Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner, and replacement fuse if needed.
Ensure the vehicle is in park and the ignition is off.

2. Inspect the Trunk Release Button

Remove the panel covering the trunk release button by unscrewing or unclipping it.
Check for any visible damage or loose wiring connections.
Clean around the button area to remove any debris.

3. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse related to the trunk release (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers. Inspect it for continuity.
If blown, replace with a fuse of the same amperage (usually 10A or 15A).
Recheck the trunk release functionality.

4. Test the Wiring

Use a multimeter to check for continuity in the wires connected to the trunk release button.
If there is no continuity, trace the wiring back to the fuse box and inspect for breaks or fraying.
Repair any damaged wiring using solder and heat shrink tubing or electrical tape.

5. Reprogram Key Fob (if necessary)

If the key fob is unresponsive, replace the battery and reprogram it according to the vehicle manual.
Test the key fob again to ensure all functions work correctly.

6. Reassemble

After repairs, reassemble all components and ensure the trunk release button is securely mounted.
Test the trunk release button and key fob functions before finalizing the assembly.
