Resolving Power Outlet Issues on a Toyota Highlander (2020-Present)

If the power outlet in your Toyota Highlander is not working, follow this detailed guide to diagnose and fix the issue.

Step-by-Step Repair Instructions

Step 1: Check the Device

Test the Device
- Plug the device into another known working outlet.
- If the device works, the issue lies with the Highlander’s power outlet.

Step 2: Inspect the Fuse

Locate the Fuse Box
- The fuse box for the Highlander is usually located under the dashboard on the driver’s side or under the hood.
Check the Owner’s Manual
- Refer to the owner’s manual to identify the specific fuse for the power outlet (often labeled as “Power Outlet” or “Cigarette Lighter”).
Inspect the Fuse
- Use a fuse puller or tweezers to remove the fuse.
- Check the fuse for continuity using a multimeter. Set the multimeter to continuity mode, and place the probes on each end of the fuse.
- Result: If there is no continuity, replace the fuse with one of the same amperage (usually 15A).

Step 3: Verify Outlet Power

Set Up the Multimeter
- Set the multimeter to DC voltage mode.
Test the Outlet
- Insert the multimeter probes into the outlet’s terminals.
- Result: If the multimeter reads 12V, the outlet is functional. If not, further investigation is needed.

Step 4: Inspect Wiring and Connections

Access the Outlet
- Remove the panel or cover surrounding the outlet using a trim tool or screwdriver.
Inspect Connections
- Check for any loose, corroded, or damaged wires connected to the outlet.
- Ensure the wiring harness is securely connected.
Repair Wiring
- If you find damaged wires, use wire strippers to remove the damaged section and splice in a new section of wire.
- Secure connections with electrical tape or solder and heat shrink tubing.

Step 5: Reassemble and Test

Reassemble the Power Outlet
- Once repairs are made, reattach any panels or covers removed during the inspection.
Test the Outlet Again
- Plug a known working device into the outlet to verify that it now provides power.
