If the fuse is blown, replace it with a new fuse of the same amperage rating. Common mistakes: Using a fuse with a higher amperage rating can damage the electrical system.
3. Manually Release the Trunk
Most Subaru Outbacks have a manual trunk release located inside the cargo area. This is typically a small lever or cable that can be accessed by folding down the rear seats. Consult your owner's manual to pinpoint the exact location of this release.Activate the release and try to lift the trunk. If this works, it indicates that the problem may lie in the electronic release mechanism rather than the latch itself.
4. Check for Obstructions and Alignment
Carefully inspect the area around the trunk lid and the latch mechanism for anyobstructions, such as debris or items blocking the closure. Misalignment can also prevent the trunk from opening properly. Examine the alignment of the latch and striker plate. If they are misaligned, you may need to adjust the striker plate or the trunk hinges to ensure proper contact.
5. Investigate the Wiring and Solenoid
If the previous steps haven’t worked, the problem may be with the wiring or the solenoid responsible for releasing the trunk. This requires some basic mechanical knowledge.Disconnect the batterybefore proceeding. Inspect the wiring harness leading to the trunk lid for any signs of damage, such as cuts, frays, or corrosion. Check the solenoid's connections and ensure they are secure. You might need a multimeter to test the solenoid's functionality.
6. Reset the Power Liftgate System (If Applicable)
If your Outback has a power liftgate, try resetting the system. This can often be done bydisconnecting the car battery for about 15 minutes and then reconnecting it. This resets the car's computer and can resolve minor glitches in the power liftgate system. After reconnecting, try operating the liftgate using the key fob, the interior button, and the exterior button to see if it responds.
