Heated seats VAZ 2114: considering options

The option of heated seats on domestic cars is no longer new. This feature should be present on every machine. With the onset of the first frosts, more and more VAZ owners are wondering why the heating does not work on the fourteenth. This is especially true for those whose cars are parked on the street.

Concerns from the northern countries were the first to install heated seats on manufactured cars. Initially, the option appeared on expensive cars, and later this will not surprise anyone on domestic vehicles.

Naturally, those who have already tried this option have only positive things to say about it.

Now we will look at the reasons why the seat heating system on a VAZ-2114 may not work. The information contained in the article will be partially useful to car owners of other cars, because the operating principle of the heaters is similar.

Let us immediately draw your attention to the fact that the process of troubleshooting is quite troublesome and will require you to have experience in carrying out repair work on the vehicle’s electrical network and the availability of certain devices.

How to repair heated seats?
It is absolutely clear to all of us that not every owner of a heated car has the time and desire to troubleshoot problems. Many, faced with this problem, simply let it take its course, and with the onset of cold weather, they scold themselves for the lack of desire to fix the breakdown in a timely manner. It's good if the car is still relatively new. Then we just need to take it to a service center under warranty, where everything will be quickly fixed. What to do if the car ages?

Or is heating simply not provided for your car, but was installed as an addition by a person long forgotten by you? In this case, it is enough to find an understanding electrician. Perhaps it will be your neighbor, relative, or a specialist at one of the service stations.

Anyone who understands this matter will be able to quickly identify and fix the problem, while charging a relatively small fee.

Let's look at the main reasons for this breakdown.

Health issue

Today, medical professionals are still actively arguing about the harm of heating seats inside cars. Some believe that heating is harmful to men's health. Others, on the contrary, consider this a normal and even useful addition to the car.

The decision is yours in any case. But we recommend not to get carried away with high temperatures. Just warm up the seat a little before you hit the road. And then turn off the system.

How to make built-in heated seats with your own hands?

Installing a seat heating system
First, you need to purchase the so-called backbone of the entire structure - heating elements. Why buy and not make it yourself? The issue is your safety. Since the elements are built-in, and any inaccuracy in independent work cannot be identified and eliminated in a very short safe period of time, it is better and more reliable to use ready-made elements. Their selection is quite large. We will focus on domestic (Russia), the quality of products of which is not inferior to reliable Germans, and the price is much more pleasant.

Included in this set you will find an electronic temperature controller and overheat protection.

The heating element in Emel is represented by reinforced cable or carbon fiber.

Additionally you will need:

Screwdriver Set,
wrenches for disassembling the chair,
plastic clamps,
scissors,
knife with replaceable blades,
insulating tape,
multimeter,
heat shrink tubes,
pliers, marker,
soldering iron,
double-sided tape (you can use glue 88),
stranded wire 2.5 mm sq. cross section - for wiring.

First, decide on all the control buttons and their fastenings, so that if necessary (suddenly they don’t fit in their regular place), purchase the ones that are suitable for this car.

Now we can get down to business.

Disassemble the seats: start with the headrest, then remove the plastic elements, then the seat upholstery, making room for laying heating mats. To remove the “back” trim, remove the plastic bushings for the headrests.

Place the sheet with heating elements on the seat foam, marking its dimensional contours with a marker. Following the marked lines, stick on strips of double-sided tape or use glue 88. If there is a temperature sensor, also install it on the foam rubber. Glue (attach) heating mats to the designated area on the seats

Here you should pay special attention to the location of the wires. Don’t forget that they should be on the right on the driver’s seat, and on the left on the passenger seat

Remove the power wires.

Install the “original” skin on the supplemented foam base, using plastic clamps in the required places. Also return all plastic elements, headrests to their original position and install the seats in their original places. The wiring should be laid in the locations where the power connections and controls are located.

A very important point: the wires going to the heating mats from the regulators cannot be laid under tension; leave such a margin that you can easily move the chair away if necessary.

It's time to connect the heating elements. The instructions included with the installation kit should help you with this issue. If it is not an assistant for you in connecting the unit to the on-board network, it would be better and more correct to turn to professionals for help

If you are confident in the correctness of your actions and are ready to try to figure out this stage yourself, we recommend that you pay attention to certain recommendations:

It is necessary to detect the power (12V), ignition and backlight circuits using a multimeter.
Connect the positive wire of the thermal relay to the ignition switch connector, where power appears only after turning the key.
Connect the power wire to the positive terminal of the battery through a fuse.
Connect the negative wire to ground, and the button backlight wire to the cigarette lighter contacts.
All connections, of course, must be soldered and insulated. Then you can check the system.

An important point: a correctly assembled system will only work when the ignition is turned on. Otherwise, you risk not starting the car someday.

Only one question remains unclear: what to do with the rear sofa and its heating? For those who constantly travel with their family in a car, this is a very important point. But there is nothing complicated here either: installation and connection of the rear seat heating system is similar to that described above. The only difference is that for one sofa you will need two sets of heating elements.

Dismantling works

To install heating elements, you first need to carry out a dismantling procedure. It includes the following activities.

Unscrew the plastic fasteners that connect the seats to the body of your car.
Remove the skids. Two pieces are located in front, and two more are located in the back.
Remove the chairs from the interior, otherwise it will be extremely uncomfortable to work.
Separate the back from the chair. To do this, there are bolts on the sides, which can be removed with a 10 mm wrench.
On the back there is a plug for the headrests, which can be removed.
The upholstery is removed from the hooks below. To do this, the hooks are slightly unbent.
Now you can completely remove all the trim.
Carry out a similar procedure with the second seat if you plan to install heating on it too.

While you are installing the heating, throw the upholstery into the washing machine. This will not harm her, and the interior will look newer and nicer.

Installation of heating elements

Many people forget about the need to securely fix the elements responsible for heating the seats. As a result, over time they can shift, thereby disrupting the performance of the system.

To avoid such situations, experts advise sewing heating elements directly to the inside of the upholstery. Although today some car owners prefer another option, which uses double-sided tape. The elements are held on it quite reliably, and the tape is attached to the foam rubber itself.

Connection process

Regardless of the chosen fixation method, reverse assembly looks the same for all options. This is the most difficult stage, so strictly adhere to the specified sequence of operations.

Pull the covering back onto the back, where the heating was already fixed. Using a mallet, the plugs are driven into place. We are talking about plugs for headrests. Next, the fabric is stretched. The front one is pushed through the hole, and the back one is straightened down. The fabric from the front is draped over the hooks and then stretched

Just watch the degree of tension so that the fabric does not tear. Now you can put the rear trim element on the hooks. The next step is to insert the wire into the front and tension the sheathing. If you plan to change the foam rubber, cut out the new elements in strict accordance with the dimensions of the old material. Pay attention to the areas where the spring contacts the body and seat ties. To avoid squeaks, use pieces from the washer tube, or simply wrap several layers of electrical tape. Heating for the lower part of a car seat is often mounted using double-sided tape or sewn to the trim on the inside.

You can use plastic clamps or wire brackets, which will prevent the heating elements from moving from their installation locations. After this, the plastic fasteners are tightened. Connect the backrest and seat. A wire is pulled through the hole in the frame and the foam rubber, with which the heating will be connected to the on-board network. The wiring connection is carried out strictly according to the diagram. It is necessarily included with the set of heating elements, so you don’t have to look for anything additional. The standard location for installing heating on and off buttons is the area near the handbrake. Although you can place them as you wish. It’s not uncommon for car owners to take an alternative route, installing a standard heating system on top of the seats, after which they put car covers on top.

There is a modern and very simple solution - heated capes that can be put on in winter and removed during warm periods. Their disadvantage is that the wire runs freely, which can interfere with the driver. Plus the capes do not fit tightly to the chairs.

DIY seat heating installation

To work, you need to first prepare the following set of tools:

various screwdrivers and wrenches;
multimeter;
insulating tape;
felt-tip pen or marker;
soldering iron;
construction knife;
pliers;
glue;
clamps and heat-shrinkable tubes.

Once all the tools and materials are ready, you can start working. First you need to dismantle the chairs and place them in a convenient place. Then completely disassemble them, removing all plastic elements and casing. Place the heating fabric on the seat foam and use a felt-tip pen to make marks along the contour. Using glue, fix the heating fabric along the marks.

Then you need to remove all the power wires and put on the casing. Now the seats can be attached to their places in the car and the power connected. Ideally, connecting the heating elements to the on-board system should be done by an electrician.

But, in principle, you can try to do this work yourself:

Using a multimeter, you need to find the 12 V power supply, ignition and backlight circuits.
Connect the wire (+) of the thermal relay to the ignition switch.
Connect the power cable to the positive terminal of the battery.
Connect the negative wire to ground.
Solder all wire connections using a soldering iron and wrap with electrical tape.
Check the operation of the system.

Below is a diagram of connecting the heated seats of the VAZ 2114 for the Emelya kit.

Keep in mind that the circuit must be assembled in such a way that it only functions when the ignition is on. If you assemble it incorrectly, then forgetting to turn off the heated seats at night, in the morning you will find a completely discharged battery.
