The fuse box is an element of the vehicle's electrical system and serves to conveniently locate electrical fuses and relays in one place.
On different car models, the number and location of the blocks differs, but in most cases, there are two of them, and they are located, one under the hood, the other inside the passenger compartment under the panel.
The interior fuse box controls the interior's electrical systems, such as the heater, air conditioning, radio, and interior lighting.
The fuses of the second block, located in the engine compartment of the car, control the electrical elements of the engine or other electromechanical parts of the car, such as the ignition systems, starter, pumps and cooling system.
Reasons why the fuse block may fail:
- Electrical circuit overload or short circuit.
- Oxidation or corrosion of block contacts.
- Mechanical damage.
- Ingress of moisture or other contaminants.
- Natural wear and tear.
If you do not have the appropriate experience and tools, then it is better to entrust the replacement of the fuse box in the car to the professionals of a car repair shop.
Stages of replacing the fuse box in a car service:
- First, the problem is diagnosed.
- Before starting work, you must disconnect the battery to avoid short circuits.
- Depending on the car model, the protective elements of the unit are dismantled.
- Disconnecting and dismantling the old unit.
- Connection and installation of a new unit.
- Carrying out diagnostics of the entire electrical system of the car.
- Installations of protective elements.
When operating a car, regularly carry out preventive maintenance work on the fuse box; we recommend checking its condition, cleaning it from dirt, replacing damaged fuses, and although repair work on servicing the unit can be done independently, it is better to entrust repair or replacement of the fuse box to car service specialists.
