourself. In general, it’s up to you to decide, but if you decide to install an electric booster on your car, we will help you with the installation.

Detailed Installation Guide

So, if you decide to install electric power steering on a VAZ 2114, then you need to take into account that you will also have to replace the steering column itself. In particular, instead of a standard device, you will need to install a column with an electric drive; accordingly, our repair process will begin with the wiring. You will need to deal with all the connectors and connectors, because you must do everything beautifully, without any twisting of the wires. The block has a special terminal that you will need to remove and then install it on the connector in the harness.

The free terminal of this connector is installed in the place where the standard wiring ran; no special harnesses or adapters are required for this. You only need to connect two 4 square cables to the battery. To ensure the safety of this section of the electrical circuit, it is additionally necessary to install a 50 ampere safety element.

Next, using the so-called weak current, that is, not a power wire, you need to connect to the following elements:

• tachometer, used to display the number of revolutions of the engine crankshaft;
• a speed sensor used to indicate the speed of the vehicle;
• mass, that is, the car body;
• diagnostic K-line;
• as well as to the control light (the author of the video about installing the unit at home is the sokur64 channel).

After completing these steps, you will need to diagnose the presence of a tachometer signal, as well as a speedometer.

If there are signals, then the further installation procedure is as follows:

1. The plastic casing on the steering column, where the switches are installed, as well as the ignition switch, is dismantled. To do this, you need to unscrew all the bolts that secure the protective cover.
2. Then you need to unscrew the screw installed on the rail and dismantle it. At this point, you will need to determine how much the size of the assembly installed during production differs from the size that will be used.
3. At the next stage, the shaft is mounted directly on the electric amplifier. After this, the shaft itself must be fixed at the installation site.
4. The next step is to configure the electrical circuit. It is necessary to run two wires from the vehicle interior to the battery; alternatively, this can be done through the left fender. To do this, you must first dismantle the expansion tank of the washer system, and then, using the hardest and thickest wire, stretch it. You need to try to get to the engine compartment.
5. When the end of the wire appears in the engine compartment, you need to attach the wiring to it. Next, both wires will need to be pulled out along with the wire itself.
6. Having completed all these steps, we proceed to one of the main steps - connecting the electric amplifier electronics. Under the dashboard in the “four” there is a special red block, inside of which there is an orange cable. The EUR contact itself must be connected to this wire. The same actions are performed with the gray wire.
7. Then the power ends are connected. Pink and black wires are connected to the battery, pink to the positive terminal, black to the negative. At this point, the installation process can be considered complete. Check the functionality of the installed system and, if necessary, adjust the device.

Why does the heater motor fail?

Is it possible to do without replacing this part and try to restore its functionality on your own? Theoretically, yes. But in reality this happens quite rarely, since setting up a fan is a difficult task even for experienced craftsmen.

The main reasons why the stove motor malfunctions are:

• fuse burnt out. This breakdown is not difficult to perform, since the safety element also protects the cigarette lighter, glove compartment light and headlight washer from short circuits. Of course, if it malfunctions, this equipment will also not work;
• failure of the fan winding;
• problems with the ignition relay. If warm air begins to enter the cabin only after the engine has warmed up, then the problem is in this part;
• failure of the resistor, which allows you to configure the heater to operate in several modes;
• The contacts on the motor block are oxidized.

As we have already found out, in case of any fan failure, it is best to replace it - this will save you money and time, and will also ensure an optimal climate in the car interior.

The nuances of adjusting the steering wheel position

If you are not satisfied with the position of the steering wheel or its height, this can be corrected by adjustment. To do this, it is necessary to grind the edges of the industrial shaft to the required dimensions or install gaskets between the device body and the plate. When making adjustments, you must remember that the EUR itself is automatically turned off when the vehicle speed exceeds 50 km/h.

Price issue

The cost of electric power steering for a VAZ 2114 car may vary, depending on the store where it is purchased, as well as the region of the country. On average, the price for a complete system set varies around 22-24 thousand rubles. On the Internet, you can search for stores where the EUR kit is sold on promotions - with a discount from the seller, you can purchase the unit for 20 thousand rubles.

Functionality check

After you have connected all the elements of the system, you need to install the steering wheel and check the functionality of the mechanism. If you are satisfied with the work, then you need to assemble all the elements in the reverse order. After this, start the engine and try turning the steering wheel at low speed.

In this case, the electric drive should work to help you turn the wheels in the desired direction. Then you need to accelerate the car. At high speed, the electric power steering on the VAZ-2114 should not work. Otherwise, you most likely made a mistake when connecting the wires coming from the sensors.
