Remove the access panel if applicable to reach the lock actuator.
Disconnect the wiring harness from the lock actuator.
Test the actuator with a multimeter; if it shows no continuity, replace it.
Install the new actuator by connecting the wiring harness and securing it in place.

4. Lubricate the Latch Mechanism

Apply a silicone-based lubricant to the latch mechanism and surrounding components.
Manually operate the latch several times to ensure smooth movement.

5. Reassemble and Test

Reinstall the tailgate handle and any panels removed.
Reconnect the vehicle battery.
Test the tailgate operation using both the remote and manual release to confirm functionality.
