  Q: How to replace the right instrument panel fuse box on Chevrolet Suburban 1500?

  A:

  The first step to replace a right instrument panel electrical center or junction block involves removal of the right side end panel. Use a pull motion to detach the fuse block while pushing its tabs and remove it from the I/P to get to the retaining bolt. First use a screwdriver to disconnect the wire harness block from the fuse block. After that remove the I/P wiring harness block from the vehicle. You should mount the fuse block to the I/P wire harness block before securing it with the retaining bolt at 6 N.m (53 lbs in). After the open end of the fuse block enters the I/P successfully it can be put in place. Connect all wiring connectors to their designated spots on the fuse block and then replace the right side end panel.

  Q: How to replace the underhood fuse box on Chevrolet Suburban 1500?

  A:

  The replacement of the underhood Fuse Box demands starting with the removal of the negative Battery Cable then removing the left rear fender brace. You should start by removing the engine wiring harness junction block cover then disconnect the positive Battery Cable bolt attached to the junction block. You can reach the connectors by first detaching the chassis harness from the junction block before unsnapping the block from its bracket. The junction block can then move up to expose the connectors. The engine wiring harness junction block requires disconnection of seven connectors: the forward lamp harness (32 way) connector, the instrument panel harness (68 way) connector, the instrument panel harness (2 way) connector, the engine harness (68 way) connector, the engine harness (1 way) connector, the chassis harness (32 way) connector, and the chassis harness (2 way) connector. Detach then dismount the engine wiring harness junction block from its bracket. To install the engine wiring harness junction block begin by fitting it to the mounting bracket followed by installation of the chassis harness (32 way) connector and chassis harness (2 way) connector with an 6 n.m (53 lb in) torque. Following installation of the engine harness (68 way) connector comes the engine harness (1 way) connector which should be tightened to 6 n.m (53 lb in). The workshop should begin by securing the instrument panel harness (68 way) connector that requires 6 n.m (53 lb in) torque, then add the instrument panel harness (2 way) connector with the same level of torque. Next are forward lamp harness (32 way) connector installation with 6 n.m (53 lb in) torque. Secure the engine wiring harness junction block onto the bracket before attaching the chassis harness to the junction block with a torque of 6 n.m (53 lb in). The positive Battery Cable bolt requires installation onto the engine wiring harness junction block while tightening it to 9 n.m (80 lb in) torque before securing the engine harness junction block cover and left rear fender brace. Complete the procedure by connecting the negative Battery Cable and tightening its bolt to reach 17 n.m (13 lb ft).
