Solution

1. Preparation

Gather tools and ensure the vehicle is parked safely.
Tools Required: Torx screwdriver set, multimeter, OBD-II scanner (Tesla compatible).

2. Access the Door Handle

Remove the interior door panel by unscrewing the necessary Torx screws.
Gently pry off any clips and carefully detach the panel to avoid damage to the connectors.

3. Inspect and Test the Door Handle Mechanism

Locate the door handle assembly and visually inspect it for any signs of wear or damage.
Use the multimeter to check the door handle motor's resistance; it should be within manufacturer specifications.
If the motor shows no resistance or is outside specifications, proceed to replace it.

4. Replace the Door Handle Motor (if necessary)

Disconnect the wiring harness from the door handle motor.
Remove the screws securing the motor to the assembly and replace it with a new motor.
Reconnect the wiring harness and secure the new motor with the screws.

5. Reassemble the Door Panel

Align the interior door panel back onto its mounting points and press firmly to reattach any clips.
Reinstall the Torx screws to secure the panel in place.

6. Final Testing

Reconnect the vehicle's battery (if disconnected) and test the door handles to ensure proper operation.
