Discovering the Location of the Cargo Light on a GMC Sierra

If you’re the proud owner of a GMC Sierra, then you know how convenient it can be to have a cargo light in the back of your truck. But if you’ve ever had trouble finding the switch for your cargo light, then this article is for you! We’ll show you where to locate the switch so that you can easily turn on and off your cargo light whenever needed.

The first place to check when trying to find the location of the cargo light switch on a GMC Sierra is behind the driver side kick panel. This area should have several switches that control different features within your vehicle, including an illuminated headlight symbol which indicates the location of your cargo light switch. Once located, simply flip up or down depending on whether you wish to activate or deactivate your cargo light.

Another potential spot to look for this switch is near the glove box door latch inside of your truck cab. You may need to use a flashlight or other tool in order to see it clearly, but once located again simply flip up or down depending on whether you want your lights activated or not.

Finally, one last place where some owners may find their GMC Sierra’s cargo light switch is underneath their center console armrest lid cover (if equipped). Simply lift up this cover and look around until encountering either an illuminated headlight symbol indicating its location or else a plain black toggle switch with no markings – both will work as intended when flipped up/down accordingly.

Understanding How to Turn On the Cargo Light in a GMC Sierra

If you’re a proud owner of a GMC Sierra, then you know that it can be quite the challenge to figure out how to turn on the cargo light. After all, this isn’t something that is typically included in your owner’s manual. Thankfully, we have put together this guide to help you understand how to turn on the cargo light in your GMC Sierra.

The first step is locating the switch for the cargo light. This should be located near or around the rear of your truck bed, and it will look like a small toggle switch with an illuminated symbol next to it. Once you’ve found this switch, simply flip it upwards and your cargo light should come on instantly!

Another way to turn on your GMC Sierra’s cargo light is by using your key fob remote control. Simply press and hold down the lock button for three seconds until you hear two chirps coming from inside of your vehicle. This indicates that both of its interior lights are now turned on – including the cargo light!

Exploring Common Problems When Turning On the Cargo Light in a GMC Sierra

If you own a GMC Sierra, you may have encountered issues with your cargo light not turning on. This is an issue that many GMC Sierra owners experience and can be caused by a variety of factors. In this blog post, we’ll explore some of the common problems associated with the cargo light in a GMC Sierra and how to troubleshoot them.

One possible cause of your cargo light not turning on could be due to a blown fuse. Check your owner’s manual for information about which fuse needs to be replaced for the cargo light circuit and replace it if necessary. If replacing the fuse does not solve the problem, then there may be an issue with wiring or connections related to the cargo light system itself. You should inspect all wires connected to the system and make sure they are securely attached and free from damage or corrosion.

Another potential problem when trying to turn on your cargo light is a faulty switch or relay in the system. Inspect these components for any signs of wear or damage, as well as checking for proper connection between them and their respective power sources. If any part of this electrical system appears faulty, it should be replaced immediately before attempting to use your cargo light again.

Finally, it is important to note that in some cases, there may simply be no power supplied to activate your cargo lights at all! Make sure that all fuses related to this circuit are properly installed and working correctly before proceeding further with troubleshooting steps listed above.

Investigating Solutions for Troubleshooting Issues with the Cargo Light on a GMC Sierra

If you’re having troubleshooting issues with the cargo light on your GMC Sierra, there are a few steps you can take to investigate potential solutions. First off, it’s important to determine what kind of issue is occurring with the cargo light. Is it not turning on at all? Is it flickering or dimming intermittently? Or is it staying illuminated even when the door closes? Once you’ve identified the problem, then you can begin looking for potential causes and solutions.

The most common cause for a faulty cargo light in a GMC Sierra is an electrical issue. This could be due to loose or corroded wiring connections in the fuse box or around the bulb itself. To check this, open up your vehicle’s hood and locate the fuse box. Carefully inspect all of the wires connected to it and look for any signs of corrosion or damage. If everything looks good here, then move onto inspecting each individual wire leading from the fuse box to your cargo light bulb itself – checking for any signs of fraying or breaks in insulation along its length.

In some cases, however, an electrical issue may not be present – meaning that something else must be causing your cargo light problems. One possibility is a mechanical fault such as a broken switch inside your car’s interior paneling which controls whether or not power gets sent to your lights when you open and close doors/tailgates etc.. In order to confirm if this is indeed an issue with your vehicle, try opening up both rear doors (or tailgate depending on model) while watching your lights closely – if they don’t turn on at all during this process then chances are that something has gone wrong internally within these switches themselves and will need replacing before normal operation can resume again.

Learning How to Keep Your Cargo Light Working Properly in a GMC Sierra

Keeping your cargo light working properly is essential for visibility and safety in a GMC Sierra. Fortunately, the process of ensuring that your cargo light is always functioning correctly is relatively straightforward. Here are some tips on how to keep your cargo light working properly in a GMC Sierra:

Check the Bulb

The first step in keeping your cargo light working is to check the bulb itself. If you find that it’s burned out, replace it with an identical one from an auto parts store or dealership.

Clean Connections

Make sure all connections between the bulb and wiring harness are clean and secure so they don’t corrode over time. You can use electrical contact cleaner or compressed air to remove any dirt or debris from these areas before re-connecting them securely.

Inspect Wiring Harness

Inspect the wiring harness carefully for any signs of wear or damage, as this could be causing problems with power transfer to the bulb itself. If there are any issues here, have them repaired by a professional mechanic as soon as possible so you don’t risk having further problems down the road.

Test It Out

Once everything looks good, test out your newly installed or serviced cargo light by turning it on and off several times while inspecting its performance closely each time it’s activated (i.e., does it come on immediately? Does it stay lit?). If all goes well after multiple tests then you should be good to go!


How do I know if my cargo light is working properly?

To test whether your cargo light is functioning correctly, open the trunk or tailgate of your GMC Sierra and look for a small LED bulb inside the cargo area. If it’s lit up, then your cargo light is in good working order.

Can I replace my Gmc Sierra’s cargo light myself?

Yes, you can easily replace the cargo light on your GMC Sierra yourself without requiring professional assistance. All you need to do is purchase a compatible replacement bulb from an auto parts store and follow the instructions provided by the manufacturer for installation.

Is there an easy way to access the back of my Gmc Sierra’s tailgate?

Yes, most models of GMC Sierras have a convenient access panel located in the center of their rear tailgates that allows you to get into its interior components with ease. Simply remove this panel and you should be able to gain access to any wiring or bulbs needed for replacing or repairing your vehicle’s lighting system components like its cargo lights.
