Most electrical circuits are protected by fuses.

Powerful consumers are connected via relays

All relays (except for the tailgate window defrost relay), power fuses and engine management system fuses are installed in the relay and fuse box located in the engine compartment on the left, behind the battery.

The rest of the fuses are located in the fuse mounting block installed in the passenger compartment at the left end of the instrument panel.

The switch for heating the back door glass is installed on the transverse beam under the instrument panel.

Fuse assignment (depending on equipment level): 1 - headlight washer pump relay; 2 - relay of the electric fan for forcing cold air; 3 - fog lamp relay; 4 - fuel injection blocking relay; 5 - fuel pump relay; 6 - high speed relay of the electric fan of the cooling system; 7 - relay low speed electric fan; 8 - air conditioning relay

In order to replace fuses or relays, you need to disconnect the negative terminal from the battery.

To access the fuses and relays in the engine compartment, press the three latches

Replacing fuses in Lada Largus

Remove the cover of the mounting block

Replacing fuses in Lada Largus

A faulty fuse is determined by a blown jumper visually or using a tester.

Replacing fuses in Lada Largus

You can use tweezers to remove fuses m, which is located on the cover of the cabin block (Fig. 3).

Replacing the fuses of the Lada Largus

A new fuse or relay should only be installed after the reason for its operation has been found.

We need to determine why the overload occurred in this circuit.

To access and replace the fuses in the passenger compartment, remove the fuse cover, which is located on the left side of the instrument panel.

On the inside of the cover of the mounting block there are spare fuses (rated for rated current 5, 10, 15 and 30 A), a tweezer-puller for removing the fuses from the block, and a diagram of the location of the fuses.
