Where is the fuse located

Manufacturers of VAZ-2114 did not install acoustic systems on their cars. Because of this, vehicle buyers were forced to independently search for suitable radios and install them with their own hands.

Electricity is supplied to the installed device through the cigarette lighter (an element with a high energy consumption). To avoid short circuits and surges in the circuit, it is necessary to install additional protection that is responsible for the radio and turns it off in the event of an unforeseen situation.

This fuse is located in the wiring box, which is located in a special block under the hood of the car. To access it, you need to remove the cover and find the desired part among many others. On most VAZ models it is located third from the bottom (in the left row) and is marked F7.

For the VAZ-2114, it is allowed to use a part designed for a current of 20 or 30 A. Such fuses can provide effective protection not only for the speaker system and cigarette lighter, but also for any other elements.

Mounting block Samar

What are the differences between the mounting blocks installed on the Lada Samara? BRIEFLY: There are 3 types of blocks: 1 - the first rear window washer relay (the block has 11 relays). 2 - first headlight wiper relay (the block has 9 relays). 3 - first fan relay (the block has 9 relays). Such a block can be installed instead of the second one, then we place a jumper on relay 1 (pins 30 and 87). And everything will work, except for the rear fogs, they will either work normally, or they can be turned on at any time.

DETAILS: First view - Blocks with 11 relays

There are 2 types of them: Old style

The very first

And new

Analogue to the first

They are almost no different, the new model simply has a different arrangement of relays and fuses and the fuses themselves are “knife” ones, which hold well. They have 11 relays and 16 fuses. The Ш11 connector is located on the side and the contacts face the interior. Both have a rare transparent cover))) The new model unit has one board, making it easier to repair and solder.

Characteristics: Dimensions:

there are three fuses for the dimensions (7, 9 and 10), and they are powered by Ш4/4, Ш4/13 and Ш3/13 through a button and a turn switch, and this is done for the “parking light” function: by pulling out the key you can turn on the turn switch left or right dimensions, while the license plate and instrument lights did not turn on. And the button turned on all the dimensions and lighting. After 1988, this function was removed, and all three contacts were connected by one wire, which was connected directly to the size button.

Fan:

when mass was supplied from the sensor (or from the injection system controller) to Sh6/9, relay K9 was turned on (if the ignition is on) and the plus was supplied to Sh5/5 to the fan.

Note:

The fan relay winding is connected to fuse 4, to which the heater fan and window washers are connected. If it burns out, the engine cooling fan will not turn on.

Headlight cleaners:

when the light was turned on, a plus appeared on Ш3/8, then to fuse 3, from it to the headlight wiper relay K6. If you turn on the windshield washer, the relay turns on, and if the headlights are on, then a plus is supplied to the motors at Ш7/3.

If a headlight wiper button was installed, then instead of a relay, a jumper was placed on contacts 30 and 87 (power went to the relay in the engine compartment), and it was turned on by a button through contacts Ш6/7 and Ш4/15.

Charge genes:

this blocks may differ. On the old-style block, power was supplied to the gene excitation winding (Ш7/9) through a charge lamp from Ш4/18 and 100 Ohm 2 W resistors from the ignition. There may be no resistors on the new block, which means the generator will not be excited at idle, and it may be that Sh7/9 was connected only to Sh7/4 which was not connected anywhere (apparently something in the wiring was changed, but we didn’t know anything about it we know). This means that if such a moment arises, you need to connect the gene to the tidy and install resistors...

Rear window washer:

The K1 rear window washer delay switch turned on, so that we seemed to push the lever away from us all the way for a fraction of a second, and the water still flowed for about five seconds. So that we don't get distracted from the road while washing the rear window)))

Rear fogs

From the size button, the green wire went to the fuse (it dangled next to the button, power appeared if you turned on the low or high beam headlights), from it to the button, from the button to Ш2/10 and to the rear lights.

Sh3/21 was connected to Sh11/17, I don’t know why. And I don’t know what Sh10 is for either. Well, there are some anomalies where there is a hole for the K4 lamp serviceability relay, but there are no contacts, that is, jumpers are not needed, everything in the block is already connected directly. Relay:

K1 - Rear window washer time relay K2 - Turn signal and hazard warning relay K3 - Windshield wiper relay K4 - Relay for monitoring the health of lamps (or a jumper, or nothing) K5 - Relay for turning on the high beam headlights K6 - Relay for turning on the headlight wipers K7 - Relay power windows power supply K8 — Relay for turning on the sound signal K9 — Relay for turning on the electric motor of the engine cooling system fan K10 — Relay for turning on the heated rear window K11 — Relay for turning on the low beam headlights Fuses:

The second type is blocks with 9 relays

The most popular one, which came with a europanel

And so

They differ from each other only in the location of the relays and fuses. They differ from blocks with 11 relays in the connection of some circuits, the number of relays (9 pieces, there is no delay relay for the rear window washer and there is either a headlight wiper relay or a fan), the number of fuses for the dimensions and the fuses themselves are marked differently. Connector Ш11 is located at the top. The block, which in the top photo consists of one board, is easier to repair.

Blocks with 9 relays (both the first in the photo and the second in the photo) come in 2 types:

The first type of blocks with 9 relays: K1 - headlight wiper relay

They have:
Fan:
on Sh5/5 plus it is supplied directly, and the fan was turned on by connecting it to ground with a sensor or a switch controlled by the brains of the injector. The sensor is designed for higher current. Therefore, sometimes a situation arises when, after replacing the unit, the fan does not turn off. In this case, you can embed a relay (30 and 87 into the break in any wire to the fan, 86 to the ignition positive, 85 to the sensor or injector brains).

By the way, if the injector removes the terminal from the temperature sensor (which has 2 wires), the controller will enter emergency mode and turn on the electric fan. Dimensions:

Due to the removal of the parking light, we decided to install 2 fuses (F10 and F11), and hang the dimensions and lights on them, and they were powered only from Ш4/4, which went to the button. This means there will be no parking light.

” />

The released fuse was thrown onto the window regulators (which is F6 on these blocks); on a block with 11 relays they were powered by the fuse for the interior lighting and brake lights. Headlight cleaners:

they were also powered, but the relay was turned on by applying a plus (from the button) to Ш2/16.
Charge genes:
Ш7/9 (per gene) and Ш4/18 (tidy) are always connected together.
But there are options where there are resistors (a white circle is drawn on the mounting block), this is if there is no Europanel. The remaining blocks are only for the Europanel, where the resistors are located in the tidy. Rear window washer:
connected directly without a relay, that is, as long as we hold the lever, water flows.

Rear fogs

There are 2 options for wiring the instrument panel: — Button with fixation: when the headlights were turned on, power went to Ш3/8 to fuse 1. From it to the headlight wiper relay and through Ш3/21 to the button. From the button on Ш2/10 to the lights. — Button without fixation: there is a relay for the rear fog lights, powered by a dangling fuse next to it (a constant plus). The “permitting” wires from the sidebar button and front fog lights go to it. The relay is controlled by the minus supply from the button, it supplies power to Sh2/10 to the rear fogs.

On cars with E-Gas (since 2011), on Ш3/21 there is constant power supply for the electrical package unit. It controls the door locks and rear fog lights. This option uses a non-latching button.

The second type of blocks with 9 relays: K1 - fan relay:

for the electronic gas pedal
Headlight cleaners:
their relay replaced the fan relay, so Ш2/16 (plus from the button) went directly to Ш7/3 to the switch under the hood, which turns on the motors.
And on Sh3/21 a constant plus was supplied to the immobilizer (more precisely, the electrical package unit, there is also the rear fog light relay) and the central locking. Fan:
freed contact Ш3/8 (there was a plus from the light) and Ш3/13 (there was a plus from the dimensions on the high and low torpedoes) feed the winding, these contacts go to the injector wiring, and with them it turned on the K1 switch, while on Ш5/ 5 was supplied plus to the fan.

Therefore, sometimes a situation arises when the fan runs on light and dimensions, and sometimes it doesn’t work at all. You need to reconnect, or put a jumper and remove the relay. The rest is the same as the sixty. Well, when AvtoVAZ realized that for several decades people have been mistakenly engaging reverse gear instead of first (because they are nearby), Sh6/1 began to be used, it was connected to the reverse light switch, and on Sh2/9 (on the seventeenth it was connected to Ш11/19) a plus appeared so that the immobilizer-unit of the electrical package would beep when reverse gear is engaged. This is mainly for cars with an electronic gas pedal. Relay:

K1 - Relay for turning on the headlight cleaners OR K1 - Relay for turning on the engine fan (E-Gas) K2 - Relay-breaker for direction indicators and hazard lights K3 - Relay for the windshield wiper K4 - Relay for monitoring the health of brake light lamps and side lights Or jumpers if missing relay K5 - Relay for turning on electric windows K6 - Relay for turning on the sound signal K7 - Relay for turning on the heated rear window K8 - Relay for turning on the high beam headlights K9 - Relay for turning on the low beam headlights

TOTAL:

There are 3 types of blocks: 1 - the first rear window washer relay (the block has 11 relays). 2 - first headlight wiper relay (the block has 9 relays). 3 - first fan relay (the block has 9 relays). Such a block can be installed instead of the second one, then we place a jumper on relay 1 (pins 30 and 87). And everything will work, except for the rear fogs, they will either work normally, or they can be turned on at any time.

Service

. Sometimes the terminals can become loose, for example at the turn signal relay, and it starts to ring. Therefore, we try not to touch the relays and fuses again. The blocks are located in an air supply box, where it is constantly damp. Contacts under voltage especially oxidize and even crumble, especially at plug 11. Therefore, firstly, we clean the drain holes from leaves, seeds, insects, etc., clean out dirt or even remove the drain rubber bands (especially the small one next to the block). Secondly, we coat the plastic with sealant, which prevents water from flowing onto the block when it rains; the water should go to the sides. And thirdly, disconnect plug 11, smear lithol there and put it in place. If the cover is torn, we replace the harness as a whole or just the cover (here you will have to pull out the terminals). And let's see if it's well wrapped with electrical tape. You can also cover the block with a cut out anti-freeze bottle or something else. It is advisable to disassemble the new unit and coat the board with varnish (you can use a spray can for painting work) or Movil (it does not conduct current). If during replacement we tore off the studs but pieces remained sticking out, you can buy these fasteners on the construction market

I don’t know why, probably to attach something. They fit perfectly. You can put washers and screw them onto the remaining studs. But they rust instantly, right on the same day they will be covered with rust, with a layer of about two centimeters, so before installation we smear them with oil or Movil

Photos from the salon

Well, we've sorted it out a little bit.

How to remove the mounting block VAZ 2114

To begin with, there was a malfunction: the washer and wipers did not work, the stove failed. Tired of hitting the fuse block. They let me leave work early, so I decided to get down to business. It’s warm outside, there’s water everywhere, but the washer doesn’t work...
