Checking and Replacing Fuses in GMC Sierra

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. Circuit breakers protect the power windows and other power accessories. If the current load is too heavy, the circuit breaker opens and then closes after a cool down period, protecting the circuit until the problem is fixed or goes away.  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.

Caution!

  • Spilling liquid on any electrical components on the vehicle may damage it. Always keep the covers on any electrical component.
  • Do not add anything electrical to your vehicle unless you check with your dealer first.
  • Some add-on electrical equipment can keep other components from working as they should.
  • Add-on equipment can drain your vehicle’s battery, even if your vehicle is not operating.
  • Be sure you replace a bad fuse with a new one of the identical size and rating.
