Used Mercedes-Benz Relay / Fuse Box (OEM 1665402450) — a genuine, used front relay and fuse box pulled from a donor vehicle. This unit also replaces 1665404902 and 1665401550. On Mercedes-Benz GL, GLE, ML, and GLS models fitted with the 3.0L V6, 4.7L V8, or 5.5L V8 gas/diesel engines, it houses relays and fuses that manage power distribution. A failing relay box can cause no-start conditions, intermittent electrical failures, or blown fuses — a direct swap restores proper circuit function.
