The 99 Chevrolet Silverado Fuse block access door is on the driver’s side edge of the instrument panel. Pull off the cover to access the fuse block. You can remove fuses with a fuse extractor. The fuse extractor is mounted to the fuse block access door. To remove fuses if you don’t have a fuse extractor, hold the end of the fuse between your thumb and index finger and pull straight out. You may have spare fuses located behind the fuse block access door. These can be used to replace a bad fuse. However, make sure it is of the correct amperage.
