Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-lit area with enough space to work.
Disconnect the car's 12V battery to prevent electrical shocks or accidental deployment of the frunk latch.

2. Inspect and Access the Latch

Remove the front panel or cover that conceals the frunk latch mechanism.
- Tools Required: Socket set, trim removal tools.
- Carefully pry off any clips or screws holding the panel in place.
Once access is gained, visually inspect the latch for any visible damage or debris.

3. Test the Latch Mechanism

Manually operate the latch by pulling on the release mechanism.
If it engages, verify if it returns to its original position smoothly.
If the latch is stuck, apply a lubricant (such as WD-40) to free it up and ensure smooth operation.

4. Check Electrical Connections

Inspect the wiring and connectors leading to the frunk latch and release button for any signs of corrosion or disconnection.
Reconnect any loose wires and ensure all connectors are secure.

5. Reassemble and Test

Replace the front panel or cover, ensuring all clips and screws are securely fastened.
Reconnect the vehicle's 12V battery.
Test the frunk opening using the key fob, touchscreen, and release button to verify functionality.
