    Q:
    How to replace the RH end panel and the Fuse Box on Chevrolet Avalanche 1500? Posted by Customer
    A:
    The first task to change the right side end panel and fuse block requires removing the right side end panel. The tabs need to be pushed for detaching the fuse block before you gently pull it from the instrument panel to reveal the retaining bolt. A screwdriver will help you detach the wire harness block from the fuse block for removing the I/P wiring harness block from the car. Join the fuse block to the I/P wire harness block by inserting the retaining bolt and tighten it to 6 N.m (53 lb in). The installation process includes fitting the fuse block into the I/P until it clicks while performing wiring connector attachment to the fuse block then reattaching the right side end panel.
