Installing heated seats on Lada Granta - instructions, 2 connection options

Heated seats, two connection options

Not all Granta trim levels have heated seats.
In Russia, this element is extremely necessary, because getting into a cold car is quite unpleasant and is fraught with health problems. When buying, you don’t always worry about the little things and want to buy a car at a lower price. But then people like to add the missing functions themselves. Now we’ll look at how you can make seat heating without the help of specialists, with your own hands. First, we will need to buy a heating pad, a Kalinovskaya one or one from Granta will do. The price for the original heating is 1100 rubles. In the kit you will find:

1. wires, fuses, buttons
2. warmers themselves for two chairs
3. connection diagram

All this stuff looks like this:

If you wish, you can first remove the chairs. This will be more convenient, but leaving them in place will allow you to install the structural elements.

The installation process begins with unscrewing the plastic covers on both sides.

They need to be removed to gain access to the bolts connecting the chair and the backrest.

We unscrew these bolts and separate the seat.

Next, remove the seat covering material and fold it up. We do the same with the back.

We take our heating pads from the kit and slip them under the material.

Carefully place the casing in place, making sure there are no folds. After assembling the seat, you need to connect the black wires from the two heaters, and connect the white one to the power supply.

The power supply is located under the shift lever housing. Having unfastened it, we pass our wires from the right and left seats through the central channel. Don't forget to install the fuse, it is included in the kit.

Having completed all the steps, all that remains is to display the on and off buttons on the panel with cup holders.

The process of installing heating on Granta Liftback can be significantly simplified by using universal heating capes. In this case, there is no need to disassemble the floor of the car. You just need to throw them on the seat and plug them into the cigarette lighter socket.

Types of heating elements

The domestic market today offers a huge selection of various devices and devices to increase the comfort of machine control. And seat heating in this case is no exception. First, let's look at the types of systems.

Cases and capes

The heated seat cover can be made in the form of a cover. It should be noted that this version of heating systems is characterized by ease of installation, as well as an affordable price. Installing heated seats in this case comes down to installing a cape and connecting it to the cigarette lighter.

It should be noted that a heated cape for a car is an option that has many disadvantages:

• wires that will constantly get tangled;
• too low level of electrical protection and fire safety;
• heating of the entire area of ​​the cape will be uneven;
• car covers do not always fit successfully into the interior of the car;
• heated rear seats will not be possible.

It should also be noted that installing seat heating in this case requires a free cigarette lighter socket. And since today this socket is universal, since DVRs, radar detectors, GPS navigators and other devices can be powered from it, installing the system will be problematic. You can use a splitter, but due to the large number of consumers, the safety elements may also fail.

Built-in models

If you decide to install heated seats in your car and want to use a built-in type, then you need to take into account that this method is difficult to install. However, you can still install an embedded system yourself.

It should also be noted that built-in heated front seats have certain advantages:

• you can equip not only the front but also the rear seats with a heater;
• such a system should be installed under the seat trim, and the wiring should be laid under the interior upholstery;
• to activate the system, use the seat heating button, and the system itself is connected to the on-board network, accordingly, the cigarette lighter socket will be free;
• the use of such a system will not affect the interior of the cabin.

Composition of a seat heating kit and how to install heaters on Granta with your own hands

Preparation for installation of heating elements

Before connecting the heated seats on the Grant, you need to secure the heaters under the upholstery of the seats. Of course, it is more convenient to do this on dismantled “seats”, previously disassembled into two parts: the back and the support. Creating acceptable conditions for installing heating elements is the goal of the preparatory stage. By the way, when determining the reasons for the knocking of hydraulic compensators, there is a slightly different logic.

Preliminary activities are carried out according to the following scenario:

• Disconnect the power supply to the seat belt sensor located under the seat. In many trim levels, this option is available only to the driver.
• Using an E10 head mounted on the knob, unscrew the four bolts connecting the base of the seat frame to the body and remove the seat. For ease of access to fastening elements, move the seat to the farthest or closest position. Similarly, remove and pull out the second front “seat” from the passenger compartment.

• Remove the backrest angle adjustment knob by prying it off with two flat-head screwdrivers.
• At the junction of the backrest and seat, remove the plastic covers on the left and right sides by unscrewing one screw each.
• Unscrew 2 bolts on each side securing the backrest frame to the metal base.
• Detach the backrest from the seat.
• Repeat steps 3-6 for the second chair.

Factory covers are attached to the frame with four clips. On the reverse side, the fixing elements are clamped with wires. Having untwisted the latter, we tighten the fabric. Before removing the backrest cover, disconnect the plastic lock at the bottom of the structure. When assembling, it is advisable to replace the wire with plastic clamps.

Installation of heaters

The purpose of preliminary positioning is to achieve such an arrangement of the heaters that the wires exit into the joint of the backrest and seat. You won't be able to play with the longitudinal base - the standard kit is designed strictly according to the dimensions of the depressions. After removing the protective tape, glue the element to the frame. If necessary, the foam is trimmed to allow the wire to exit unnoticed.

The best built-in systems

To choose high-quality seat heating, you should pay attention to the following brands:

There are no permanent systems for child seats, since such installation of heated seats will be fraught with many difficulties. However, if necessary, you can make a heater for any type of seat yourself.

Power supply or how to connect the heated front seats on the Lada Granta correctly

The cost of installation work at an unofficial service station is at least 2,500 rubles. For this money, already purchased heating elements will be installed in the car seat and the circuit will be connected according to the manual. All that remains is to make an anti-freeze product according to a home recipe and hit the road. This is for the quick ones. Painful owners will probably not like the electrical part of the integration.

Disadvantages of the standard kit

The instructions indicate how to install heated seats on the Grant and connect it to the on-board network. According to what is written, the electrics connect and function like this:

• The permanent plus is taken from the hazard warning button.
• The ground is connected to the bracket for fastening the standard wires of the negative pole.
• The standard fuse is replaced with a more powerful one.
• The heating is turned on/off using the buttons directly.

Only one function is correctly implemented - turning off the heating when the ignition is turned off. Otherwise, the connection scheme is not entirely successful:

1. The positive wire that goes to the emergency light is thin and will probably work at the limit.
2. The contact group of buttons operates in a dangerous mode, since it is not intended for power loads.

For your information. The kit offers simplified buttons for installation - they do not have a power indicator in the form of a yellow lamp (as on the rear window heating control).

Competent connection diagram

An unfortunate result of the standard connection algorithm is a melted fuse. Such a reaction indicates that the circuit is operating at its limit. An alternative scheme for connecting heated seats will help to avoid this. It involves the use of two four-pin relays and powering them from switch K4, which supplies the output “+” after turning on the ignition.

Additional items

It is advisable to carry out installation work after purchasing an additional mounting block of reduced size. You will also need regular contacts for connecting two relays and two Lyra contact elements linking a 10A fuse. We also add additional wires with a cross-section of 4 and 1.5 mm2 to the shopping list.

Connection

Rear seat heating connection diagram:

It is better to take contact “B” from a protected high-current circuit with a fuse. Contacts “A” and “C” can be found in the ERA-GLONASS lighting lamp, in the ISO radio or cigarette lighter connector. Before starting the connection, do not forget to disconnect the negative terminal of the battery.

Installation and connection of heated rear seats on a Lada Vesta on video in several episodes:

Let us remind you that we previously told you how to connect heated windows/mirrors to an additional alarm channel on Lada Vesta and XRAY, as well as how to turn on the heated windshield through a separate button.

Grant seat heating installation

In the first part

In this article, I described the introduction of a set of heating elements from the Alamara into the Granta seats. In the second part I will try to describe how we can connect them to the car’s on-board network. Let's figure out the connection together. Many connect heating through one or two relays. I had a small diagram included with the wiring harness for connecting the heating. There were no relays marked on it, just as there were no relays in the wiring itself. And the power was taken from the alarm connector. It was also indicated there that it is necessary to replace the original 5 A fuse of this circuit with a more powerful one - 10 A. Let's check if such a connection is safe: After installing the heaters in the chairs, I connected them to a powerful 12 V power supply to check their functionality . At the same time, I decided to understand the connection in more detail and make sure that this circuit is reliable and correct. I connected an ammeter to the circuit and measured the amperage under load. You can see the results in the photo:

As you can see above, with a heating power supply load for one seat, the current consumption is in the range of 2.4-2.5 A. We look at the maximum load current of our heating button - it is equal to 5A (Stamped on the button itself). That is, the current reserve for our button is quite large. The conclusion that follows is that the buttons can be freely used without a relay.

Next, you need to find out the total amperage of heating consumption on two chairs. Turn it on and measure it.

We see that the amperage did not go beyond 5 A. It follows that the recommendation in the wiring diagram is correct. That is, you can take the plus (with the ignition on) from the alarm connector and increase the fuse rating of this circuit by 5A. But I decided not to pull the wires so far, and took the plus from the connector for adjusting the heater blowing speed. There is a wire with a thicker cross-section than on the emergency gang, and there is no need to pull it through the entire panel.

Now after the theoretical part, let's get down to business:

It is most convenient to connect the wiring with the seats removed. First of all, we need to remove the plastic floor tunnel. It is secured with five self-tapping screws. To begin, unscrew two screws on the right and left of the tunnel. Their location can be seen from the photographs:

By choosing the Classic package, the user gives up the pleasant warm options and sound system presented in the next Comfort equipment level. The message is cost-effective: for an additional 50,000 rubles you can equip your Lada Granta with a higher-quality audio system, and spend the remaining money on a set of standard seat heating. We take care of the installation work - we will reduce costs and properly power the circuit.

For finance

How much does the whole remodel cost?

1. I bought 2 seats from a car dealer for 7,500 rubles.
2. Armrest – 2150 rubles.
3. Covers – 2000 rubles.

The total cost was 11,650 rubles for all my re-equipment. The most budget option, since I didn’t take original covers, but universal ones. They don't fit the pattern a little, but it's not noticeable. Original covers cost 6,500 rubles. To be honest, I regretted spending money on them.

Whether you want to make such a modification to the seats or not, decide for yourself. I was confused, I liked it - the Lada Granta became completely different. It became more comfortable in it.

Homemade engine heater with pump

When making a homemade internal combustion engine heater with a pump, you need to take into account the following nuances:

1. The heater and pump can be installed anywhere in the cooling system. The pump creates the necessary pressure, allowing the consumable to circulate forcibly.
2. To ensure good heating of the soldering area, it is better to use gas or spot welding.

What will be needed for production?

To create such a heater, you will need:

• a piece of thick-walled pipe 80 mm long;
• pump (in the example a pump from Gazelle is used);
• two 20 mm hoses;
• metal plate;
• nichrome thread.

Manufacturing stages

Step-by-step assembly instructions:

1. First, the thick-walled tube is processed. It is necessary to ensure that its appearance and diameter correspond to the required dimensions.
2. Two disks are cut from a metal plate. The dimensions of these components must correspond to the diameters of the pipes.
3. One additional plate is welded or soldered to each disk. This will ensure better heat transfer and efficient heating.
4. To create a heat exchanger, you can process the seams of the device with a soldering iron or welding equipment. At this stage, it is important to make sure there is a good seal and no gaps to prevent liquid leakage in the future. High-quality electrical insulation can be achieved by using asbestos sheets.
5. The nichrome spiral is attached to a sheet of paronite; the fixation is carried out in special holes. To ensure better performance, the resistance of the spiral should be in the range of 2.5-4 Ohms.
6. Heating elements must be laid in spirals downwards. To ensure maximum insulation, the device must be wrapped in thermal insulation material, for example, foam film.

Installing a homemade heater

Installation of the heating system is performed as follows:

1. The lower hose for supplying antifreeze to the stove is cut.
2. A heat exchanger equipped with a water pump is inserted into the gap formed. The pump is necessary to circulate the refrigerant through a small circle of the cooling system.
3. The heating system is connected to the wiring using a separate toggle switch with an executive relay. If the device turns off over time, the circuit must be equipped with an additional relay.
4. All contact components are connected.
5. The heater installed in the car, all hoses and pipes are visually checked for lack of sealing. If any area is suspected, it is recommended to immediately replace the clamps. The initial start-up of the heater is carried out and the operation of the system is checked.

Video: DIY installation of a heater with a pump

The Do-It-Yourself Auto Service channel published a video showing the process of installing an engine heater with a pump yourself.

So, in order to connect the heated front seats on the Grant, you need to find out the number of the output plus of relay K4, which appears after turning on the ignition. This can be either the 87th or the 30th contact.

Usually this is contact element No. 30, but it doesn’t hurt to make sure once again. We remove the relay and diagnose. The test is carried out by connecting a 12V lamp to the 30th contact of the mounting block and ground. After activating the ignition, the lamp should light up.

Convenient alternative: replacing the car seat

The most convenient - but also the most expensive - option for installing a seat heater in a car is to replace the entire seat with an analog one, but with a heating function.

Suitable car seats with heated seats can be purchased at a salvage yard. Depending on the time of year, a set of two seats will cost from 5 to 30, 60 thousand rubles or even more: baza.drom.ru

The following rule also applies here: if the seat is fitted with a side airbag, removal and installation must only be carried out by a specialist. The price is usually negotiable.
