      Electrical issues driving you crazy in your Chevy or GMC truck? If you’ve got a 6.6L Duramax under the hood, the fuse box is often the hidden culprit. A failing panel can leave you with no-starts, flickering lights, or random accessories that quit on you mid-drive. At GoECM, we carry remanufactured Duramax fuse boxes for Silverado and Sierra models. Each one is rebuilt, tested, and programmed so it’s ready to plug in. Just match your part number, swap the unit, and your truck’s power distribution is back where it should be.

      What Is a Duramax Fuse Box?

      It’s not just a simple panel of fuses. On Duramax trucks, the fuse box—sometimes called the power distribution module—feeds critical systems like ignition, fuel, lighting, HVAC, and sensors. When it’s healthy, you don’t notice it. When it fails, you notice everything: no crank, dead lights, or accessories that seem to have a mind of their own.

      Common Duramax Fuse Box Problems

      Duramax owners have seen it all. A bad fuse box can cause:

      • Truck cranks but refuses to fire up
      • Headlights, blower motors, or wipers cutting out at random
      • Melted or overheated fuse connections (sometimes with that burnt-plastic smell)
      • Electrical accessories working one day and dead the next
      • Check engine light from sensors losing power

      If you’ve been chasing electrical gremlins across the truck, odds are the fuse box is the root of it.
