In this article, you will find information about the fuses of the Chevrolet Spark (M400) (models 2019, 2020, 2021, and 2022), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Chevy Spark
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. To check a fuse, look at the silver-colored 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.
Caution!
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire.
Location of Fuse Boxes
Instrument Panel Fuse Block:
The instrument panel fuse block is on the underside of the driver side instrument panel.
Engine Compartment Fuse Block:
The engine compartment fuse block is on the driver side of the vehicle, near the battery. To access the fuses, press the tab at the front of the cover, and lift the cover.
