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 orange covering or labels. Do not probe, tamper with, cut, or modify high-voltage cables 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 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 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.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.
Danger
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. The use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed.
To check a fuse, look at the silver-coloured band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.
Fuses of the same amperage can be temporarily borrowed from another fuse location if a fuse goes out. Replace the fuse as soon as possible.
Underhood Compartment Fuse Block
To open the fuse block cover, press the clips at the side and back and pull the cover-up.
Caution
Spilling liquid on any electrical component of the vehicle may damage it. Always keep the covers on any electrical component.
A fuse puller is in the underhood compartment fuse block.
The vehicle may not be equipped with all of the fuses, relays, and features shown.

How to Replace the Fuse of the 2019 Chevrolet Bolt EV
To replace the fuse in a 2019 Chevrolet Bolt EV, follow these steps:
Materials:
- The new fuse of the correct amperage.
- Fuse puller or needle-nose pliers.
Instructions:
- Locate the Fuse Box: The fuse box in the Chevrolet Bolt EV is typically located in the engine compartment. Open the hood and look for a black plastic box with a removable lid.
- Identify the Correct Fuse: Use the fuse diagram provided inside of the fuse box cover to locate the specific fuse you need to replace. The diagram will indicate which fuse corresponds to the component or system that is malfunctioning.
- Turn Off the Vehicle: Before working on any electrical components, it’s essential to turn off the vehicle’s ignition and any related systems.
- Remove the Fuse: Using a fuse puller tool or a pair of needle-nose pliers, carefully grasp and pull out the fuse that needs to be replaced. Be gentle to avoid damaging the fuse or the fuse box.
- Inspect the Fuse: Check the fuse visually or using a multimeter to determine if it is blown. A blown fuse will have a broken filament or a discoloured appearance.
- Replace the Fuse: If the fuse is blown, replace it with a new fuse of the same amperage rating. It’s crucial to use the correct amp rating to avoid damaging the electrical system.
- Insert the New Fuse: Carefully insert the new fuse into the appropriate slot in the fuse box. Ensure it is seated securely.
- Close the Fuse Box: Once the new fuse is installed, close the fuse box cover securely.
- Test the Component: Turn the vehicle’s ignition back on and test the component or system associated with the fuse to ensure it is functioning correctly.
- Dispose of the Old Fuse: Safely dispose of the old fuse. If it is blown, it’s essential to replace it with a new fuse to maintain proper electrical function.
Tips:
- Always use a fuse with the correct amperage rating to prevent electrical issues or damage to the vehicle.
FAQs
Fuses protect electrical circuits by interrupting the flow of electricity when a circuit overload or short circuit occurs.
The fuse box in a 2019 Chevrolet Bolt EV is typically located in the passenger compartment or under the hood.
Look for a fuse with a broken filament or one that appears discoloured.
Typically, you’ll only need a pair of needle-nose pliers or a fuse puller.
No, it’s not recommended. Always replace fuses with the same rating to avoid damaging the electrical system.
Overloading a circuit, a short circuit, or a faulty component can cause a fuse to blow.
Make sure the car is turned off, and remove the key from the ignition. Also, wear gloves to protect against electrical shocks.
It’s best to use OEM (original equipment manufacturer) fuses to ensure compatibility and safety.
Regularly inspect fuses for signs of damage or wear, especially if you’re experiencing electrical issues.
If a particular electrical component stops working, such as the lights or radio, it could indicate a blown fuse.
No, replacing fuses is relatively straightforward and can be done with minimal tools and experience.
It’s not recommended, especially if the blown fuse affects critical systems like headlights or brake lights.
Exercise caution, as high-amperage fuses can carry significant electrical currents. Always use proper safety equipment.
No, fuses are designed to be a one-time use. Once they’ve blown, they need to be replaced.
