Most of the car's electrical circuits are protected by fuses installed in the mounting block
In the mounting blocks, relays of devices that consume high current are also installed.
The main mounting block is located in the instrument panel on the left side below and is closed with a cover, and the additional mounting block is installed in the engine compartment on its left mudguard.
Before you replace a blown fuse, find out the cause of the blown fuse and fix it.
When troubleshooting, it is recommended to look at the circuits that are protected by this fuse.
Replacing fuses and relays in the mounting block located in the passenger compartment
The location of the relays and fuses in the mounting block installed in the passenger compartment is shown in Figure 1, in Table. 1 and 2 show the purpose of relays and fuses.
Use special tweezers to replace the pin fuses.
Turn the fixing screw of the mounting block cover (Fig. 2)
Overcoming the resistance of the upper latches of the cover, remove the cover from the instrument panel (Fig. 3).
Use special fuse tweezers or manually remove the fuse from the connector (Fig. 4)
Install a fuse of the same rating as the removed one into the connector.
Remove the relay in the same way.
Install the relay of the same type as the removed one
Fuse body color and rating:
Current, A - Fuse body color
- 80 - Beige
- 40 - Orange
- 30 - Green
- 25 - Beige
- 20 - Yellow
- 15 - Blue
- 10 - Red
- 7,5 - Brown
- 5 - Orange
Fuse cases of different ratings are painted in different colors.
In addition, the fuse is marked with the numerical value of the current for which it is designed (nominal value).
Assignment of the relays located in the interior mounting block
Relay number - Name
- P1 - Relay for switching on the dipped headlights
- P2 - Relay for high beam headlights
- P3 - Wiper breaker relay
- Р4 - Relay-interrupter of direction indicators
- P5 - Rear window heating relay
- P6 - Fog lamp relay
- Р7 - Additional (unloading) relay
Before you replace a blown fuse, you need to find out the cause of its blown.
Remove the cause and then install a new fuse.
