    The fuse panel comes with the entire cab harness. Most suffer from moisture issues from water leaks from the windshields or other cab leaks over time. Big job.....

    One of our 04 t800 last year had major corrosion issues. Picked up a good fuse box with the entire wiring harness attached from a salvage yard for $450. Took it to whiteford Kenworth body shop in south bend Indiana. They changed the box and rewired the truck. Took two days at a cost of $1500. Other shops were quoting crazy numbers but the Kenworth body shop was like no big deal. Whiteford thought it would take a day but the salvage yard cut some of the wires when they took it out of the truck so the body shop had a few wires to fix.

    I had a similar issue and all I did was replace the fuses and clean up the sockets where they plugged into the panel real good. No problems since. Might have good luck in the Garage section of the site for more information.

    Same here.
    You can remove the terminals from the fuse box by inserting a tiny precision flat blade screwdriver in the front of the fuse box to depress the locking tab of the terminal, then pull the wire (gently) out the back to clean and adjust it well. By adjust I mean get the terminal massaged so it will hold the relay blades tight.
    It was a pain, you have to be patient. The fuse box does not have much movement even with all the screws removed to get in there easily with the mass of wires coming out the back. I managed with a lot of patience and a small mechanics mirror because you can't get your head behind there to see what your doing. Totally doable though.

    Exactly. I did even less actually. I disconnected the batteries, sanded the contacts down until they were nice and shiny again then finally squeezed the contacts closer together to give a better contact for the new fuses. Of course, I don't know what the box looks like on the OP's truck but sounds like something they might want to check out.

    Another trick that can work good to clean things up........

    Put some pumice hand cleaner on the fuse or relay spades and run it in and out of the fuse/relay location that is all nastied up. The more pumice the better. The abrasives in the soap will clean the corrosion on the inside of the pin with little effort. Follow up with some electrical contact cleaner and blow dry with a blow gun or air duster. A small amount of Phillips Dielectric paste will keep the corrosion at bay. May not be a permanent fix but can definitely help get things working again.

    I have repaired some KW's with a totally melted out fuse or relay connector. They all had unused ones and I just rewired to them. Some of the Petes have room for extra circuit breakers at the bottom. Maybe just install one and wire to that if everything else looks good.

    FAQs

    Where is the interior fuse panel? ›

    Usually, you will find two fuse boxes in the car. One is located under the hood and the other is found in the dashboard or near the steering wheel.

    What fuses are in a fuse box? ›

    Your fuse box will have two sets of fuses. At the bottom will be 15-amp and 20-amp screw-in fuses with glass faces that are exposed and visible. These fuses will service branch light circuits and outlet circuits. At the top will be 30-amp or 40-amp cartridge main fuses for ovens, laundry rooms, or stoves.

    Where is the secondary fuse box? ›

    The main fuse box is typically located under the hood, while secondary fuse panels might be inside the car, often near the dashboard or steering wheel. The fuse's wire conductor breaks when the current exceeds the ampere limit, which manufacturers usually define along with different color codes on each fuse.

    Where is my fuse board? ›

    Fuse boxes are commonly found in utility rooms, porches or under-the-stairs cupboards. You may also have one in your hallway or garage. Wherever your fuse board is located, you must have easy access to it. Make sure you keep the area surrounding your fuse box clear from clutter.

    Where is my main electrical panel? ›

    If you are wondering where it is located in your house, look for the electrical service panel box in your basement or garage. Sometimes they are near your water heater or near the laundry. In apartments and some older buildings, the service panel is built into the wall.

    Where is the fuse board in my house? ›

    Fuse boxes are commonly found in utility rooms, porches or under-the-stairs cupboards. You may also have one in your hallway or garage. Wherever your fuse board is located, you must have easy access to it.

    Where is the fuse box usually in a house? ›

    Fuse boxes are typically located in your home's basement, garage, or utility room. If you have an older home, you may have a fuse box instead of a circuit breaker. Fuse boxes are not as common as they once were, but they can still be found in some homes.

    What is the interior fuse box called? ›

    A home's electrical panel is commonly referred to as a service panel or breaker panel by many electricians, but some homeowners just call it a fuse box.
