Warning! Before replacing a fuse, it is necessary to determine and eliminate the cause of its blown. In order to avoid failure of electrical equipment, fuses with an increased rating or home-made fuses should not be installed.
1. We prepare the car for work and disconnect the wire terminal from the negative terminal of the battery (see "Preparing the car for maintenance and repair").
2. Opening the hood, press the two latches and open the cover of the mounting block.
3. By the serial number on the body of the mounting block, we find the fuse of the faulty circuit.
4. The fuse and relay mounting block contains tweezers for removing fuses from their sockets. We squeeze the fuse case with tweezers and remove the fuse from the block.
A bad fuse can be identified by a blown filament.
Recommendation: Sometimes the thread of the fuse remains intact, while its connection inside the fuse is broken. It is impossible to visually determine such a malfunction. In this case, you can evaluate the condition of the fuse using an ohmmeter.
5. Install a new fuse of the appropriate rating.
6. If it is necessary to replace the relay, remove it from the block.
Tip: You can make sure that the relay is malfunctioning if you install another, known to be good relay in its place (relay for headlights, heated rear window or power windows).
8. Install a new relay of the same type. At the same time, we combine its conclusions with the grooves of the mounting block and sink them all the way.
9. Close the cover of the mounting block and connect the battery.
