Replacing the heater resistor VAZ 2112 16 valves

The heater rheostat (resistor) is responsible for changing the speed of the hot air flow through manual control inside the car. If this part fails, the heater fan operates only in the 4th extreme position. Constant operation of the electric motor at high speed leads to inconvenience in using the stove and rapid wear of the fan.

Heater resistor

Self-service and repair of VAZ cars is a common occurrence for many car owners.
Periodic failure of some parts of the heating system is common in the “tenth” family. The most common problem is a broken heater rheostat. In the article we will look at where this element is located and how to replace it.

The controller receives information from:

– sensor 6

air temperature in the cabin (a small fan is built into the sensor);

– micromotor gear shaft position sensor 9

heater damper drive, i.e. information about the position of the heater damper.

Based on the information received and the set air temperature, the controller controls the position of the heater damper, sending appropriate signals to the damper drive micromotor.

If the fan operating mode switch handle is in position A, then the controller also controls the fan speed depending on the difference in the air temperature in the cabin and the temperature set point.

A valve is used to quickly warm up the air in the cabin. 8

. When the valve is turned on, the flow of outside air into the cabin is blocked and only cabin air circulates through the heater.

The vehicle is equipped with a heater fan electric motor of type 45.3730, excited by permanent magnets.

Additional resistor 2

serves to select the fan operating mode. It has two coils with a resistance of 0.23 and 0.82 Ohms. When you turn the heater fan switch knob on the heater control panel, you can turn on either both spirals (1st speed), or a spiral with a resistance of 0.23 Ohm (2nd speed), or turn on the engine directly without a resistor (3rd speed).

Location of the heater resistor on VAZ 2110-2112

To replace a burnt-out resistor yourself, it is enough to know where the part is located, as well as to have a minimum set of tools on hand. Regardless of what year the car is, the location of the rheostat remains the same - in the engine compartment, near the heater fan. During a visual inspection, this resistance block cannot be seen, because it is hidden by a plastic cover (“frill”).

For an accurate understanding of where the part is located, here is a photo.

In the process of restoring proper operation of the stove, it was decided to replace the old electric motor on bushings with a more reliable and less noisy one from LUZAR on bearings. and also the idea will be implemented to make on your heater: - 3 speeds with a heater fan switch from the VAZ 2109.

ELECTRIC FANS LUZAR

(electric motors assembled with an impeller) have a number of advantages: - The profile of the fan blades has been modernized - increasing the speed and volume of air; — A balanced impeller (for the first time on the Russian market) allows to reduce the noise level by 25-50%; — Two floating bearings reduce friction and eliminate shaft runout; — The motor winding uses single-core copper wire, insulated with a special varnish to prevent damage to the winding.

Specifications:

— Design designation ME255 — Rated voltage, V 12 — Rated power, W 20 — Maximum current, A 5.0 — Rated rotation speed, min -1 3000 — Weight, kg 0.85

Resistor VAZ 2109

An additional resistor connected to the power circuit of the electric motor of the interior heater on a VAZ 2109 is necessary to regulate engine speed by changing the resistance in the circuit. As a rule, this resistor consists of two resistances 0.23 and 0.82 Ohms.

The heater is turned on using a handle located in the cabin on the heater control panel. This switch has three modes - the first mode includes both resistors in the circuit and the engine runs at low speeds, at the second speed only a resistor with a resistance of 0.23 Ohms is included in the circuit, and the third mode does not include the inclusion of a resistance in the circuit, which means the engine runs at its intended speed. rpm

Reasons for rheostat failure

Despite the simplicity of the design of the heating system in VAZ cars of the “tenth” family, resistor malfunctions often occur. Let's consider several main reasons for the breakdown of this part:

short circuit in the circuit (more precisely, low resistance of the windings in the fan motor);
tight movement of the stove impeller caused by contamination and lack of lubrication on the mechanisms. The jamming of the stove causes the resistor to burn out;
Constant operation of the stove in the first position. It is worth periodically running the heater at high speeds.

Also, the cause of a resistor malfunction may lie in the poor quality of the part. It is enough to install the factory version, and the problem will go away.

As a recommendation, we note that for normal operation of the heating system, it is necessary to periodically service the stove, change the cabin filter and prevent dirt and dry leaves from getting into the stove.

Functions and purpose of the resistor

A resistor is often used in many vehicle electrical circuits. Its main function is the control and distribution of the supplied current to the element of its consumption, in this case to the car’s stove.

In cars, the source of current is the battery, which generates the necessary electrical charge for the functioning of all electrical elements of the vehicle. The resistor, in turn, transforms the current into the required voltage limits for the uninterrupted operation of a particular part. If the current converter becomes unusable, then more voltage will be supplied to the stove than is required for its operation, and the interior heating system will not work. Also, high voltage can cause burnout of heater parts that operate on current.

Replacing a faulty resistance block

Because Apart from the body design, there are no differences in the mechanisms and main units between the VAZ 2110, 2111 and 2112; the instructions for replacing the heater rheostat are universal. You can repair a problem with the operation of the stove yourself if you have a couple of screwdrivers and several spanners.

The step-by-step process for replacing the rheostat looks like this:

Open the hood and unscrew the wipers.
Next, remove the plastic trim under the windshield (“jabot”).
Remove the chip with wires from the rheostat and remove it from its seat.

Important! Before starting work, you should make sure that the cause of the problem lies in the resistor. The test is easy: get to the part and connect the multimeter to the power wires, then turn on the ignition. Another sign of a problem is that the stove operates only in the 4th position.

Also, as a recommendation, we note that at the time of disassembling the plastic lining, you can clean the stove cavity. When driving in the autumn, dry leaves and dirt often get into the stove, which makes it difficult for the fan to rotate.

Principle of operation

The electrical circuit of the heater consists of:

electric motor with fan (the fan blows hot air into the cabin, onto the windows and according to adjustments);
power and speed selection buttons (on the classic VAZ 2101 - 2107, there are only two rotation speeds, on the VAZ 2108 - 2115 there are three speeds, on the VAZ 2110 - 2112 there are three speeds plus a ventilation mode);
a set of additional resistances to ensure the required rotation speed of the heater fan (step-down, tungsten, turn coils);
fuse and wiring;

Tips for using the stove

For several years of production of cars of the “tenth” VAZ family, engineers did not provide for the possibility of modifying the rheostat. The design with this part does not allow you to be 100% confident in the reliability of the heater. It is also worth noting that the location of the part is not the most convenient.

To ensure long-term operation of the resistor, we recommend following the following recommendations:

use the stove in different positions and do not allow long periods of operation in one mode;
If there are extraneous noises, creaks and whistles from the fan, it is recommended to stop its operation until the cause of the noise is eliminated.

Because The price of this part is low, and it often breaks down - we recommend carrying a spare with you in case of breakdown. We also note that in the absence of a spare part, the operation of the faulty heating element can be restored by resoldering the contacts. This method is temporary, so having instructions for replacement will not be superfluous.

Otherwise, the design of the heater in the “tenth” VAZ family is simple, so it rarely fails. The weak link in this design is the rheostat, but understanding how to replace it allows you not to think about a possible breakdown.

Electrical diagram of the stove and main faults

In the “nine”, the VAZ heating system operates using an electric drive. The instruction manual for the VAZ 2109 high panel shows an electrical diagram of the stove's operation. The interior heater connection diagram consists of:

fan motor;
the ignition switch, which turns on the stove;
operating mode switch;
additional resistor;
fuse mounting block (fuse F4 is responsible for the stove in the “nine”).

When the VAZ 2109 stove does not heat well in the cabin, there can be a lot of reasons for this.

Replacing the heater resistor VAZ 2112 16 valves

I welcome everyone who loves to make, fix and repair everything with their own hands. Mr.PykoJob will help you with advice, show you with an example, disassemble and assemble everything simply and easily!

With the onset of cold weather, a malfunction of the VAZ 2112 heater appeared. The airflow only worked at maximum speed. It immediately became obvious that the problem was in the resistor of the electric heater fan.

The problem is unpleasant, but easy to fix. In this article I will show you how to deal with it and fix it if you encounter the same problem.

To get the resistor, you need to remove the frill, disconnect the terminal and, by unscrewing one screw, remove the resistor itself.

Since I have an old-style resistor, the difficulty was that the spring-loaded contact was unsoldered. Therefore, we solder it back and check the operation.

After a successful test, we install everything in place.

While installing the resistor, the screw fell off because... it is located in an inconvenient place. For those RukoJobs like me, I came up with a little life hack to get the screw and not lose it again:

I attached a neodymium magnet to a screwdriver - in this way I took out the screw and simply and conveniently screwed it into place.

Work to replace the fan in the cabin

Replacing the heater motor of a VAZ 2110

The subsequent change of the heater motor will be done directly from inside the car:

Under the dashboard you need to find the block that goes to the electric motor. She disconnects. After this, you will need to unfasten the ground wiring of the electric motor. As a rule, it is pressed to the body by the front mounting nut of the heater. The trim and lining of the windshield frame are dismantled, and you cannot do without unscrewing the mounting screws. The right upholstery is removed from the interior heater, and the fastening nuts and screws should also be unscrewed. Heating hoses are disconnected

At this stage of work, extreme caution must be taken, since antifreeze residues may leak from these hoses and the heater radiator. To prevent the smell of coolant in the car interior, you need to lay a material that absorbs moisture well. The wiring is disconnected from the electric motor, from the micro-reducer, and also from the pneumatic valve. After these steps, remove the front housing with the stove casing

These elements are fixed with brackets and screws. It is worth noting that the engine and motor are located on the casing. The latches are removed, and the engine and motor are removed.

Recommendations for replacing the motor

Replacing the heater motor of a VAZ 2110

You can disassemble the electric motor yourself only to evaluate the collector and clean it. If the cause of the breakdown lies in another situation, then it is not advisable for a non-specialist in working with such parts to disassemble it. It is better to buy a new electric motor.

Note! It is also not recommended to dismantle the engine impeller on your own, since when it is installed in its place, the balancing, which plays an important role, will be disrupted. Naturally, the electric motor will function, but not smoothly, which can lead to breakage of the bearings and noise when the stove is turned on.

Since the stove is in a disassembled state, it becomes possible to calmly view the other components of the cabin heater. So:

In order for more heat to come from the radiator, you need to dismantle it and wash it. It is fixed on the rear casing of the heater, which is removed by unscrewing the mounting screws. After this, the radiator can be easily removed and washed under the pressure of water flowing from a hose that is connected to the radiator inlet or outlet tube. The same pressure washes away dirt from the surfaces of the removed radiator.
To disassemble the air ducts and heater control mechanisms, you will need to remove the instrument panel on which the main air ducts are located.

Note! Usually the panel with the main air ducts is made as one piece, so it must be handled with the utmost care so that it does not have to be replaced later. After this, you need to remove the interior air ducts, which are secured with special screws, and the decorative lining of the floor tunnel. After this, you need to remove the interior air ducts, which are secured with special screws, and the decorative lining of the floor tunnel

After this, you need to remove the interior air ducts, which are secured with special screws, and the decorative lining of the floor tunnel.

Note! Under this trim there are air ducts for heating the feet, which are attached to the body with screws and latches.

The air distributor is removed from the dashboard by unscrewing the mounting screws and disconnecting the damper control rod.
Reassembly must be done in the reverse order of disassembly. If necessary, fix the damper seals with glue. You can also seal the attachment points of the hoses with the radiator with sealant.
When all the parts are assembled and installed in their places, the functioning of all components is checked and antifreeze or antifreeze is added. It all depends on personal preference.
At the final stage, they check the tightness of the attachment of the hoses to the radiator and the actual operation of the assembled stove.

For those who perceive information visually, it is recommended to watch a video with a detailed description of the actions and several photos that will help you do everything correctly.

Repair work can be carried out with your own hands, but subject to clear instructions. This will help you save a lot of money, because the price for services of this kind in car services is not cheap.

DIY resistor replacement

To replace the VAZ-2112 heater resistor with a new one, you will need to perform a number of simple steps:

Remove the “–” terminal from the battery to prevent a short circuit.
We dismantle the lining, the trim from the frame on the windshield and the upholstery for sound insulation.
The vacuum booster must also be dismantled, which will create difficulties when replacing a broken element.
There is a block with wires on the resistor that needs to be disconnected.
Now that access to the faulty element is provided, it is necessary to check its functionality. What if the problem of a non-working heater is not in this element, and we will replace the working resistor. To check, we will use an ohmmeter, which must be connected to the contacts one by one. If there is a deviation from the norm, you will need to change the resistor. Otherwise, you will need to look for the cause of the breakdown elsewhere.
We remove the old element and install a new one in its place.
The car is reassembled in the reverse order.

You already know where the heater resistor is located on the VAZ-2112 and how to replace it with a new one and can easily do this work yourself. And after these manipulations, your car’s heater will work like new. It will heat the interior at any speed and clearly respond to temperature control.

Ignition system

The second element of the car where you can find a resistor is the spark plugs. But not all candles are equipped with it.

It began to appear in the design of these elements not so long ago, and its task is to suppress radio interference.

POPULAR WITH READERS: Is it worth installing xenon lamps, the right approaches to choosing

By the way, there is now a lot of debate about whether it is needed in candles. After all, the resistor creates resistance, which ultimately affects the spark. But the stronger the latter, the better the combustible mixture ignites.

But in fact, the presence of a resistor has a slight effect on the quality of the spark, but only positively on the spark plug. A very strong spark charge leads to the destruction of the electrodes, and the resistance reduces the spark voltage.

But this is not its main purpose. A powerful spark discharge creates quite strong interference in the radio frequency range, which can affect the operation of a car audio system, mobile phone and any other equipment that is sensitive to this type of interference.

Interestingly, it is not necessary to install spark plugs equipped with resistors on the car.

The fact is that in many models a noise-reducing element is installed in the tips of high-voltage wires. Also, some types of wires themselves have quite good resistance, which is enough to suppress radio interference.

The resistor can also be installed in the distributor slider, and it is found there on many models. Its task is the same as that of a spark plug or tip.

It is important to understand that resistors cannot be used simultaneously in all of the listed ignition elements. When these elements are connected in series, all the resistance they create is summed up

When these elements are connected in series, all the resistance they create is summed up.

That is, if a resistor is installed in the distributor runner, tip, or spark plug, then they will create such a strong resistance that they will significantly weaken the spark charge, and it will no longer be able to properly ignite the mixture. And this will lead to interruptions in engine operation, loss of power, and increased fuel consumption.

Therefore, deciding whether to install spark plugs with a resistor on a car is necessary by carefully reading the technical documentation that comes with the car.

If the manufacturer indicates that the use of such candles is necessary, then it is better to use them.

DIY fuse replacement

One of the reasons why the heating system refuses to work is a burnt-out fuse for the VAZ-2112 stove, located behind the heater. The fuse that belongs to the heating system is marked F7. The current strength is at 30A. This part is also related to the operation of the cigarette lighter, optics washer, lighting system in the glove compartment and heating on the rear window. Thanks to such a system, you can easily determine that it is the fuse for the VAZ-21124 stove that needs to be replaced - not only the heater will refuse to work, but also all the elements that were listed above.

There is nothing difficult in replacing the VAZ-2112 heater fuse, you already know where it is located and what marking it has. We simply remove the burnt out part and install a new one in its place. But fuses don't just blow. This is caused by a short circuit in the car circuit. If it is not found and repaired, the fuse will blow again and require replacement. And this is much more difficult, because in some cases it is necessary to go through the entire circuit of the car in order to detect the short one.

Ignition system

The second element of the car where you can find a resistor is. But not all candles are equipped with it.

It began to appear in the design of these elements not so long ago, and its task is to suppress radio interference.

Interestingly, it is not necessary to install spark plugs equipped with resistors on the car.

The 1-2-3 speeds of the VAZ-2112 2004 heater do not work. As I understand it, you need to buy an additional heater resistor? Is it installed under the frill and screwed into the stove body?

If someone has already changed this additional resistor, tell me, is it possible, without buying it, to repair the old one, solder and replace the resistors? Does it have a thermal fuse and can it be replaced with a fuse? If so, what amperage fuse? Thanks in advance for your answers!

RDO 2108-8101081 is used on the oldest SAUO units, which have only 2 speeds. (0 A 1 2). RDO 2110-8118022-01 is installed on a modified heater until September 2003, the SAUO unit has 3 speeds (0 A 1 2 3). The most common malfunction in this resistance is that all stove speeds stop working, except maximum 3. The reason is that the thermal fuse is unsoldered (indicated by a red arrow), and is treated by soldering it in place. But if it is unsoldered later, you need to look in the direction of the motor, the motor takes a very large current (not lubricated, wear on the brush assembly, etc.). RDO 2123-2118022 has been installed on the latest heaters since September 2003, the SAUO unit has 4 speeds and does not have an auto mode (
0 1 2 3 4
).

Here I have a block like this, with stove speeds 0 1 2 3 4 I’ll try to repair the old one, there are only two resistors and a thermal fuse.

Added after 38 minutes 47 seconds:

Does anyone know what thermal fuse is needed to repair this additional resistor?

Because, if in the second picture the thermal fuse is soldered with low-melting solder (as far as I can see), then in the third picture it is simply replaced by a fusible temperature insert (a cylinder on two antennae) and it does not unsolder, but simply burns out.

When the VAZ 2109 stove does not heat well in the cabin, there can be a lot of reasons for this.

Recycling

In recirculation mode, the main air damper closes, after which the heater fan begins to draw air from the passenger compartment. This mode of operation allows you to block the access of unpleasant odors and polluted air from the street if, for example, you are driving a car along a dusty gravel road.

In winter, the recirculation mode allows you to warm up the car interior faster, since not frosty air, but warm interior air passes through the heater radiator. Accordingly, in summer, recirculation makes it easier for the air conditioner to cool down.

Types of recirculation drive:

Types of resistors, their features

Of the resistors described above that are used in the design of a car, two types can be noted - load, they are also constant and variable. In general, these are two main types that have fairly wide application in various fields.

Of course, there is a whole range of different resistors that differ in their design features. For example, thermistors, in which the resistance changes with temperature, or photoresistors, which change their parameters depending on the illumination. But we will not touch on them for now, but will consider only the two types indicated.

Power dissipation

In addition to resistance, the resistor has another important parameter - power dissipation.

Any resistor acts as a kind of limiter and, due to its resistance, conducts only a certain voltage and current through itself. At the same time, the excess that it did not miss does not accumulate in itself, but converts it into thermal energy and dissipates it.

Therefore, resistors are designated by power dissipation.

The discrepancy between this element and its dissipation power will lead to its overheating and destruction. Power dissipation is measured in Watts.

The power dissipation can be determined both by the voltage passing through it and by the current strength.

As for voltage, the formula for calculation looks like this:

P – power;
U – voltage in the circuit;
R is the resistance of the resistor.

To calculate the current strength, the formula looks like this:

P – power;
I is the current passing through the resistor;
R – resistance.

An important condition when choosing a resistor for this parameter is that its power dissipation should be twice as large as that obtained in the calculations.

For example, we have a current of 0.1 A and a resistor resistance of 100 Ohms.

Based on the formula, we obtain a dissipation power of 1 Watt (0.1 2 * 100 = 1), but for normal operation of the element we select a resistor with a dissipation power of 2 Watt.

Note that all manufactured resistors have a strictly defined power dissipation value, which makes their selection easier.

In addition, you can even visually determine what power dissipation the resistor has. Everything is simple here, the larger the element, the higher the value.

Here we looked at resistors - one of the most common elements in any electrical circuit of a car. After all, they allow you to control the basic parameters of electrical energy by influencing just one of its characteristics.

Finally, we note that during calculations it is necessary to monitor the dimension of the parameters. That is, use only amperes, volts and ohms, and if it is indicated that the current is 20 mA, then you should convert this value into amperes, obtaining a value of 0.02 A for calculations.

How to install a new stove

VAZ 2110 (10th family)

The standard ten stove is noticeably inferior to the new type stove: both in power and in ease of use. The process of installing a new stove is described in detail below. The result is more advanced heating in every sense.

New sample stove

It has a radiator n/o installed accordingly

Modernization of the cooling system “Kalinovsky style”!!

Maybe the rest of you should skip this point.

But since the steam outlet seems out of place for us now, we take it out and install this one instead

The one that was in the stove was replaced by agreement with the new one

Then we stomp to disassemble the car, remove the toad, wipers, Shumka, and we get this picture

Next we need to remove the left half of the stove (if you look at it from the face), here it awaits us

In the form of a bolt twisted from the interior, three more such ambushes await us when removing the right half of the stove, numbered 1, 2 and 3

For those who want to preserve the old stove in its entirety, there are two options, both hemorrhoids:

1. Remove the panel and then calmly unscrew these bolts from the interior.

2. Use a screwdriver to bend the mustache of the mortgages

Since I didn’t bother with the integrity of the stove, I just broke it off, and as a result we get this look

Next, we’ll halve the new heater to insert it, insert it and try it on, we see that it needs fastening to the body where there isn’t one, we mark the place where the fastener should be

We take a drill, drill, insert the embed, the fastening is ready

These holes shouldn't exist

Since I was not ready for this, I had to get out of it using improvised means:

From the body of an old stove

And glue it here

We find material to plug the other two holes, plug them (adhesive tape on top just in case)

We install the stove, look at the wiring connections

The wiring to the engine comes in one block

The old one sits on ground at one end, the other (+) goes through the block to the automatic control system, the output was bitten off from the engine of the old stove and the terminals were soldered to the new one (it’s better to buy the block in advance)

Extend the short wires to the resistance block that regulates the speed of the rotator

On the old stove the fuse module was three-pin, and on the new one it was 4-pin.

Accordingly, there are only three wires

It is necessary to throw another wire into the cabin to the SAUO, but for the system to work correctly, you need to move the white-red end to a free place, and put a new one in its place, this can be done either in the SAUO block, or in the stove block, I changed it near the stove there better access

To conduct a wire you need the wire itself and two mothers

Insert into the block

We stomp into the cabin, remove the self-propelled guns

We take out the 6-pin block from it

We insert our wire into the free socket

Insert the block into the automatic control system

Who has an old self-propelled gun system to fix the glitch with the damper, you need to swap the red and brown wires on the 13-terminal block, pins 2 and 8 (view from the face of the connector)

and there is no need to run a fourth wire.

Thanks for the information Kachan

We connect and secure the stove

We connect the terminal blocks to the damper

We fasten the stove near the right wing with pre-purchased fasteners

I didn’t have this, I made a homemade one from it. cap fasteners 8ki

We fasten in other places, on top is the one we made a little earlier

And two more fastening points at the bottom, on the studs with which the Shumka is attached

Let's go check the operation of the engine, check the dampers and make sure everything is working.

Next we connect the pipes, install the frill, Shumka, wipers and fill in antifreeze

As a result of the replacement, the following were damaged:

The old frill crumbled to dust when removed;
Shumka mounting stud — unscrewed together with the nut almost effortlessly (replaced with a self-tapping screw);
Well, the old stove itself - may it rest in peace!

It has become noticeably warmer in the cabin, all speeds of the turntable are working

Three main components of electric current

Electricity has become an integral part of our lives. It is used almost everywhere, including in vehicles.

This type of energy has three main components - voltage, current and resistance.

As for the last parameter, due to the possibility of creating additional resistance at any point in the electrical circuit, you can influence the first two parameters.

The main element for creating resistance is a resistor. This element is one of the most in demand, and not a single electrical circuit can do without it, and it will not be possible to replace it with anything else. And in any car there are plenty of electrical circuits.
