Use a fuse puller to remove the fuses and inspect for blown fuses.
Replace any blown fuses with new ones of the same amperage.

3. Inspect Wiring and Connections

Remove the door panel using a trim removal tool and screwdriver.
Check the wiring harness connected to the door handle mechanism for damage or disconnection.
Use a multimeter to test for continuity and proper voltage at the door handle connections.
Repair or replace any damaged wires as necessary.

4. Reset the Door Handle System

Reconnect the 12V battery.
Perform a reset of the vehicle’s systems by holding down the brake pedal and tapping the screen for a full reboot.
After rebooting, test the door handles for functionality.
