Problems with the fuse box
Corrosion or damage to the contacts in the fuse box can lead to interruptions in the operation of lighting, fans and other systems.
Oxidation of connectors
Due to exposure to moisture, contacts in connectors, especially in the engine compartment and trunk, can oxidize, which causes interruptions in the operation of headlights, alarms or electric pump.
Weak generator
Over time, the generator can lose efficiency, which manifests itself in the form of a discharged battery, dim headlights and unstable operation of electronics.
Malfunctions of the central lock and window lifters
Failure of motors or control buttons can be caused by wear or damage to the wiring.
Problems with the wiring of the rear lights
A common problem is chafing or damage to the wires due to vibrations or improper installation.
Error in the crankshaft position sensor
A malfunction in the wiring or connectors of the sensor can cause problems with starting the engine.
To prevent such malfunctions, it is recommended to regularly check the condition of the wiring, connectors and fuses, and protect electrical components from moisture and dirt.
