• Q: How to replace the underhood fuse box on 2007 GMC Sierra 1500 Classic?

  A: Starting the replacement of underhood electrical center or junction block involves disconnecting the negative Battery Cable while removing the left fender upper brace. Clear the tabs by lifting upwards the electrical center brace cover assembly and after removal of all fuses and relays proceed with the electrical center replacement. Perform these steps to rotate the electrical center on the studs located at while pushing on the tab and unfastening the bolt for all the connectors. Pushing the tabs lets you raise the electrical center beyond the housing as you disconnect all electrical connectors from the electrical center block. The replacement of the engine electrical center bracket requires bolt removal from four points to extract the assembly from the fender area. The front fender requires attachment of the engine electrical center bracket assembly followed by securing the 4 retaining bolts to 9 n.m (80 lb in). Insert the electrical center block stubs into their designated slots before securing them by the tabs and attach the wire connectors to the lower part of the electrical center block using bolts which need tightening to 9 n.m (80 lb in). The electrical center block should be placed into position until the tabs engage for lock. Install the lower part of the cover after which you must replace all fuses and relays with the cover removed according to the Fuse location information before installing the cover. Affix the fender upper brace to its position while torquing the 4 bolts to 25 n.m (18 lb ft). After reconnecting the negative cable begin the engine and check all system functionality.
