3. Inspect Trunk Latch Mechanism

Open the trunk manually.
Locate the latch mechanism; clean any debris and lubricate it with a silicone spray.
Check for any broken parts within the latch assembly and replace if necessary.

4. Check Wiring and Connectors

Remove the interior trim panel covering the trunk latch.
