GM 84446208 Block Assembly, Rear Body Fuse

Removal steps 1. Park on level ground, set the parking brake, remove the key, and put on safety glasses and gloves. 2. Open the access area (engine compartment or passenger footwell) and remove any trim or covers that block access to the fuse box; designs vary so proceed according to the vehicle's access. 3. Disconnect the negative battery cable first and move it aside so it cannot contact the terminal; if the vehicle has a secondary battery or additional power source, isolate those as well. 4. Remove the fuse box cover and document the fuse/relay layout with photos or labels for reassembly. 5. Label or mark each wiring connector and take photos so you can restore original routing and connections. 6. Release and disconnect all wiring harness connectors and grounding straps from the fuse box, using the connector release tabs and a small pry tool if needed. 7. Remove the fasteners or clips that secure the fuse box to its mounting bracket or support (fastener type and count vary by design). 8. Carefully lift the fuse box assembly free, supporting wiring to avoid pulling or bending terminals. 9. Inspect the harness ends, terminals, and mounting surfaces for corrosion or damage and clean or repair as required. 10. Store the removed unit and small hardware in a labeled container to keep parts organized. Installation steps 1. Verify the replacement fuse box matches the original in connector arrangement and fuse/relay positions before beginning. 2. Position the fuse box onto its mounting bracket and align it without forcing wiring; confirm harness routing matches your photos or labels. 3. Reinstall mounting fasteners and secure the fuse box so it seats properly; tighten hardware snugly but do not use specified torque here. 4. Reconnect all wiring harness connectors and ground straps, ensuring each connector fully seats and any locking tabs engage. 5. Reinstall relays and fuses into their original locations using your reference photos; replace any fuses that appear damaged and always use correct amperage ratings. 6. Refit the fuse box cover and any trim pieces that were removed for access. 7. Reconnect the negative battery cable (and any secondary battery connections) and ensure terminal clamps are secure. 8. Turn the ignition to accessory and verify operation of a few electrical circuits (lighting, horn, power accessories) and confirm no new warning lights are present. 9. Scan for diagnostic trouble codes and clear or record them as needed, then perform a brief functional test or short road test to confirm reliability. 10. Perform a final visual check for secure mounting, proper wire routing, and absence of loose tools or debris. Repair tip: Keep photos and labeled tape for each connector - that saves time and prevents miswiring; use dielectric grease on corroded terminals after cleaning.
