  Q: How to replace the left side instrument panel fuse box on Chevrolet Silverado 3500 Classic?

  A:

  The replacement of the left side instrument panel electrical center or junction block starts with removing the left end panel and knee bolster. All wiring connectors should be detached from the Fuse block followed by the removal of fuses and the turn signal relay from its back side. Using a screwdriver and a retaining bolt behind the Fuse block enables the removal of the block from its harness block position. Pressing on these retainers enables you to remove the Fuse block out of the vehicle. The installation of the Fuse block requires placing it onto the i/p assembly for proper insertion and attaching the wire harness block to its back. Secure the bolt with a torque of 6 n.m that equals 53 lb in. Follow the turn signal relay installation after you install the fuses based on the wiring diagram on the Fuse panel cover. The electrical connectors must be secured first while the knee bolster and left side end panel will be installed afterward.
