Mercedes Sprinter T1N Primary Fuse Box Assembly – OEM Replacement | #9015400150 (2002–2006)

DESCRIPTION:

The fuse box is the electrical backbone of your T1N Sprinter — and when it starts to fail, the symptoms can be maddening to diagnose. Intermittent electrical faults, randomly blown fuses, non-functional systems, and poor relay contact are all classic signs of a fuse box that has corroded, cracked, or degraded from age and heat cycling. On a 20-year-old van, the fuse box is often the last thing owners think to replace — and the first thing that explains everything once they do. This complete OEM-spec primary fuse box assembly for the T1N Sprinter restores reliable electrical distribution across all critical systems.

What This Part Does

The primary fuse box is the main electrical distribution center for the T1N Sprinter, housing the fuses and relays that protect and control power delivery to the ignition system, lighting, fuel system, accessories, and more. Over time, the internal bus bars corrode, relay contacts oxidize, and the housing itself can crack — leading to voltage drops, intermittent faults, and system failures that are difficult to trace without replacing the assembly itself.

Common Symptoms of a Failing Fuse Box

• Repeatedly blown fuses for no apparent reason
• Intermittent electrical faults that come and go
• Multiple systems failing simultaneously
• Burnt or melted smell from the fuse box area
• Visible corrosion, discoloration, or cracking on the housing

Installation Notes

Disconnect the battery before installation. Existing serviceable fuses and relays may be transferred to the new assembly. Verify all circuits are functioning correctly after installation.
