Common Causes
The 120V outlet in your Toyota Highlander may stop working for several simple reasons. These common causes can often be fixed without much trouble. Understanding them helps you find the problem faster and saves time.
Some issues are easy to spot. Others need a little checking under the hood or inside the cabin. Below are three main causes to check first.
Blown Fuse
A blown fuse is a common cause of power loss in the 120V outlet. Fuses protect the vehicle’s electrical system. If too much current flows, the fuse blows to prevent damage.
Check your owner’s manual to find the fuse box location. Look for a fuse labeled for the 120V outlet. If the fuse is broken or burnt, replace it with one of the same rating.
Loose Connections
Loose wiring or connectors can stop the outlet from working. Vibration and movement can cause wires to disconnect over time. This breaks the power flow to the outlet.
Inspect the outlet and wiring harness for any loose or unplugged connectors. Tighten or reconnect any loose wires carefully. A secure connection often restores power immediately.
Power Outlet Damage
Physical damage to the power outlet can cause failure. Cracks, dirt, or corrosion inside the outlet block electrical contact. This prevents devices from charging or powering up.
Look closely at the outlet for signs of wear or damage. Clean the outlet gently with a soft brush or compressed air. Replace the outlet if damage is severe or cleaning does not help.

Basic Troubleshooting
Basic troubleshooting helps find the cause of the 120V outlet problem fast. Follow these simple steps to check common issues. This saves time and avoids costly repairs.
Check The Fuse Box
Start by looking at the fuse box. The 120V outlet might have a blown fuse. Find the fuse related to the outlet in your Toyota Highlander. Replace any blown fuse with one of the same type and rating. This often fixes the issue quickly.
Inspect The Outlet
Look closely at the 120V outlet itself. Dirt, debris, or damage can stop it from working. Clean the outlet gently using a dry cloth. Make sure nothing blocks the plug connection. Check for signs of wear or damage on the outlet. Replace it if needed.
Test With Different Devices
Try plugging in various devices to the outlet. Use devices that you know work well. If none of the devices power on, the outlet might have a deeper problem. This test helps confirm if the issue is with the outlet or the device.
Resetting The Outlet
The 120V outlet in your Toyota Highlander may stop working sometimes. Resetting the outlet can often fix this issue quickly. This process is simple and requires no special tools. Follow these steps to get the power flowing again.
Locate The Reset Button
First, find the reset button near the 120V outlet. It is usually a small, recessed button. Check around the outlet or inside the nearby panel. Use a small tool or your finger to press it.
Perform A Reset
Press and hold the reset button for about 10 seconds. Release the button after holding it down. This action resets the outlet’s internal breaker. It helps clear any faults causing the power cut.
Verify Power Restoration
Plug in a device to test the outlet. Check if the device turns on or charges properly. If it works, the reset was successful. If not, repeat the reset or check the vehicle’s fuse box next.
