What front panel can be put instead of the standard one

The torpedo of the VAZ "five" today does not look very beautiful: angular shapes, minimal instrumentation, black and not very high-quality finishing material, which cracks and warps over time. For this reason, many owners seek to improve the interior and functionality of their car by installing a panel from other cars. On the VAZ 2105, with some modifications, you can introduce a torpedo from such cars:

• VAZ 2105–07;
• VAZ 2108–09;
• VAZ 2110;
• BMW 325;
• Ford Sierra;
• Opel Kadett E;
• Opel Vectra A

Installing a panel from a foreign car on a “classic” makes the interior of the car more representative

Before installing a particular front panel, you should evaluate whether it is suitable in size, what alterations are to be made and how to connect it.

Dashboard

The dashboard of the VAZ "five", as in any other car, is an integral part, since it contains devices for monitoring the technical condition of the car while driving. The tidy is installed on the left side of the torpedo opposite the steering wheel, which makes it easy to read information. The device is equipped with the following elements:

• 4 pointers;
• 6 indicator lights;
• 1 digital indicator (odometer).

Instrument panel VAZ 2105: 1 - outdoor lighting switch; 2 - indicator lamp for insufficient oil pressure in the engine lubrication system; 3 - liquid temperature gauge in the engine cooling system; 4 - battery charge indicator lamp; 5 - block of control lamps; 6 - speedometer ; 7 - summing distance meter; 8 - rear window heating switch; 9 - plugs for instrument panel mounting screws; 10 - three-position heater fan switch; 11 - control lamp for switching on the high beam; 12 - control lamp for turning on direction indicators; 13 - control lamp turn on side lights; 14 - voltmeter; 15 - instrument cluster; 16 - fuel gauge; 17 - fuel reserve warning lamp; 18 - rear fog lights switch

The following devices are used in the instrument panel:

• speedometer;
• block of signal lamps;
• car mileage counter;
• voltmeter;
• coolant temperature sensor;
• fuel level sensor in the tank.

What dashboard can be installed

The dashboard of the "five" can be improved in several ways:

• perform tuning using new lighting elements, scales and instrument arrows;
• implement a combination of devices from another machine;
• make tidy yourself by setting the necessary pointers.

It is possible to modify the shield by replacement, but only with careful selection and fitting of the device for a standard torpedo, as well as after preliminary study of the connection diagram.

From another VAZ model

Some owners install a panel from Kalina on the fifth Zhiguli model. The product looks modern, and the information from the devices is read much better. The essence of the refinement comes down to installing a new shield in a standard case, for which it needs to be filed, trimmed, and assembled with a new mechanism. After completing the mechanical work, it is necessary to dock the new dashboard with wiring, checking the performance of all pointers and indicators.

On the VAZ 2105, you can install a combination of instruments from Kalina

From "Gazelle"

If you like the instrument cluster from the Gazelle, then you can also install it. At the same time, you need to understand that you will have to redo the wiring by making adapters due to the mismatch of the connectors, and then install the product in a standard case with the accompanying adjustment and refinement steps.

To introduce a combination of devices from the Gazelle, you need to redo the wiring, connectors, fit the shield to the standard case

From a foreign car

Many owners of the classic "Lada" in the process of tuning their car install a dashboard from foreign cars. Basically, products from cars manufactured in the late 1980s - early 1990s are suitable for these purposes. One of these is the BMW E30, Audi 80.

On the VAZ 2105, you need to select a dashboard that fits in size and does not require cardinal alterations in the wiring

Malfunctions of the dashboard VAZ 2105

In equipping the dashboard of the car in question, a minimal set of indicators is used, but they can also work intermittently at times. Therefore, you need to be aware of possible malfunctions and be able to eliminate them, especially since this does not require special tools.

Diagnostics and replacement of individual devices

Since each of the indicators in the dashboard displays the state of a particular vehicle system, the occurrence of problems causes inconvenience during operation. Therefore, it is desirable to eliminate any malfunctions as soon as possible.

Fuel gauge

The "five" uses a fuel sensor BM-150, located in the fuel tank. Structurally, the device consists of a variable resistor, the resistance of which varies from a moving lever with a float. Also on the lever is a contact that turns on the lamp on the tidy, signaling a small amount of fuel in the tank (4–6,5 liters). The instrument panel has an arrow pointer that displays the level of gasoline.

The arrow indicator installed on the instrument panel shows the level of fuel in the tank

If there is a suspicion that the fuel sensor is not working correctly (constantly full or empty tank), then you need to check its resistance:

• with an empty tank, the resistance should be in the range of 315–345 ohms;
• when half filled - 108-128 ohms;
• at full - 7 ohms.

If the sensor needs to be replaced, it is enough to remove the wires, unscrew the fasteners and remove it from the gas tank. There are practically no problems with the arrow pointer.

To remove the fuel level sensor, you must remove the pipe, wires and unscrew the mount

Voltmeter

The voltmeter provides voltage control at the battery terminals when the engine is not running, and during its operation it shows the voltage that the generator produces. When the arrow is in the green zone, this means that the voltage of the on-board network is normal. When the pointer moves into the red zone, this indicates a weak alternator belt tension or a malfunction. The white area of ​​the indicator indicates an unsteady charge-discharge mode. The occurrence of problems with the readings of the voltmeter, as a rule, is caused by a break in the wiring. Therefore, you need to check the power supply circuit to the device with a multimeter.

Voltmeter shows voltage at battery terminals

temperature gauge

VAZ 2105 is equipped with a TM-106 temperature sensor, which is wrapped in the cylinder head on the left side. The sensor consists of a resistor whose resistance changes depending on the temperature of the antifreeze. Readings are displayed by a temperature gauge on the dashboard.

Engine coolant sensor installed in the cylinder head

If the device does not work or there are suspicions about the correctness of the readings, you need to diagnose the sensor. To do this, turn on the ignition, pull the conductor from the sensor and close it to ground. If the arrow deviates to the right, the checked element is considered non-working. If there are no deviations of the pointer, then a break has occurred in the wiring, which will require a dial-up with a multimeter. In case of problems with the sensor, we replace it as follows:

1. Remove the negative terminal from the battery.
2. Drain the coolant from the engine.
3. We tighten the rubber cap from the sensor and disconnect the wire.
   

   Only one terminal is connected to the sensor, remove it
4. We unscrew the sensor with a deep head and an extension cord and install a serviceable one in its place.
   

   We unscrew the coolant sensor with a deep head

Temperature, °C	Voltage supplied to the sensor, V	Sensor Resistance, Ohm
30	8	1350 – 1880 Feet
50	7,6	585 – 820 Feet
70	6,85	280 – 390 Feet
90	5,8	155 – 196 Feet
110	4,7	87 – 109 Feet

Oil gauge

Pressure control in the lubrication system of the Zhiguli fifth model is carried out by means of a sensor on the engine block, as well as a light bulb in the tidy. The indicator lamp lights up when the ignition is turned on and goes out a couple of seconds after starting the power unit. If the lamp indicates insufficient oil pressure in the system while the engine is running, you first need to check the oil level with a dipstick and only then proceed with troubleshooting. The absence of a glow of the lamp may indicate its burnout. If the oil level is normal, the lamp is working, but at the same time it glows all the time, you need to replace the sensor.

If the oil pressure in the system is low, the light will come on.

This will require a 21 ratchet socket and a new part. Replacement consists of the following step-by-step actions:

1. Remove the rubber boot and terminal from the sensor.
   

   To dismantle the oil sensor, remove the cover and wire from it.
2. We unscrew the element with a head or a key.
   

   Unscrew the sensor with a key or head
3. Install the new sensor in reverse order.

Speedometer

Using the speedometer, the driver can control the speed and distance traveled (tachometer). The main malfunctions that occur with the speedometer are due to cable malfunctions, through which rotation is transmitted to the device from the gearbox. The flexible shaft frays over time or its tips wear out. As a result, speed readings are missing or inaccurate.

The speedometer displays the speed at which the vehicle is moving.

To replace the cable, you need to prepare the following tools:

• flat screwdriver;
• passages;
• spanners;
• wire or cord up to 2 meters long;
• new drive cable.

To replace, you need to do the following:

1. We de-energize the onboard network.
2. We remove the instrument cluster.
3. Using pliers, unscrew the fastening of the cable to the speedometer.
   

   The speedometer cable is attached to the device with a nut.
4. We tie the wire to the cable nut.
   

   We tie a piece of wire to the eye of the speedometer cable
5. Having lowered under the car, we unscrew the nut securing the cable to the drive, after which we pull the part towards ourselves.
   

   From below the cable is fixed to the speedometer drive
6. We tie the wire to a new cable and pull it into the salon.
7. We untie the wire and collect everything in its place.

Before installing a new flexible shaft, it is recommended to disassemble and lubricate it, for example, with Litol.

Before installing the speedometer cable, it is recommended to lubricate

Switches

Switches located on the tidy sometimes fail. This manifests itself in the form of a lack of fixation, jamming in one of the positions, or poor contact of the internal mechanism. In this case, the part must only be replaced. Due to the low cost of the switches (50–100 rubles), their repair is impractical. To replace a failed switch, follow these steps:

1. Disconnect the wire from the battery negative.
2. Pull the key out of its seat.
3. We disconnect the wires.
   

   Remove the wires from the switch one by one.
4. Installing a new part.

Cigarette lighter

If earlier the cigarette lighter was used for its intended purpose, today it is possible to connect various modern devices through it (chargers, a compressor for pumping wheels, a vacuum cleaner, etc.). Sometimes it happens that the cigarette lighter stops working.

Through the cigarette lighter, you can connect the charger to the phone, laptop, as well as a compressor for inflating wheels

The main causes of malfunctions are:

• burnt out spiral;
• poor contact;
• blown fuse (F6 10 A);
• wiring problems.

With a burnt contact in the socket, you can try to clean it or simply replace the assembly part. To do this, do the following:

1. We dismantle the instrument.
2. We remove the wires that supply voltage to the cigarette lighter.
3. Unscrew the nut and remove the device.
