Where is the fuse on a 2002 Lexus ES300 trunk?

The fuse panel for trunk-related circuits in a 2002 Lexus ES300 is located inside the trunk on the left side, behind a carpeted trim panel. Accessing it requires removing part of the interior trim to reach the fuse box.

This article provides a practical guide to finding and inspecting the trunk fuse box, what circuits it typically protects, and how to handle a blown fuse safely. If you don’t have the owner’s manual, the steps below will help you locate and identify the appropriate fuses and recommend when to seek professional help.

Locating the trunk fuse box

Before you work on the fuse box, it helps to know that the ES300 uses a trunk-mounted fuse panel to protect several trunk-related circuits. The box is tucked away behind the left-side trim in the cargo area, not in the engine bay.

Steps to locate the trunk fuse box:

Open the trunk and inspect the left-hand side of the cargo area where the carpeted panel is located.

Remove or peel back the trim panel to reveal the black plastic fuse box with a removable lid.

Take note of any markings on the lid or the inside of the cover that identify the fuse diagram.

Use the diagram to identify which fuse corresponds to trunk components (such as the trunk light or remote trunk release).

Once you’ve found the fuse box and the diagram, you’ll be able to inspect or replace the correct fuse as needed.

What to do if a fuse is blown

If you discover a blown fuse, replace it with a fuse of the same amperage rating shown on the diagram. Do not substitute a higher-amp fuse, as this can cause wiring damage or fire risk. If the new fuse blows again, there may be an underlying electrical fault that requires diagnostic work by a professional.

Additional notes

For precise fuse ratings and circuit mapping, consult the owner’s manual or the fuse diagram located inside the trunk fuse box cover. If you don’t have the manual, you can often find a digital copy through Lexus support resources or repair databases.

Summary

In the 2002 Lexus ES300, the trunk fuse box is typically found behind the left-side trunk trim. Access it by removing the panel, refer to the fuse diagram on the box cover to identify the trunk-related fuses, and replace any blown fuses with the same amperage. If fuses continue to blow, seek professional assistance to diagnose potential wiring faults.

What do you do when your Lexus trunk won't open?

A Lexus trunk that won't open is often caused by a faulty trunk latch actuator, a blown fuse, or a problem with the wiring. To troubleshoot, try holding the key fob button longer, locate and check for a valet switch in the glove box, and lubricate the latch mechanism. If these steps don't work, a more complex electrical or mechanical issue may require professional attention.

Quick fixes and checks

Press and hold: Hold the trunk release button on your key fob for a few seconds longer than usual, as some models require a longer press.
Valet switch: Check the glove box for a "trunk opener" button with a "cancel" or "valet" setting. If the switch is activated, it will prevent the trunk from opening. Press it to deactivate the valet mode.
Lubricate the latch: Spray a lubricant like WD-40 into the latch mechanism to free up any rust or debris. This can often fix a sticky latch.
Manual key: If your Lexus has a manual key slot, use it. If it doesn't work, the lock mechanism may be jammed. Applying graphite lubricant can sometimes help.
Jump-start the battery: If the battery is weak, the trunk release might not have enough power to function. A jump-start can provide the temporary power needed to open it.

Potential mechanical or electrical issues

Blown fuse: Locate the fuse box and check for a blown fuse related to the trunk release or central locking system.
Faulty actuator: The most common cause of a non-functioning trunk release is a faulty trunk latch actuator (the motor that opens the latch).
Wiring damage: Inspect the wiring harness that runs to the trunk for any signs of damage, fraying, or loose connections.
Valet switch recall: In the past, certain Lexus models had a recall for a faulty emergency trunk release lever. If you have a very old model, check if it's part of that campaign.

Can a fuse cause a trunk not to open?

Check fuse number 32 (red) in the fuse box for the reverse lights and trunk release circuit. A blown fuse can disable both functions. Inspect the trunk latch actuator and wiring for damage or corrosion. If the fuse is intact, test the trunk release switch and keyless remote battery.

Does the trunk have a fuse?

Yes, most cars have a fuse for the trunk's power features, but its location varies by model. It is often found in an interior fuse box, typically on the passenger side, under the dashboard, or sometimes in the trunk itself. To find it, look for a panel with a diagram on the back that identifies fuses for components like the trunk release or trunk power.

Where to find the fuse

Passenger side interior fuse box: This is the most common location for a trunk release fuse. It may be behind a panel on the side of the dashboard or under the dash.
Under the dashboard: Some cars have fuse boxes located under the dashboard, either on the driver's or passenger's side.
In the trunk: Some vehicles have a separate fuse box for trunk-related components, often located in a compartment on one side of the trunk.
Look for a diagram: The fuse box cover or the panel where it's located will usually have a diagram that shows which fuse corresponds to the trunk.

What to do if you can't find it

Check your owner's manual: The manual will have the most accurate information for your specific vehicle model.
Search online: If you can't find the fuse box, search for "[Your Car Make and Model] trunk fuse location" to see videos or forum posts from other owners.
