2005 Buick Rainier Parts Questions & Experts Answers

• Q: How to replace the underhood fuse box on 2005 Buick Rainier?

  A: The replacement of the underhood electrical center or junction block starts with disconnecting the negative Battery Cable. Begin by pressing tabs on the junction block cover to expose inward and gently lifting it off the cover. To take out the fuse relay center cover you must lift upward to free its retaining tabs. Mark down the harness end bolt locations prior to its removal from the fuse relay center. Remove all bolts securing the fuse relay center until you can take the fuse relay center out from the junction block bracket. The bottom of the fuse relay center can be accessed by detaching the wiring harness ends using downward pulling force. Once the wiring ends are detached install screws holding the junction block bracket to retrieve the bracket from the vehicle. Install the junction block bracket first before tightening its bolts to 6 n.m (53 lb in). Secure the fuse relay center to the harnesses by installing bolts which should be tightened to 6 n.m (53 lb in). Fasten the harness end bolts before putting the fuse relay center cover into position over its bolts and pressing downward to snap the tabs together. Last but not least install the junction block cover while pressing down the tabs to engage them.
