• Q: How to replace the instrument panel Fuse Box on 2007 Buick Terraza?

  A: The first task to perform junction block or instrument panel electrical center replacement is disconnecting the negative Battery Cable. Begin by removing the instrument panel right side endcap cover together with the i/p compartment. Prepare to replace the instrument panel accessory wiring junction block assembly by removing forward screws that connect it to the i/p carrier and then disassembling the bracket attachment nuts to the same carrier. The technician lowers the electrical center bracket of the i/p then guides the junction block into the stowage compartment space. You can pull the retaining tabs from the shroud/base to disconnect the electrical connector from the i/p wiring harness before moving the i/p accessory wiring junction block assembly away from the connector. The technicians must reinstall the connectors at their proper places into the base and shroud of the lower i/p accessory wiring junction block assembly. They need to verify that the main harness remains secure inside the lower shroud/base. Installation requires verification that every harness connector is firmly secured against its retention tab and alignment to i/p wiring harness junction block. First position the connector correctly against the base then carefully press the adapter to lock the outer retention tabs before performing the process for all connectors. Secure the i/p wiring harness junction block bracket onto its matching position at the i/p carrier bracket studs and use the supplied nuts to tighten them to 10 n.m (89 lb in). Fasten the 2 screws inside the i/p endcap while torquing them to 2 n.m (18 lb in), before adding the i/p compartment with the i/p right side end cap cover. After disconnecting the negative Battery Cable you must execute the power sliding door re-initialization process before reconnecting it.
