1. Trunk Lid Actuator: The trunk lid actuator is responsible for releasing the trunk latch when the key fob or interior lever is used. If the actuator is faulty or has failed, it may not be able to properly release the latch even though you hear a click. Check the actuator for any damage, corrosion, or loose connections, and replace it if necessary.
2. Trunk Latch Assembly: The trunk latch assembly is the mechanism that holds the trunk closed. If the latch is damaged, misaligned, or has worn-out components, it may not be able to release properly. Inspect the latch assembly for any damage or issues and replace it if needed.
3. Trunk Lid Release Cable: The trunk lid release cable is the physical cable that connects the interior trunk release lever to the trunk latch assembly. Over time, the cable can become stretched, frayed, or even snap, causing the release lever to become inoperative. Check the condition of the cable and replace it if it is damaged.
4. Trunk Wiring Harness: The trunk wiring harness is the bundle of wires that supplies power and control signals to the trunk lid actuator and latch assembly. Check the wiring harness for any damage or loose connections that may be causing the problem. If there is damage, you might need to replace the wiring harness.
Diagnosing the exact cause of the issue may require some troubleshooting and potentially further inspection. If you are not confident in performing these tasks, it is recommended to take your vehicle to a trusted mechanic or an authorized Infiniti service center for proper diagnosis and repair.
