Power supply circuits of electrical equipment are protected by fuses
Powerful current consumers are connected via relays
Fuses and relays are installed in mounting blocks in the passenger compartment and in the engine compartment
Most of the fuses are installed in the passenger compartment relay and fuse mounting block, located on the left side of the instrument panel below under a plastic cover
In the same unit, an electronic body control unit is installed

To access the fuses and relays of the mounting block located in the engine compartment, press the latch at the back of the block (shown by the arrow) and remove the cover
Before you replace a blown fuse, you need to find out the cause of its blown and eliminate it
When troubleshooting, you need to look at the circuits that this fuse protects
Do not replace blown fuses with new ones designed for a different current strength, as well as homemade jumpers - this can lead to electrical appliances and even a fire
Remove the replaceable fuse with tweezers
This is what a blown fuse looks like (the jumper inside the holder, shown by the arrow, has blown and opened)
To replace the fuse, use a spare fuse of the same rating and color
If necessary, remove the relay or fuse by rocking it from side to side
Use special tweezers to replace fuses
