Show the scheme for seat heating VAZ 2114. Install seat heating
With the advent of cold weather, drivers of cars, especially those that are stored outside garages, are interested in why seat heating on the VAZ 2114 and 2115 does not work. Some time ago, drivers of even prestigious cars did not dream of such an option. The first to start installing heating systems were manufacturers from the Nordic countries.
Initially, they appeared on prestigious car brands, and today it can already be found on budget models of cars. Those owners who have tried this option in business speak very positively about it.
Why the seat heating does not work on the VAZ 2114 and 2115 consider in this article. It will help owners of other car brands to some extent, since the principle of operation and connection are largely similar. I would like to warn you that finding and fixing problems with this function is a very troublesome and time-consuming task, and you will also need experience in repairing electrical equipment and the availability of measuring instruments.
Why do you need heated seats?
This is important and necessary thing in your car, especially when it's bitterly cold outside. If you very often get into the passenger compartment of a car that long time stood in the cold, it is not only unpleasant, but also dangerous to the health of the driver and passengers. But at the same time, overheating of the seats also promises problems for those sitting on them, and in some cases for the car.
You can find a lot of information, both about the benefits of heating, and about its inexpediency. Let's try to understand this information together. Long trips with heaters on can have a negative impact on men and women. Therefore, you need to be able to use this function correctly and in a timely manner. Landing in the salon with leather trim seats in winter time, can cause problems for drivers of both sexes, in the form of cystitis or prostatitis.
There are certain, developed and time-tested rules for using heating:
- The seats must not be allowed to overheat;
- In the cold interior of the car, the heating system should be turned on, but for some time it does not sit on them;
- After warming up, the system must be turned off, further heating must be carried out by the heater;
- You do not need to stay in the salon in warm clothes for a long time.
How it works?
The main element of such a system is a heating element powered by the on-board network. It is placed in an elastic panel and built into the cushion and backrests of the front seats. Such systems are of two types, one of which is built into the pillows, and the second is made in the form of capes on the seats. Despite these differences, the principle of their work is almost the same.
The heating elements are covered with a special coating to avoid direct contact with the upholstery, which makes it easy to copy the contours of the pillows. There are designs with one heating element and with two, but of different power. The heaters are connected to the on-board network of the machine through the control unit. In some models, it is possible to set the desired temperature.
A temperature sensor is installed in the heater installation area, it controls the heating temperature and, upon reaching the desired value, turns off the power. The system may also have another function that will automatically maintain the heating parameters set by the driver for a long time. Another type of heater can be controlled using the built-in timer.
Also, built-in devices with two heating elements can support the fast warm-up function, after which they automatically switch to lower power and lower heating. In some models, there may be several such modes, they can be selected individually for each seat.
Problems with heated seats
Like all electrical circuits, heating devices have a fuse, and on this model there are two. One is installed in the mounting block, it is F16, and the second is suspended under the instrument panel. If the control lights do not light up when the heating button is pressed, the problem must be sought in the fuses.
The direct activation of the heating elements is carried out by an electromagnetic relay, it is also located under the instrument panel. After it is triggered, you should check with a voltmeter for the presence of voltage at terminal number 87. If operation does not occur, check the relay winding with an ohmmeter, these are conclusions with numbers 86 and 86, or installing a new one.
Next, they check the presence of power, with the switch on, at the connectors under the seats, for this they are disconnected from the wires of the heaters. The black wire is connected to the mass of the car, and the second should have 12 volts of the on-board network. At the same time, the resistance of the windings of the heating element is checked with an ohmmeter. Most of the time the problems are there. There is a break or burning of the windings and supply wires.
In some cases, they can be restored, but for this you have to remove and disassemble the seat cushions. Of course, this is not all possible reasons why the seat heating does not work on the VAZ 2114 and 2115. The article gives a direction for finding possible problems in the heating systems, and then you need the experience and skill of the driver with the electrical equipment of the car.
Seat heating on front-wheel drive VAZs appeared only in the luxury versions of the VAZ 2113 - 2115, and VAZ 2110. In the standard configuration on the VAZ 2109 and its varieties (-08, -099), this option is not available, although it would not really interfere with drivers living on areas with cold climates. When there is a “minus” outside the window, it is much more pleasant to sit in a warm chair, and not sit and freeze while waiting for the cabin to warm up.
For refinement, we need regular heating elements for heating the front seats VAZ 2113-2115, which must be installed in the seats. To do this, you need to remove the fabric upholstery of the seats, and install the heating elements under it. For reliability, they can be sewn. At the same time, you can restore the chairs a bit - replace the sagging foam rubber, wash the upholstery.
Now we connect the electrical part. The main power "plus" can be taken from the cigarette lighter. As a protective measure, we connect it through a relay that will turn on when the ignition is turned on to prevent the heating from working when the car is turned off (for forgetful ones). Illumination of buttons - "plus" dimensions (for example, cigarette lighter illumination).
The buttons for turning on the seat heating can be placed on the casing of the floor tunnel between the seats.
For those who do not want to mess with the disassembly of the seats, there is an easier option. On sale there are special kits that are simply placed on the surface of the seats and fixed to them. There were good reviews about the Emelya front seat heating kits. They can be connected simply to the cigarette lighter.
Just do not place them under the seat covers, they are designed to be placed on top of them. For those who do not recognize the presence of dangling wires in the cabin, you can connect such heating according to the scheme above for built-in heating.
In this article, we will look at how you can make a heated seat for a VAZ 2115 car with your own hands. The reasons that prompted you to make seat heating may be different. For example, they didn’t want to give money to an electrician to save money, and also wanted to do everything themselves. The reasons may be these two at once. Therefore, we briefly describe the whole process.
We will need the following materials. A small twist of wires that is connected to a light bulb is called a dialer, shown in Figure 1.
In addition, we need two more buttons, which we install between the seats on the right and left. The buttons that are responsible for turning on the seat heating are shown in Figure 2.
Electronic wiring is quite laborious and requires certain skills. And the difficulties in installing the electric train, you can turn to specialists who will help you connect the wires to the heating buttons. And for those who want to independently connect the seat heating wires, there is a diagram that is shown in Figure 3.
You will also need two relays, which are shown in the photo with the image of the buttons, located not far from the buttons under the panel.
A detailed wiring diagram for the wire bundle button is shown in the following figure.
When connecting this equipment by trial and error, it must be taken into account that two fuses located under the hood of the machine may burn out. But globally, of course, nothing will burn, since there are no serious elements that can be damaged by an inept specialist. Therefore, you can be calm, I connect these schemes and, accordingly, bars.
When connecting, it is necessary to use a dialer that we make in advance from two wires and a light bulb, which will greatly facilitate the understanding of which wire to connect to. To connect the seat heater, you need to find the plus and minus. The easiest way is the pluses from the cigarette lighter minus from the body.
