Open the trunk manually if possible and locate the latch mechanism.
Visually inspect the latch for any obstruction, rust, or damage.
Check the wiring harness connected to the latch for any signs of fraying or disconnection.
Clean and lubricate the latch mechanism with a suitable lubricant (e.g., silicone spray) if necessary.

5. Check and Replace Fuse
