Electrical System
High Voltage Devices and Wiring
Warning
Exposure to high voltage can cause shock, burns, and even death. The high-voltage components in the vehicle can only be serviced by technicians with special training.
High-voltage components are identified by labels. Do not remove, open, take apart, or modify these components. High voltage cable or wiring has an orange covering. Do not probe, tamper with, cut, or modify high voltage cable or wiring.
Electrical System Overload
The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems.
Fuses and circuit breakers protect the following in the vehicle:
- Headlamp Wiring
- Windshield Wiper Motor .
- Power Windows and Other Power Accessories
Replace a bad fuse with a new one of the identical size and rating. If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off.
Windshield Wipers
If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and the wiper control is turned off.
After the removal of the blockage, the wiper motor will restart when the
control is then moved to the desired operating position.
Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers.
If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.
Engine Compartment Fuse Block
The underhood fuse block is on the driver’s side of the engine compartment.
To open the fuse block cover, press the clips at the front and back an rotate the cover up to the side.
Caution
Spilling liquid on any electrical component of the vehicle may damage it. Always keep the covers on any electrical component.

- Check the fuse that blew. Usually, a broken or melted metal strip is found inside a blown fuse. When in doubt, check it against a fresh fuse.
- Place the New Fuse Here:
- Replace the blown fuse by inserting a fresh fuse with the same amperage into the same slot. Make sure it’s seated firmly.
- Check the Part:
- After turning on the car, check the part that is connected to the new fuse. For instance, make sure the headlights are working properly if you changed the fuse for them.
- Examine any problems
- If the replacement fuse blows either right away or very soon after, there might be an electrical issue. Seek expert help for a comprehensive examination.
- Secure the Fuse Box:
- Make sure the fuse box cover is securely fastened and closed after verifying that the replacement fuse is operating as intended.
Recall that using fuses with the appropriate amperage rating is crucial to avoiding electrical system damage.
