• Q: How to replace the Fuse Box in the Body Wiring Harness Junction Block on 2005 GMC Savana 3500?

  A: One must begin Fuse Box replacement by disconnecting the negative Battery Cable followed by seat and cover removal. The initial step requires you to detach both the Fuse Box positive Battery Cable nut and cable from their block base position. Users with yf7 system must disconnect electrical connectors from the Fuse Box. The Fuse Box needs complete caged bolt loosening to release its block base holding tabs before it can be extracted from its base. Separate the Fuse Box base nuts (1, 3) along with disconnecting the wiring harness from the Fuse Box base until you can extract the Fuse Box base from under the floor. You must connect the wiring harness to the Fuse Box base before securing the Fuse Box base at floor studs while avoiding electrical connections (4, 5) from getting trapped under the Fuse Box base. Fasten the Fuse Box base nuts (1, 3) onto the floor studs while tightening them to 5 n.m (44 lb in). Install the Fuse Box onto the Fuse Box base while making sure the retaining tabs completely fit because you should then tighten all bolts to 5 n.m (44 lb in). If the vehicle has yf7 it requires electrical connector attachment before installing the positive Battery Cable to the Fuse Box while tightening the nut to 10 n.m (88 lb in). After installing the Fuse Box cover it is necessary to return the driver's seat properly while reconnecting the negative Battery Cable.
