• Q: How to replace the underhood fuse box on 2000 Buick LeSabre?

  A: The replacement process for the underhood Fuse Box begins by removing the negative Battery Cable followed by taking off the underhood electrical center cover. The positive Battery Cable nut needs disconnecting from the underhood electrical center and the wiring harness clip needs detaching from the accumulator cover before moving the cables safely out of reach. Disconnect the evaporator hose from the accumulator cover followed by removing the accumulator cover and its container from the housing. Begin the repair by unplugging the four cam lock connectors after loosening three screws that secure the underhood electrical center connectors. Then remove the assembly from its base position. The process starts with disconnecting the engine harness connector before you remove the underhood electrical center which requires you to unscrew and untighten base nut and bolt and finish by discarding the base assembly. To mount the underhood electrical center base into the vehicle, install it and secure it using the provided nut and bolt while tightening both pieces to 9 n.m (80 lb in). Connect the engine harness connector to the underhood electrical center and use the center connectors to fasten them by tightening all three retaining bolts to 6.6 n.m (58 lb in). After inserting the underhood electrical center into the four retaining locks install the accumulator and cover before securing the wiring harness into the clip on the accumulator cover which should position cables onto the stud. Install the positive Battery Cable nut at the underhood electrical center and torque it to 15 n.m (11 lb ft). After that, position the cover onto the underhood electrical center and connect the evaporator hose to the accumulator cover and secure the negative Battery Cable.
