2013 Malibu Trunk Button Not Working? Here’s the FIX!
If your 2013 Malibu’s trunk button has stopped responding, don’t panic! This is a fairly common issue, and often, the fix is simpler than you might think. This guide will walk you through troubleshooting the problem and potential solutions you can try yourself.
Understanding the Trunk Release System
Before diving into solutions, it’s helpful to understand how the trunk release system works in your 2013 Malibu. Generally, it involves:
- The Trunk Button: Located either on the key fob, dashboard, or both.
- The Body Control Module (BCM): This electronic control unit manages various vehicle functions, including the trunk release.
- Wiring and Connectors: These carry the electrical signals between the button, BCM, and trunk latch actuator.
- The Trunk Latch Actuator: This is the mechanical device that physically releases the trunk latch.
- Fuses and Relays: These protect the circuit and switch the necessary power.
When you press the trunk button, a signal is sent to the BCM, which then activates the trunk latch actuator. If any of these components fail, the trunk button will not work.
Troubleshooting Steps: Identifying the Problem
The following steps will help you narrow down the cause of your malfunctioning trunk button.
1. Check the Fuses
A blown fuse is the most common culprit.
- Location: The fuse box location varies slightly depending on your specific model, but it’s usually found inside the car (often under the dashboard or in the glove compartment) or under the hood. Consult your owner’s manual for the exact location of the fuse related to the trunk release (often labelled "TRUNK" or "REMOTE KEYLESS ENTRY").
- Inspection: Remove the fuse using a fuse puller (usually found in the fuse box) and visually inspect it. A blown fuse will have a broken filament inside.
- Replacement: Replace the blown fuse with a new fuse of the exact same amperage. Using a higher amperage fuse can damage your vehicle’s electrical system.
2. Test the Key Fob Button
If the fuse is good, check the trunk release button on your key fob.
- Battery: A weak or dead key fob battery is a common issue. Try replacing the battery with a new one.
- Functionality: If replacing the battery doesn’t help, try using your spare key fob (if available). If the spare key fob opens the trunk, the original key fob might need reprogramming or replacement.
3. Inspect the Dashboard Trunk Release Button
If your 2013 Malibu has a trunk release button on the dashboard, try using it.
- Press Firmly: Sometimes, the button might not be making proper contact. Try pressing it firmly and holding it for a few seconds.
- Listen for a Click: Listen for a faint clicking sound coming from the trunk area. This indicates that the actuator is receiving power and attempting to release the latch.
4. Check for Obstructions in the Trunk Latch
Sometimes, physical obstructions can prevent the trunk latch from releasing.
- Visual Inspection: Open the trunk (if possible – you might need to use the manual release inside the trunk) and carefully inspect the latch mechanism for any obstructions, such as loose items or debris.
- Manual Release: Refer to your owner’s manual for the location of the manual trunk release lever (usually located inside the trunk). Use this to manually open the trunk if you are unable to open it electronically.
5. Inspect the Wiring
Damage to the wiring can also cause the trunk button to malfunction.
- Visual Check: Carefully inspect the wiring harness that runs to the trunk latch area. Look for any signs of damage, such as frayed wires, corrosion, or loose connectors. Pay particular attention to areas where the wiring harness bends or is exposed to the elements.
- Connector Inspection: Disconnect the electrical connector at the trunk latch actuator. Inspect the connector pins for corrosion or damage. Clean the pins with electrical contact cleaner if necessary.
Potential Solutions
Based on the troubleshooting steps, here are some potential solutions:
- Replace a Blown Fuse: (Solution for a blown fuse). Ensure the replacement fuse has the correct amperage.
- Replace Key Fob Battery: (Solution for a weak key fob battery).
- Reprogram or Replace Key Fob: (Solution for a malfunctioning key fob). A locksmith or dealership can handle this.
- Clean or Tighten Electrical Connectors: (Solution for corroded or loose connectors). Use electrical contact cleaner.
- Replace the Trunk Latch Actuator: (Solution for a faulty actuator). This requires more technical skills.
When to Seek Professional Help:
If you’ve tried all the troubleshooting steps and the trunk button still isn’t working, it’s best to consult a qualified mechanic. They can diagnose more complex electrical issues, such as a faulty BCM or damaged wiring harness. They will also have the tools and expertise to safely repair or replace any necessary components.
Hopefully, you’ve got that 2013 malibu trunk button popping like new again! If not, don’t hesitate to check out more resources or consult a pro. Good luck!
