How to replace the left instrument panel fuse box on GMC Sierra 1500?

The replacement process of the left instrument panel electrical center or junction block begins by removing both the left side end panel and knee bolster. Remove and disconnect all wiring connectors from the Fuse block and all fuses should be taken out. Removing the turn signal relay first from the back of the Fuse block is necessary before removing the bolt behind the Fuse block. Inserting a screwdriver between the Fuse block and wire harness block allows removal of the Fuse block from the vehicle by applying pressure to its retainers. Insert the Fuse block onto the i/p assembly until it clicks before attaching the wire harness block to the Fuse block backend. Fasten the bolt by torquing it to 6 n.m (53 lb in). Apply the wiring diagram from the Fuse panel cover to reinstall fuses as part of installing the turn signal relay. First reconnect all electrical connectors then replace the knee bolster before putting in the left side end panel.
