2022 Chevrolet Silverado 1500 Fuse Box Diagram
Electrical System
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 wires that provide power to the devices in your vehicle.
- If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some features of the vehicle that is not needed to used and replace them as soon as possible.
- To check a fuse, look at the band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a fuse of the identical size and rating
Replacing a Blown Fuse
- Turn off the vehicle.
- Locate the fuse puller on the instrument panel end cap. See the Instrument Panel Fuse Block (Left) 0 370 or Instrument Panel Fuse Block (Right) 372.
- Use the fuse puller to remove the fuse from the top or side, as shown above.
- If the fuse must be replaced immediately, spare fuses are also provided on the instrument panel end cap or borrow a replacement fuse with the same amperage from the fuse block. Choose a vehicle feature that is not needed to safely operate the vehicle. Repeat Steps 2-3.
- Insert the replacement fuse into the empty slot of the blown fuse.
At the next opportunity, see your dealer to replace the blown fuse.
Headlamp Wiring
An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Has 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 will then restart. 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.
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.
Warning
Installation or use of fuses that do not meet GM’s original fuse specifications is dangerous. The fuses could fail, and result in a fire. You or others could be injured or killed, and the vehicle could be damaged.
- See Accessories and Modifications 0 338 and General Information 338.
- To check or replace a blown fuse, see Electrical System Overload 365.
Engine Compartment Fuse Block
- If the vehicle has a diesel engine, see the Duramax diesel supplement.
- The engine compartment fuse block is in the engine compartment, on the passenger side of the vehicle.
- Lift the cover to access the fuse block.
- Caution: Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
- A fuse puller is available in the left instrument panel end cap.
- The vehicle may not be equipped with all of the fuses, relays, and features shown.
