In this article, you will find information about the fuses of the Chevrolet Express (models 2010, 2011, 2012, 2013, 2014, 2015, 2016, and 2017), 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 Express
The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you 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
Floor Console Fuse Block:
The floor console fuse block is located under the driver’s seat.
Engine Compartment Fuse Block:
The fuse block is in the engine compartment on the driver’s side of the vehicle.
