How To Turn Off Cargo Light In U Haul

Curious about how to turn off the cargo light in your U-Haul truck? It’s not surprising – cab lights are one of the most common questions our customers ask us. Cargo lights, also known as cab lights or courtesy lights, are standard features in almost every commercial vehicle produced today. These small, ambient bulbs illuminate the inside of a truck when the doors are open. They make it easier for drivers and passengers to see inside their trucks without straining their eyes during nighttime hours.

Although these lights serve a useful purpose, some people find them a bit annoying. If you’re one of those people and would rather have complete darkness inside your cab instead of illuminated illumination at night, here’s how you can turn off that particular light in your U-Haul truck.

Cargo Light Turn Off Procedure

The first step in this process is to determine the exact wiring diagram for your specific vehicle. If you don’t already know what model of truck you are driving, you can find this information by looking at the nameplate on the driver’s side of the truck.

To locate the wiring diagram for your vehicle from the nameplate, you will need to find the vehicle’s make and model, which is indicated with two letters. The first letter indicates the manufacturer, and the second letter indicates the specific model. Once you have that information, you can use it to locate the wiring diagram for your truck. The diagram is typically located on the backside of the driver”s side door frame, or in the engine compartment. The diagram is printed on a large paper poster, and will show you which wires connect to which components. You can use this diagram to help you find the wires that control the cargo light, and determine how to turn them off.

How To Turn Off The Cargo Light In U-Haul Trucks

Once you have identified the correct wires and have located the cargo light switch, you can turn off the light. The location of the switch will vary based on the model of truck you are driving.

On some trucks, the switch is located in the cab, where you can simply flip the switch to turn off the light. On other types of trucks, you may need to get out of the cab and locate the switch in the engine compartment. The engine compartment is the area of the truck where the engine is located.

Since different types of trucks have different engine compartments, it’s important you know where the cargo light switch is on your specific model of truck. To find the switch in the engine compartment, you will need to open the hood of the truck. Once the hood is open, look for the wires that control the cab light, and turn them off to turn off light.

Why You Can’t Currently Turn Off The Cargo Light In U Haul Trucks

Unfortunately, it’s not currently possible to turn off the cargo light on 2019 U-Haul trucks because the light is controlled by a sensor. In order to turn off the light, you would have to turn off the sensor as well.

A sensor is a device that monitors various aspects of a truck’s operating environment or performs a specific task. In this case, the sensor detects when the door is open and automatically turns on the cargo light.

In the past, it was possible to turn off a light controlled by a sensor by manually overriding the sensor. That meant you could physically turn off the light without closing the door. As long as you didn’t close the door, the light wouldn’t turn back on automatically. However, the light controlled by a sensor is programmed to ignore the manual override function. This means that even if you close the door, the light will remain on.

How to Install a Manual Switch to Turn Off the Cargo Light in U-Haul Trucks

If you’re tired of dealing with the cargo light every time you get in and out of your truck, you can install a manual switch to turn it off. This is a great option for anyone who drives a U-Haul truck and wants complete control over the cargo light.

The best part is that installing a manual switch is relatively straightforward, and you can do it yourself without any special tools. All you need is a pair of pliers, some electrical tape, and the correct wiring diagram so you know which wires to switch.

  • First, you need to identify the correct wires to switch. Look on the wiring diagram to find the wires that control the cargo light.
  • Once you have found the wires, you can use the pliers to cut the wires. You will need to cut two wires, and you should cut them at different points so the circuit is broken.
  • After that, you need to strip the ends of the wires and twist them together. You should use electrical tape to cover the connection to prevent any short circuits.
  • Finally, you can install the new switch and close the door. When you want to turn off the light, simply flip the switch.


Cargo lights are a standard feature in most commercial vehicles, but that doesn’t mean everyone likes them. In fact, many drivers find them to be more of a nuisance than a help, and some people would rather have total darkness inside the truck.

If you fall into that category, don’t worry! It’s simple to turn off the cargo light in U-Haul trucks. You can find the switch inside the cab, or you can install a manual switch and switch it off from the inside of the truck. Unfortunately, current U-Haul trucks don’t allow you to turn off the cargo light with the switch inside the cab. You will have to install a manual switch to turn off the light and control it manually.
