• Q: How to replace the rear Fuse Box on 2005 Buick LeSabre?

  A: The first step to replace the rear junction block requires removal of the rear seat cushion together with Battery Cable disconnection. Begin by removing the rear fuse block cover only when the ignition key rests in off or lock along with all electrical power turned off for safety reasons. Detach both the positive Battery Cable nut and cable from the rear electrical center by releasing the four retaining clips to allow raising the center and flipping it over. Disconnect all components attached to the fuse block after separating its three fastening connectors. Installation requires you to attach all connectors back to the rear fuse block before starting the fasteners by hand to reach a torque of 7 n.m (62 lb in). Replace the rear electrical center into the base assembly where all clips should properly lock in. After that reinstall the positive Battery Cable along with its nut before tightening the nut to 15 n.m (11 lb ft). The process ends with reattaching the rear seat cushion while reconnecting the negative Battery Cable.
